AKG Pro Audio K371BT Bluetooth Wireless Over-Ear, Closed-Back, Portable, Foldable Studio Headphones. 50mm Drivers. Astounding Frequency Response - 5 Hz to 40 kHz. Black

I was going to buy the AKG K371 but the Bluetooth was only $5 more and I can still use the wire instead. However, it makes sense that it’s only $5 more because it’s lacking common features Bluetooth headphones have such as USB-C and ANC, only having passive noise cancellation from their closed design. They do however have a built-in microphone and touch controls for play/pause and volume. AKG has an app for certain headphones, but the K371-BT is not supported. So what about the parts that are the same as the non-bt version? These headphones are extremely well-tuned, almost perfectly conforming to the Harman target. They have a removable cable that seems to be four-pin mini XLR, though the non-Bluetooth version has only three pins. They have a unique folding design that could have problems with durability. However, it lets them get much more compact. Despite the lack of extra features, the core headphones themselves earn a five-star rating because of their great sound quality and removable cable as well as the Bluetooth still being pretty useful.

When I got these, I was fine with them, I missed the bass of my previous Crushers that had fallen apart, but I also liked hearing the detail in music that was drowned out by the bass of the Crushers. I had gotten used to it, but they fell apart in less than two years. I'm not like the most gentle person with electronics, but I'm also not rough with stuff either. I use headphones daily, I take them off charge, put them on my head, do whatever, maybe take them off a few times to go outside, and at night I charge them back up. Maybe I accidentally drop them, but I don't think I've ever had any damage come from an accidental drop. The right side started falling off these headphones. Initially I repaired it with tape and stuff, and it was good enough, however after like one and a half years, these turned into headphone. The right side was gone, literally, and physically. I still have it and the broken off right side in the box somewhere, but I feel too lazy to take a picture of it. Also I do not like the weird audio port, just give me a 3.5mm. Even though I got like three cables with this, I just want my 3.5mm, everything uses it. Ever since i stopped using this, those cables have only sat and collected dust. I can't forgive this, especially for the price. I paid $134.10 in 2021, and these are still sold, with the same issue going by reviews in 2025 for $150. I upgraded to the Ankbit E600Pro for half the price in 2023, and it's better in basically every way, except there's no dedicated audio jack and it uses a USB C to 3.5mm, which I think is somehow worse. Much better bass, but not muddy or drowning other sounds out. The E600Pro like every headphones I get slowly started falling apart, but I can more easily forgive that for the price. I also repaired it with tape, JB Weld, and hot glue over the years, but it's still my main headphones, and it's still headphones, both sides are still attached and still work. There is some minor driver damage from maybe a factory defect, and I ended up getting a second E600Pro for free for that reason, but the big issue fixed itself after a while, and for general use and even music it's hard to notice unless I use ANC. I actually have another E600Pro as well. The free one I preemptively reinforced with JB Weld at break points, and the other is practically unused and I will reinforce it at some point. Just get something else. If you want a similar sound signature to the K371BT, I've heard the JBL Tune 720BT is good and much cheaper. Just get that, or anything else.

Excellent headphones while they worked, but the right channel stopped producing sound after about 13 months of light use. Contacted AKG to find out options, and it turns out that because my purchase (on Amazon) was from a third party store that was not an authorized reseller of AKG headphones, my two-year warranty is actually a no-year warranty. I can recommend these headphones as a user, but definitely ensure you get them from an authorized reseller. Saving a few bucks by not paying attention to who was selling them cost me more in the long run. Other stuff worth mentioning: - the cables are detachable (albeit with proprietary connectors) and you get several included, plus a 1/4" adapter. All good quality and sturdy. Replaceable cables are a must if you have pets who like to chew on the spicy noodles. The carry bag they come in is nice and holds everything. - The ear cups are also replaceable. I have another set of cheaper Lyx headphones that I actually preferred the sound of to these, but the ear cups start decaying after a few years and can't be replaced. Lyx could not even be bothered to answer my inquiry. - I didn't particularly care about the Bluetooth features since I was primarily using these for mixing, but it works pretty consistently and the sound quality is good. I understand AKG not wanting to cover these under warranty, but I wish there were some option other than just throwing them away. I abhor the waste. I will try to repair them, though I don't have much confidence in that. Given my mixed experience, though I liked these headphones, I am unlikely to replace them with more AKGs.

Good quality for a good price!

