JBL Tune 670NC Review: 70 Hour Battery & Adaptive ANC

Cheap headphones used to mean bad headphones. That rule does not hold anymore. The JBL Tune 670NC sits in the budget aisle, yet it carries adaptive noise cancelling, Bluetooth 5.3, multi point pairing, and a battery that runs for days.

I spent weeks with this pair on trains, in cafes, at a desk, and on a treadmill. Some parts impressed me. Some parts reminded me exactly how much I paid. This review covers all of it in plain language, so you can decide fast.

You will learn how the JBL Tune 670NC sounds, how well the ANC blocks noise, how comfortable it feels after three hours, and where it loses to slightly pricier rivals. You will also see three strong alternatives, a full pros and cons list, and answers to the questions buyers ask most.

Keep reading. By the end you will know if this is your next daily driver or a pass.

In a Nutshell

Here is the short version for readers who want the verdict now.

• Battery life is the headline feature. JBL rates the Tune 670NC at 70 hours with ANC off and 44 hours with ANC on. A five minute charge adds three hours of playback. A full charge takes about two hours over USB C.
• Sound leans warm and bass forward. JBL Pure Bass tuning pushes low frequencies hard. Hip hop, pop, and electronic tracks hit with energy. Acoustic and vocal jazz sound a little thick until you fix the EQ in the app.
• Adaptive noise cancelling works, within limits. Two microphones cut steady low rumble like bus engines, air conditioning, and plane cabin drone. Sharp sounds such as voices and keyboard clicks still get through.
• Comfort is excellent for an on ear pair. At 174 grams, it barely presses on your head. Sessions under two hours feel fine. Longer sessions create mild ear pressure because the pads sit on your ears, not around them.
• The feature list punches above the price. You get Bluetooth 5.3, multi point connection, Ambient Aware, TalkThru, VoiceAware, a detachable audio cable, flat folding hinges, and full EQ control in the JBL Headphones app.
• Compromises are real but fair. There is no carrying case, no wear detection, and no aptX or LDAC support. Plastic dominates the build. None of that surprises anyone at this price.

Bottom line: the JBL Tune 670NC is a smart buy for students, commuters, and anyone who wants long battery life and decent ANC without spending big money.

JBL Tune 670NC Overview

Last update on 2026-09-04 / Affiliate links / Images from Amazon Product Advertising API

The JBL Tune 670NC is a wireless on ear headphone with adaptive noise cancelling. JBL placed it in the Tune line, which is the brand’s value tier. It sits above the Tune 520BT and below the over ear Tune 770NC.

The specs read well. Inside each cup sits a 32 mm dynamic driver. Frequency response covers 20 Hz to 20 kHz. Impedance measures 32 ohms and sensitivity hits 98 dB at 1 kHz.

Weight lands at 174 grams, or 6.1 ounces. That number matters more than most people expect. Light headphones stay comfortable longer, and this pair feels almost weightless on your head.

Connectivity uses Bluetooth 5.3 with LE Audio support delivered through a firmware update. Two microphones handle both calls and noise sensing. Multi point pairing lets you hold two devices at once.

In the box you get the headphones, a USB C charging cable, a detachable 1.2 metre audio cable, a warranty card, and a quick start guide. No case. You fold the cups flat and drop them in your bag.

JBL lists this model near eighty dollars, though street prices often fall well below sixty during sales. Always check the live price before you buy, because this model discounts often.

Colors include black, white, blue, and purple. The purple version has become surprisingly popular with students.

Design and Build Quality

Plastic covers almost every surface. That sounds like a complaint, and partly it is, but the plastic feels dense rather than hollow. Nothing creaks when you twist the frame.

The headband uses a matte finish with light padding along the underside. Sliders move with firm clicks and hold their position well. I never had the fit drift mid session.

Ear cups measure 7.3 cm across and 3.7 cm deep. They rotate flat, which makes the pair easy to slide into a laptop sleeve or backpack pocket. The hinges also fold inward for a smaller footprint.

Buttons handle every control here, and I count that as a win. You get volume up, volume down, a multifunction centre button, an ANC and ambient button, and a power switch. Physical buttons never misread a sweaty finger the way touch panels do.

The USB C port and the 3.5 mm jack both sit on the left cup. The detachable cable means you can listen with a dead battery, which many cheap ANC models refuse to do.

Fingerprints show up on the glossy inner ring around each cup. A quick wipe fixes that. The pads use protein leather that looks clean after months of use, though it will eventually flake like all pads in this class.

