The Audio-Technica M50xBT are a good sounding wireless pair of headphones for critical listening. They are the wireless variant of the very popular wired ATH-M50x and perform quite similarly. They have a good audio reproduction, which isn’t as great as the wired equivalent, but their build is practically the same, making the M50xBT quite comfortable and durable headphones. They have an excellent battery life, but their compatible app doesn’t offer much, which is disappointing. They also have too much latency to watch video content, but on the upside, they can also be used passively with the included audio cable and get rid of the latency issues, even if the battery is dead.
The Audio-Technica ATH-M50xBT are practically identical to the regular wired ATH-M50x when it comes to design, other than the fact they can be used wirelessly. They have the same studio-like look and the same dense plastic build quality that feels solid and well-made. The padding isn’t much different and is still fairly comfortable. The cups are larger to fit most ears, and the headphones don’t apply too much pressure on the head. On the wireless variant, you now get a nice and easy to use control scheme on the ear cups. You can also use the headphones wired with the provided 1/8” TRRS cable, even if the battery is dead.
The Audio-Technica ATH-M50xBT isn’t very different from their wired equivalent ATH-M50x. They have the same bland studio look with an all-black design that some may like. They also still have silver accents on the ear cups around the company logo, and overall, they look good, but won’t stand out. Unfortunately, they do not come in any color variant to fit your preferred style like the wired ATH-M50x.
The Audio-Technica ATH-M50xBT are built very similarly to the regular wired M50x and are as comfortable. They are larger than the ATH-M40x, which makes them a bit more comfortable and suitable for larger ears, but are on the shallow side. The headphones are fairly lightweight and don’t apply too much pressure on the head and don’t feel too tight. The padding on the ear cups is comfortable but might feel bit stiff right out of the box.
Unlike the M50x, the Bluetooth variant has controls on the ear cups for on the fly functionalities. You get a volume control, play/call management button and you can also access your device voice assistant like Siri or Google Assistant with a long touch over the logo on the left ear cup. However, it is finicky and doesn’t seem to work consistently. Also, there’s no button to go into pairing mode. The headphones will automatically connect to the last known device, and if you want to connect to another device, you’ll have to disconnect manually on the first device, and then the headphones will search for available devices. There is no way to disconnect Bluetooth directly on the headphones, and this might be a deal breaker for some if you have multiple devices. The control scheme is fairly easy to use, and the provided feedback from the physical buttons is good. You also get audio feedback for track skipping, min/max volume and also play/pause music.
Like most over-ears, the ATH-M50xBT trap heat under the ear cups. These headphones are not designed to be sports headphones, and you should expect more sweat if you’re using them during your workouts. This shouldn’t be too much of a problem for casual listening, but breaks are recommended to let the ears cool off.
The Audio-Technica M50xBT aren’t very portable over-ear headphones, but they do fold into a more compact format and can be easily stored in a bag. They also have swiveling cups to lay flat, which makes them more comfortable to wear around your neck when not using them. They also come with a soft pouch to protect them during traveling.
The ATH-M50xBT are practically the normal M50x, but without a cable. They are made of dense plastic that gives them a durable and well-built feel. The headband is also reinforced with a metal frame and doesn’t feel flimsy. Like most of the Audio-Technica lineup, the joints seem to be the weak spots of the headphones and could be the first thing susceptible of breaking.
The Audio-Technica ATH-M50xBT headphones were not designed for sports and aren’t stable on the head. During sports and high-intensity activities, they will slip off your ears. This shouldn’t be a problem for casual listening, and since they have a wireless design, you don’t have to worry about a cable getting stuck on something and snagging the headphones off your head.
The Audio-Technica ATH-M50xBT come with a USB to micro USB charging cable and also a 1/8” TRRS cable for when you want to use the headphones wired, even if the battery is dead. This cable has an in-line remote and microphone. They also don't have a twist-and-lock mechanism like the wired M50x, so you can use them with any 1/8" TRS/TRRS cable.
The Audio-Technica M50xBT is a good sounding pair of closed-back over-ear headphones. They have a deep and punchy bass, a good and well-balanced mid-range and a great treble. This makes them suitable for a variety of music genres, especially bass-heavy ones. However, the bass is a bit overemphasized and might sound boomy, the mid-range is recessed, meaning vocals and leads will sound a bit thin, while the treble is rather uneven, and some S and T sounds are going to lack detail while some sound a bit sharp. Their bass delivery can also be inconsistent, especially for people wearing glasses that can break the air-tight seal around your ears.
The bass response is great. LFE (low-frequency extension) is at 10Hz, which is excellent. Also, the whole bass response is well-balanced and even but slightly overemphasized by about 2.5dB. This gives these headphones a bit of extra thump and rumble which some may like, especially fans of bass-heavy genres. However, they tend to sound a bit boomy due to the high-bass overemphasis.