I’m not going to be able to add to any other review when it comes to sonic qualities, etc. I love the battery life in my K371BT. It’s solid…and the Bluetooth connection has been very stable throughout. The ONE con… is the design of the yoke. I have a wide noggin. I wear hats on the L/XL size trending more towards XL. On SnapBack hats I’m on the last two notches. The unfortunate truth about my headphone love is that I tend to go towards headphones with suspension strap systems as I find them to be more comfortable in general. That being said, I took a chance on this headphone and it’s been about two years when I the yoke cracked right about my right ear cup. The inner dimension of the headband arc makes this comfortable, however because the cups are hinged on the inside of the arc for foldability it strains the yoke down near where it connects. The plastic shielding right above the cup is completely split down the middle as the strain of the headband was just too much for the headphone after a while of trying to fine tune adjust it. It doesn’t pinch my hair thankfully as the cup has pulled that arc away from my head, but I find it to be a design flaw “for me” because the width of my head strains a good portion of headphone bands out there. So just warning. Still sounds great. Battery life is great. Yoke is crying after it cracked right above the right ear cup.

I replaced some ancient Behringer headphones with the K371-BT. I was afraid that, at my advanced age, I would notice no difference as I had always been happy with the old phones. As soon as I put them on, I was amazed at the improvement in clarity. I felt right there with the performers. I don't like the modern trend of excessive bass boost on 'phones and these deliver realistic, clearly defined bass without boost. Bass can always be added with no distortion if desired. The mid range is similarly clear and there is plenty of 'air' at the high end, or at least as high as I can hear. Voices are very present and natural, and pianos sound wonderful - the two tried and true tests of speakers or 'phones. I concur with some reviewers complaints about the Bluetooth DAC, but I would never listen to music critically via Bluetooth, it's more of a convenience feature to use with a phone or for mobile easy listening. Bluetooth is not really designed for audiophiles or pro sound engineers. I can't grade the build quality because I haven't had them long enough, but they seem sufficiently rugged. They are very comfortable in spite of being on the heavy side. External sound rejection is good, I can barely hear my cat complaining!