Nothing here feels premium, yet nothing feels fragile either. For a pair you toss in a bag daily, that balance is the right one.

Comfort and Fit for Long Sessions

Comfort comes down to two things on this pair: low weight and light clamp. JBL got both right.

The 174 gram frame sits so lightly that I forgot I was wearing it during work calls. Compare that to many over ear ANC models that weigh 250 grams or more.

Clamping force feels gentle. Your ears do not get squeezed, and the headband spreads pressure across a wide area instead of a single hot spot.

There is a catch, and it is the on ear format itself. The pads rest on your ears rather than around them. After roughly two hours, most people feel warmth and mild soreness on the outer ear cartilage.

I found the sweet spot at ninety minutes per session. A short break resets everything. If you plan eight hour listening marathons, an over ear model like the Tune 770NC suits you better.

Glasses wearers get good news. The soft pads seal around temple arms without pinching, and audio quality barely changes.

Heat buildup stays moderate. On ear designs breathe better than over ear cups, so summer use feels less sticky than you might fear.

For workouts, the fit holds during walking, cycling, and light gym work. Running shakes them loose eventually because there is no sport specific grip. Treat this as a commute and study headphone rather than a running headphone.

Top 3 Alternative for JBL Tune 670NC

If the Tune 670NC almost fits your needs but misses on one point, these three options cover the gaps. Each one solves a different problem.

Sony WH CH720N gives you an over ear fit with better ANC processing. Sony uses a dedicated V1 chip, and it shows in how much low frequency noise disappears. Battery runs about 35 hours with ANC on, which is less than JBL offers, but the sound signature is more balanced out of the box. Pick this if all day comfort and cleaner mids matter more than raw endurance.

Soundcore by Anker Q30 remains the value ANC champion. It packs 40 mm drivers, hybrid active noise cancelling with multiple modes, and up to 40 hours with ANC on. It also ships with a hard carrying case, something JBL skips. Pick this if you want the strongest noise blocking for the lowest price.

JBL Tune 770NC is the direct upgrade inside the same family. You keep the JBL app, the same button layout, and the same 70 hour rating, but you move to an over ear design with larger 40 mm drivers. Comfort improves a lot on long flights. Pick this if you liked everything about the 670NC except the on ear pads.

Sound Quality and JBL Pure Bass

JBL tunes these for fun, not for accuracy. Bass arrives first, loud and confident, and it stays in charge unless you change the EQ.

Sub bass has real weight for a 32 mm driver. Kick drums thump and bass lines rumble in a way that makes playlists feel alive. Hip hop, EDM, pop, and modern rock all benefit from this tuning.

Mids sit slightly behind the bass. Male vocals sometimes sound thicker than they should, and rhythm guitars lose a little bite. Female vocals fare better and stay clear.

Treble stays polite. JBL smoothed the upper range so cymbals never turn harsh, which helps during long listening. The trade off is reduced detail and a smaller sense of air around instruments.

Soundstage feels narrow, as expected from a closed on ear design. Instruments feel close to your head rather than spread out in front of you.

Here is the fix that changed my opinion. Open the JBL Headphones app, drop the bass slider by two or three notches, and lift the 2 kHz to 4 kHz region slightly. Vocals snap into focus and the whole presentation cleans up.

Wired listening through the detachable cable sounds a touch tighter than Bluetooth. Codec support covers SBC and AAC, so Android users on aptX or LDAC gear will notice the missing high resolution option.

Volume goes plenty loud. At sixty percent on a phone, most tracks already feel full.

Adaptive Noise Cancelling Performance

Adaptive ANC on the Tune 670NC uses two microphones to measure outside noise and adjust cancellation in real time. It does not require manual level tuning, which keeps things simple.

Low frequency noise takes the biggest hit. Bus engines, subway rumble, plane cabin drone, refrigerator hum, and air conditioning all drop noticeably. On a metro ride, engine noise fell to a soft background wash.

Mid frequency noise gets partial treatment. Office chatter becomes quieter and less distracting, but words remain audible if someone speaks near you.

High frequency noise mostly survives. Keyboard clicks, cutlery, and sharp voices still cut through. This is normal for ANC at this price, and pricier models handle it only somewhat better.

The on ear design limits the ceiling here. Over ear cups create a physical seal that blocks noise before the electronics even start working. On ear pads cannot match that passive isolation.