The mid-range performance is good. The overall response is fairly flat, but with an audible dip in the low-mid and mid-mid ranges. This will make vocals and lead instruments sound thin and pushed to the back of the mix.
The treble performance is very good. The response is rather uneven, but well-balanced across the whole range. However, the dip around 6KHz will make vocals, leads, and cymbals lack a bit of detail and brightness. On the other hand, the peak at 10KHz could make the S and Ts sound a bit sharp on already bright tracks.
The frequency response consistency is average. In the bass range, the biggest deviation measured was 10dB at 20Hz, which was measured on the human subject wearing glasses. In higher frequencies, they seem to vary by less than 5dB, below 10KHz, between re-seats, which is good. When comparing these results to the wired ATH-M50x, consider that our human test subject with glasses wasn’t present during the frequency response consistency testing on the wired variant, and we expect both models to perform similarly.
The Audio-Technica M50xBT have good imaging. Their weighted group delay is 0.36, which is very good. The graph also shows that the group delay is almost entirely below the audibility threshold. This ensures a tight bass and a transparent treble reproduction. Additionally, the L/R drivers of our test unit were well-matched in amplitude, frequency, and phase response, which is important for the accurate placement and localization of objects (voices, instruments, video games effects) in the stereo image.
The soundstage of the wireless M50xBT is sub-par. The PRTF graph shows decent accuracy and a good amount of pinna activation. However, there is not a notch present around 10KHz, meaning that the soundstage will be perceived to be located inside the listener’s head instead of in-front.
The harmonic distortion performance is decent. The overall amount of harmonic distortion produced is not too high, especially in the mid-range. Also, there is not a big rise in THD under heavier loads, especially in the bass range, which is good. However, the peak around 6KHz could make the treble of these headphones harsh and impure.
The Audio-Technica ATH-M50xBT have sub-par noise isolation performance. They only block ambient noise passively since they do not have an active noise canceling (ANC) feature. This also means that they won’t block lower frequencies like plane and bus engines and won’t be a great choice for commuting. You can mask more background noise by raising your listening volume but be careful as they do tend to leak a bit and might be disturbing for people surrounding you.
The isolation performance is sub-par. These headphones don't have active noise cancelation and do not provide any isolation in the bass range. This means they will let in all the rumbling of engines. In the mid-range, important for blocking out speech, they isolate by about 9dB, which is average. In the treble range, occupied by sharp sounds like S and Ts, they achieved 30dB of isolation, which is good.
The leakage performance is average. The significant portion of their leakage is spread across the mid and treble ranges, between 400Hz and 6KHz, which is broad. However, the overall level of the leakage is not very loud. With the music at 100dB SPL, the leakage averages at 43dB SPL and peaks at around 54dB SPL at 1 foot away, which is about the noise floor of most offices.
The Audio-Technica ATH-M50xBT have an average microphone. In quiet environments, speech recorded or transmitted with this mic will sound relatively thin, noticeably muffled, and lacking in detail. The microphone is also prone to lower frequency artifacts and pops. In noisy situations, it will struggle to separate speech from ambient noise, even in moderately loud environments such as a busy street.
The recording quality of the integrated microphone is above-average. The bump around 50-100hz indicates this mic might be prone to lower frequency noise and pops. The HFE (high-frequency extension) of 3.5KHz means that speech will be noticeably muffled and lacking detail. However, the limited high-frequency extension is a limitation of the Bluetooth protocol and is a problem with all Bluetooth microphones.
The integrated mic is mediocre at noise-handling. In our SpNR test, the ATH-M50xBT achieved a speech-to-noise ratio of 11.5dB, indicating they are best suited for quiet environments and will struggle to separate speech from ambient noise in moderate and loud situations.
The Audio-Technica M50xBT have great battery life but come with a lackluster app that doesn’t really give you any options to enhance your listening experience. Their 38-hour battery life will be more than enough to last you a few days, but their long charge time might be too much for some, especially since they do not have any quick charge feature. The app doesn’t offer an EQ or presets to customize the sound to your liking, which is disappointing. On the upside, they can be used passively, even if the battery is dead, and can be used while charging.
The battery life of the ATH-M50xBT is excellent with about 38 hours of continuous playback. They should easily last you a few days even if you are an avid listener. However, they take about 5 hours to charge fully, which is above-average and might be too long for some. They also don’t have any power saving features to extend battery life. On the upside, you can still use them with the Bluetooth connection while they are charging with the USB cable. Even if the battery dies, you can also use the included 1/8” TRRS audio cable to use the headphones passively.