NOTE: I have since switched to the AKG K371 (non-BT variant) and they resolve nearly every issue I had with these. These are an interesting set of cans. I'm just going to go straight into this analysis: - These headphones have a surface material that scratches VERY easily - they have an annoying mini XLR cable gratefully detachable, but it's 4 pinned, and very obscure to replace unlike the standard 3 pin mini xlr cable with the standard non BT K371. Additionally the cable itself is legitimately *very difficult to release via the button, and i have big guitar playing hands. - The hinge system is down right ridiculously stupid. It's designed to be "portable" (but this is marketed as a professional grade studio headphone so why??), and because of that they've redesigned a way to attach the ear cups to the headband, and unfortunately it creates a bunch of issues inherent to the entire new K-line by AKG (361, 371, and both BT variants). What are those issues? 1. Well, there's a bunch of sound leak, because it applies excessive pressure on the top part of the cup and leaks on the bottom as a result. 2. The physical cups are on an adjustment bar that is very sensitive to readjustments and often doesn't ever stay in place properly. It's so stupid how bad this works because remember, theres a big sound leak issue which SUBsequently leaks all of the low frequencies. So the only solution alternatively is a pad switch, or to adjust the headphones in a way where the ear cups and headband angle can *kind* of compensate for this. BUT THAT DOESN'T WORK SO GREAT WHEN THE CUPS READJUST THEMSELVES BY BREATHING ON THEM. Let's not even get into how dysfunctional it is without this sound leak issue. Trying to reinvent the wheel in total failure. 3. The way the pressure is applied on the cup, it presses excessive force above the top of the ear, which happens to be where a small pressure point on the head is. So the result is a headphone clamp that causes mild headaches upon use. I believe as you use these, this clamp force is reduced as mentioned on headfi.org, but then I would imagine this effects the seal from the cups themselves, thus resulting in more sound leak. So these ups are just one big negative feedback. To add insult to injury, AKG designed the ear cups differently between k371 and the k371bt. The k371's are recessed differently, and as a result, the newer BT variant I'm reviewing are very, very close to the ears due to different and thinner pads. As a matter of fact, for me, with a regular shaped head and sized ears, MY EARS REST AGAINST THE DRIVER of the headphones. This is so unacceptable at this price point and for a "Professional Studio Headphone". I can't mix for more than an hour without severe ache and irritation from my ears because of this. They agitate unrelentingly, and this is the main reason I've decided to return them. The sound is okay. I myself enjoy the roundness of the low end, albeit a little bloated. The Bluetooth: -Can only connect to one device at a time. -limited Codec options make for commercial grade sound, but below average for audiophiles or "Professional Studio" use. I'm assuming this feature isn't intended for professional usecases. - The range I apparently VERY good! Which is a great surprise. There supposedly supposed to be about as good as Apple Air Pods, and better than just about every thing else tried by another user I've spoken with. - Controls are comically bad. They're touch, and I’d say anywhere between 15% and 20% of the time I can get it to work (.e. play, pause, etc). Volume control is as bad, if not worse for me. Closer to 10% of the time I'd say, without exaggeration. Finally, to touch on pad swap. I swapped to the perforated “slanted” pad made by BRAINWAVZ and while I didn’t mind the original sound signature in it’s lows, this pad swap has created a much more balanced sound in the lows, while also making the signature much more interesting in the upper mids and treble. They add a little bit of pleasing air, scoop out some of the excessive fattiness in the sup bass, making it more shapely overall, while also, and to my great appreciation, reduce some of the abrasive mids that can come off “shouty” in the original pad response. Finally, something that is definitely worth noting and praising that you did not mention, is that the perforated pads create a SIGNIFICANT breathe-ability in the ear cup with the cans on which is not only adding to the “airiness” on top, in the treble register, but also helping tremendously with long recording sessions. Before, the stock pads would not only kill the ears with achiness and irritability, they would get VERY sweaty and hot in reasonable 1.5+ hour recording sessions. These new BRAINWAVZ perforated pads for the ATX line are substantially more breathable, which would seem obvious, but I didn’t expect it to be this much better. Humidity never really exceeds 60% of what the original pads did after an hour and a half. And that is a huge difference. Also, on the subject of these pads and the “on-ear” fit. They do fit kinda half on ear half off, because there is an inward slant that goes towards the inside of the cup. Now, I myself am sensitive to this idea, but for some reason it doesn’t feel noticeable uncomfortable or agitating. I don’t really know why that is but I’m very grateful. Conclusion: I like the sound, the fact that the cable is detachable, and the Bluetooth sound is actually pretty darn good compared to others. But, too many other issues. Sure, with the extra pads, 3, or even 3.5 would be reasonable IMHO. But with the number of fundamental issues like the stupid hinge design (Why are they adding “portability” design to a studio headphone FFS?), and thus, awful sound leak, as well as very poor Bluetooth controls, the strange clamp force headache, and very poor ear cup design... These design flaws are so fundamental, that they’re inexcusable to me as a consumer And bear in mind my body dimensions are very average. Perhaps on the slimmer athletic side with normal head size and ear size. Not to sound harsh, but the issues are so basic that they deserve to be highly criticized IMO. My final score would be 2-2.5 stars.

The good: The sound quality is decent, but I'm not really an audiophile so this is purely subjective. I liked the balance of the sound and it wasn't too bassy like others I've used. The overall fit was comfortable and fit nicely over my ears. They do get a little warm after extended use but thats to be expected with closed back headphones. The acceptable: The cups were not that deeps so you can definitely feel the driver against your ear pushing a little bit. The headphones don't have a vicelike grip but you definitely feel some clamping pressure which can get a little painful after a while. The bluetooth connectivity was good but would randomly disconnect even when there was sufficient battery life left, it was a bit annoying but turning it off and back on seemed to restore it so I could live with it. The bad: Firstly, the build quality isn't great, it feels a bit cheap compared to other AKG models. This was very very evident after the headband snapped above the right earcup. I've had these for just under 2 months, only used them at my pc, never outside and no physical activity. They have absolutely no reason to snap so quickly or easily. To make matters worse, it is no longer eligible for an Amazon return. I've contacted AKG/Harman for a warranty claim and will edit this review based on their response. Secondly, the touch controls for the pause/play and volume controls are absolutely useless. They do not respond correctly no matter how much I try it. I wish they just used a few simple buttons instead of the touch controls. I've had cheap headphones that have lasted much longer than these supposed mid-tier headphones, extremely disappointing and I assume not representative of their brand but they definitely don't leave a good impression. Overall: Decent headphones if they don't break on you. Spend a bit more and get a pair of Sony's or Bose headphones.