I noticed almost no hiss when ANC engages with no music playing. That matters, because cheap ANC often adds a background whoosh that annoys quiet listeners.

There is also no ear pressure sensation, the odd suction feeling that stronger ANC systems create. Sensitive listeners will appreciate that.

My honest take: this ANC turns a noisy commute into a manageable one, but it will not create silence. Add music at moderate volume and outside noise practically vanishes.

Ambient Aware and TalkThru Modes

JBL includes two ways to hear the outside world without pulling the headphones off. They serve different purposes, and the difference is worth knowing.

Ambient Aware feeds outside sound into the cups while your music keeps playing at normal volume. Use it while crossing a street or walking through a busy station. You stay aware of traffic and announcements.

TalkThru drops your music volume sharply and boosts voice frequencies. Use it for a quick chat with a barista or a colleague. Conversation feels natural and you never touch your phone.

Switching happens with the dedicated button on the cup. You can also assign modes inside the JBL Headphones app if the default cycle annoys you.

Sound quality in these modes is functional rather than natural. Voices come through clearly, but there is a slight processed edge and a mild amplification of wind noise outdoors.

Compare that to premium transparency modes on flagship headphones, which sound almost like wearing nothing. This is a step below, though it still does the job.

Latency in ambient mode is low enough that your own voice does not sound delayed. That prevents the strange echo effect that ruins cheaper implementations.

I used TalkThru far more than I expected. Grabbing coffee without removing headphones turns into a small daily convenience that adds up.

Battery Life and Speed Charge

Battery performance is where the Tune 670NC embarrasses far more expensive headphones. JBL claims 70 hours with ANC off and 44 hours with ANC on.

Real world use matched those figures closely. With ANC on at about sixty percent volume, I averaged roughly 42 hours per charge, which lined up with the rating.

Think about what that means. A one hour commute each way, five days a week, uses ten hours. You charge this pair roughly once a month under that pattern.

Speed charging covers emergencies. Five minutes on a USB C cable adds three hours of playback. That is enough for a flight or a long study block.

A full charge from empty takes about two hours. Any standard phone charger handles it, and the port sits on the left cup for easy access.

Battery reporting works through the JBL app and through your phone’s Bluetooth menu. Voice prompts also announce charge status when you power on.

If the battery dies completely, the detachable 3.5 mm cable saves you. Wired mode works with zero charge, though ANC and app features switch off.

One small note. Standby drain is low but not zero, so a pair left unused for two months will lose some charge. Power it off with the switch instead of leaving it idle.

Bluetooth 5.3, LE Audio, and Multi Point Connection

Wireless performance impressed me more than the spec sheet suggested. Bluetooth 5.3 keeps the connection stable in crowded places where cheaper headphones stutter.

I walked through a busy shopping centre and a train platform with no dropouts. Range held past ten metres indoors with a wall in between.

Multi point connection is the standout convenience feature. Pair your laptop and your phone at the same time. Watch a video on the laptop, then answer a phone call, and audio switches over automatically.

Switching takes a second or two and works reliably. Anyone who juggles work calls and personal devices will use this daily.

LE Audio arrives through a firmware update rather than out of the box. It brings the LC3 codec, which improves efficiency and can reduce latency. Check for updates in the JBL app after unboxing.

The app also includes a Smart Audio and Video toggle. Audio mode prioritises sound quality. Video mode cuts latency so lip sync stays tight during movies and casual games.

I tested video mode on YouTube and mobile games. Lag dropped to a level I stopped noticing, though competitive gamers still need a wired connection.

Pairing itself is painless. Hold the power switch, look for the pair in your device list, and listen for the voice prompt. Voice prompts come in multiple languages and you can change them in the app.

Call Quality and VoiceAware

Two microphones handle voice pickup. They are not beamforming mics, so expectations should stay realistic.

In quiet rooms, callers reported clear and natural sounding audio. My voice came through with decent body and no robotic artifacts.

Outdoors, results dropped. Wind and traffic bleed into the pickup, and callers described my voice as thinner with background noise present. It stayed understandable, just not clean.

VoiceAware is the feature worth highlighting. It feeds a portion of your own voice back into the cups while you speak. You stop shouting and your calls sound more relaxed.

The app lets you adjust how much of your voice returns. I set mine near the middle, which felt natural without being distracting.

Call controls sit on the multifunction button. One press answers or ends. A long press rejects. Volume buttons work during calls too.