The companion app for the Audio-Technica M50xBT is lackluster. The app lets you know the last known location of the headphones, the battery life and the option to choose the codec connection. You do not get any customization options to enhance your listening experience, which is disappointing. Also, we had trouble with the Android version of the app, which would take several seconds, even minutes, to connect. It kept searching for a device and restarting the app seemed to solve the issue sometimes.
The Audio-Technica M50xBT are Bluetooth headphones that can also be used wired with the included 1/8” TRRS audio cable. They support Bluetooth 5.0, so you might experience better range and connection reliability than what we measured. Also, they have excellent wireless range, but unfortunately, they don’t support NFC and can’t connect to 2 devices simultaneously. Latency is also high, but this is common with Bluetooth headphones, and you can use the headphones wired to get rid of latency issues.
The Audio-Technica ATH-M50xBT headphones support Bluetooth version 5.0, so you could get better results in wireless range than what we measured on our test bench which currently only supports Bluetooth 4.2. Unfortunately, they do not support NFC and can’t connect to multiple devices simultaneously. Also, there’s no button to go into pairing mode. The headphones will automatically connect to the last known device, and if you want to connect to another device, you’ll have to disconnect manually on the first device, and then the headphones will search for available devices. There is no way to disconnect Bluetooth directly on the headphones, and this might be a deal breaker for some if you have multiple devices.
You can use the provided 1/8” TRRS cable to use the ATH-M50xBT passively, which will also get rid of latency issues. You can also use the headphones wired when the battery is dead which is very convenient. The in-line remote works with consoles and PC and the headphones have audio and microphone support.
The Audio-Technica ATH-M50xBT do not have a base/dock. If you want a versatile headset with a base that you can also use wired, check out the SteelSeries Arctis 7.
The Audio-Technica ATH-M50xBT have excellent wireless range, especially when obstructed. We measured one of the longest distances we’ve had so far when the source was obstructed, which means you should be able to leave your desk or your phone at one place and move around with the headphones without hearing audio cuts. They also have a great line of sight range with 174 feet. You shouldn’t have any issues, especially if you keep your audio source on you during workouts.
Like most Bluetooth headphones, the ATH-M50xBT have too much latency to be suitable for watching video content and gaming. However, they do support the aptX codec, but the latency issues will still be noticeable. You can use the headphones passively with the 1/8” TRRS cable to get rid of these problems.
The Audio-Technica M50xBT are good wireless headphones for critical listening. They have a good and well-balanced audio reproduction, suitable for a wide variety of music genres. They are the wireless equivalent of the very popular wired ATH-M50x, and their good build quality is practically the same. They also have wide and well-padded ear cups that should fit most ears. They have controls on the ear cup and can also be used wired with the included audio cable, even if the battery is dead. See our recommendations for the best wireless headphones, the best studio headphones and the best headphones under $200.
Both headphones have a similar design and performance, but the Audio-Technica ATH-M50xBT are better mixed-usage headphones than the regular wired Audio-Technica ATH-M50x which are better for studio use. The M50xBT are wireless, which makes them more convenient to use, and they have a decent control scheme on the ear cups, while the wired model doesn’t have any. On the other hand, the regular M50x have a more balanced audio reproduction, and you don’t have to worry about latency issues or battery life, but the 38 hours of playback time you get with the M50xBT is excellent.
The Sennheiser HD 4.50 are better headphones than the Audio-Technica ATH-M50xBT. They have a decent noise cancelling feature that the M50xBT lack. Also, even if their treble range is slightly recessed, they are compatible with a great app that lets you EQ the sound signature to your liking and can connect to 2 devices simultaneously, which is convenient. However, the ATH-M50xBT have almost twice the battery life, a better microphone for calls, better wireless range, and are slightly more comfortable. They do take a lot more time to charge overall.
The Sony WH-CH700N are slightly better headphones than the Audio-Technica ATH-M50xBT. They are compatible with the Sony Headphones Connect app which allows lots of sound customization options, while the Audio-Technica app lacks features. Also, they are noise cancelling headphones, but this feature doesn’t actually seem to perform well. The Sonys are also very sensitive to glasses. On the other hand, the Audio-Technicas are better-built headphones and have better wireless range thanks to the Bluetooth 5.0 support.
The Bose SoundLink Around-Ear II are better headphones than the Audio-Technica ATH-M50xBT. They are one of the most comfortable headphones we’ve tested so far, and they have a more neutral sound signature. On the other hand, the Audio-Technicas have better wireless range and are better-built than the Bose. They also have a great battery life but take much more time to charge fully. While the Bose SoundLink supports an earlier version of Bluetooth and therefore has worse wireless range, it can connect to 2 devices simultaneously, which the ATH-M50xBT can’t do, but they support Bluetooth 5.0.