For video meetings on a laptop, this pair performs well enough for daily standups and lectures. For client presentations from a noisy cafe, a dedicated headset does better.

Voice assistant access works through the same button, connecting you to Google Assistant or Siri depending on your phone.

Summary on calls: good indoors, acceptable outdoors, and much better than the old Tune models thanks to VoiceAware.

JBL Headphones App and Customisation

The JBL Headphones app turns this pair from decent into genuinely flexible. Downloading it is not optional in my view.

The EQ section offers preset curves plus a fully manual graphic equaliser. You can save custom profiles and switch between them for music, podcasts, and movies.

Ambient sound control lives here too. You choose between ANC, Ambient Aware, and TalkThru, and you set which modes the physical button cycles through.

Firmware updates come through the app, and this is how LE Audio support arrives. Updates take a few minutes and the app walks you through each step.

Other useful toggles include VoiceAware level, voice prompt language, auto power off timing, and the Smart Audio and Video mode switch.

The interface is clean and quick. Connection to the headphones happens automatically when you open the app, with no login required for basic features.

A few things are missing. There is no wear detection, so no auto pause when you remove the headphones. There is also no find my headphones feature and no spatial audio processing, which the pricier Tune 780NC offers.

The app is stable, which matters. Some budget brands ship buggy companion apps that crash or lose settings. I had no such problems here across weeks of use.

JBL Tune 670NC vs Tune 770NC vs Live 670NC

Buyers get confused by JBL naming, so let me clear it up quickly.

The Tune 670NC is the on ear model in this review. It uses 32 mm drivers, weighs 174 grams, and rates 70 hours with ANC off.

The Tune 770NC is the over ear version at the same tier. It moves to 40 mm drivers and full ear enclosure, which improves passive isolation and long session comfort. Battery rating stays at 70 hours. It costs a little more and it is the pair I recommend for flights.

The Live 670NC sits in the higher Live line. It is also on ear, but it adds a more refined tuning, better microphones, and JBL’s True Adaptive ANC with real time calibration. Battery drops slightly to around 65 hours. Price roughly doubles.

There is also the Tune 680NC and Tune 780NC, which add spatial sound and higher resolution tuning.

So which one? If you want the lowest price with real ANC and huge battery life, the Tune 670NC wins. If you want comfort for long haul travel, spend a bit more on the 770NC. If sound quality is your priority and budget allows, the Live series delivers a clear step up.

Skip the Live 670NC if the extra spend hurts. The gap in real world enjoyment is smaller than the price gap suggests.

Who Should Buy the JBL Tune 670NC

No products found.

This pair fits some people perfectly and disappoints others. Here is how to tell which group you are in.

Buy it if you commute daily. Light weight, flat folding hinges, and ANC that kills engine rumble make bus and train rides much quieter.

Buy it if you are a student. The price fits a tight budget, the battery survives a full week of classes, and the app EQ adapts to lectures or music.

Buy it if you hate charging things. Forty plus hours with ANC on means you charge monthly rather than nightly.

Buy it if you work hybrid. Multi point pairing plus VoiceAware handles laptop meetings and phone calls without fuss.

Skip it if you need studio accuracy. The bass forward tuning serves fun listening, not critical mixing work.

Skip it if you wear headphones for six hours straight. On ear pads will start to hurt long before that. Choose an over ear model instead.

Skip it if you fly often on long routes. Stronger ANC and full ear cups matter on a ten hour flight.

Skip it if you chase high resolution codecs. SBC and AAC only means Android audiophiles will feel limited.

Match the headphone to your routine, and the Tune 670NC becomes an easy recommendation.

Final Verdict

The JBL Tune 670NC delivers more than its price tag suggests. Battery life is outstanding, features are generous, and the sound is enjoyable once you touch the EQ.

Noise cancelling handles the noise most people actually face, which is engine drone and background hum. It will not silence a chatty office, and it does not pretend to.

Comfort is genuinely good for short and medium sessions thanks to that 174 gram frame. The on ear format is the main limitation, and it is a fair trade at this cost.

My rating sits at 4.2 out of 5 for value at this price. Nothing here feels cheap in operation, and the app support adds real long term flexibility.

Would I recommend it? Yes, for students, commuters, and casual listeners who want solid ANC without spending premium money.

Would I recommend it to an audiophile? No. Look at the Live line or step up to over ear competition.

The JBL Tune 670NC is a sensible, likeable, low cost headphone that does the basics very well. That is exactly what most buyers need.
