Audio-Technica ATH-M50xBT2

The M50x cut loose from its cable — reviewers hear a balanced, sharply imaged wireless monitor; the arguments are over its clamp, its seal and how well it holds up.

Audio-Technica ATH-M50xBT2

The short version

What to know.

A closed-back Bluetooth version of the ATH-M50x that reviewers broadly agree sounds balanced and close to neutral. RTINGS calls the profile very neutral and less bass-heavy than the first M50xBT, and most editorial reviews call it balanced with a slight warm lift; whether it differs much from the wired M50x is disputed. Imaging and detail draw near-unanimous praise. The battery is rated at 50 hours and lasts 55–65 in testing, and wired and Bluetooth playback measure the same. The bass divides by direction: most hear it tight and well judged, some hear a bump that's a bit too much, and others want more sub-bass. A few hear sibilance in the treble. Four things split outright. Comfort is long-session easy for most, but a clamp-and-heat complaint persists. Isolation is excellent to studio users, while RTINGS measured it as poor against engine rumble; the mic's sidetone is also on by default and can only be switched off in the app. The press calls the build solid, while owners report flaking pads, creaky hinges and connection glitches. The soundstage is natural to some and narrow and closed to others. Value is broadly good at its usual street price, with the lack of ANC the main caveat.

About this product

The second Bluetooth version (2021) of the ATH-M50x studio monitor: the same 45 mm closed-back, foldable design with Bluetooth 5.0, LDAC/AAC/SBC, USB-C charging, a companion app with EQ, and a 3.5 mm input for passive wired use. Not the 2018 ATH-M50xBT (micro-USB, aptX, touch-sensitive cup) nor the wired ATH-M50x. Limited colourways such as Lantern Glow and Ice Blue share the hardware.

Audio-Technica's ATH-M50xBT2 is the second wireless take on the ATH-M50x, the closed-back studio monitor that became one of the best-selling headphones of the 2010s. It keeps the same 45 mm drivers, folding and swivelling frame and pleather pads, and adds Bluetooth 5.0 with LDAC, a companion app with EQ, USB-C charging, a microphone and a 3.5 mm input for wired use. There is no active noise cancelling.

The sound gets warm reviews: balanced, close to neutral and sharply imaged, and RTINGS measures it as less bass-heavy than the first M50xBT. How far it moved from the wired M50x is itself debated. The bigger arguments are about the old frame: how hard it clamps, how warm the pads get, how much outside noise it blocks, and how well the plastics and electronics last in owners' hands.

A good fit for

  • Listeners who want the M50x's monitor heritage in a balanced, close-to-neutral wireless headphone
  • Long days away from a charger — rated at 50 hours, it lasts 55–65 in testing
  • Home studio, guitar practice and DJ-style use where a sealed fit and a wired fallback matter
  • Anyone who prizes imaging and detail over a big, open stage

Think twice if

  • You commute by bus, train or plane — there's no ANC, and RTINGS measures poor isolation against engine rumble
  • You wear glasses or have a larger head and listen for hours — the clamp and warm pleather pads bother a sizeable minority
  • You want a wide, open soundstage — several reviewers find it narrow and closed
  • You expect premium materials or years of trouble-free use — owners report flaking pads, creaky hinges and connection glitches
  • You want LDAC hi-res with EQ — the app caps LDAC at 48 kHz once EQ is on

The reviewer consensus

Agreement &
disagreement.

4 / 12topics divide opinion
3 Strong agreement5 Mostly agree4 Divided opinions

Common ground6

  • Balanced and close to neutral, with a slight warm lift — and less bass-heavy than the first M50xBT, by RTINGS' measurements.
  • Imaging is a standout: panned instruments sit distinctly, even where the stage feels small.
  • Detail is strong for the price — small nuances and recording flaws come through.

Points of contention5

  • Comfort: 'comfortable for hours' vs 'clamps and runs hot' — the old M50x frame's fit depends on head size, glasses and session length.
  • Isolation: 'excellent passive seal' vs 'poor against rumble' — studio rooms vs streets and buses, plus a sidetone that is on by default.
  • Build: 'solid and tough' to reviewers vs 'plasticky and failure-prone' to many owners — flaking pads, hinges, sockets and glitches show up with time.

Broad agreement: balanced and close to neutral, with a gentle warm lift in the bass, and owners mostly agree. RTINGS measures it as less boomy than the gen-1 M50xBT. Comparisons with the wired M50x split: GearUP hears it gone almost neutral, while StereoNET, Mixdown and a 2026 Reddit owner hear almost no difference. StereoNET notes a 'cheeky' mid-bass hump, and Les Numériques measures a subtle W shape.

“Their sound profile is very neutral and not as boomy or bass-heavy as the original Audio-Technica ATH-M50xBT.”

RTINGS

“The basic sound of the second generation is characterised by an excellent balance with a very clean, pure sound image, which merely has a subtle, warm finish.”

headphonecheck.com (Maike Paeßens)

“Sonically the faithful neutrality and cheeky mid/bass hump is still there.”

StereoNET (Matthew Jens)

Measured

On RTINGS' rig, after normalising at 500 Hz, it sits within about ±3 dB of RTINGS' own target from 50 Hz to 3 kHz: +3 dB at 100–150 Hz, −4 dB at 300 Hz and a −4 dB notch at 4 kHz. Against the same rig's HD 650 it carries +4.5 dB at 100 Hz and −5 dB at 300 Hz. SoundGuys finds the response 'pretty conservative', and RTINGS' 2023 retest found wired and Bluetooth, and SBC and LDAC, identical.

Limitations & method.

As of

What to keep in mind 5

  1. This is a read of where opinion lands as of November 2026. The BT2 launched in 2021 and its firmware and app have been updated since, so some early complaints may no longer apply.

  2. Fit drives most of the disagreement: the clamp, the pads' depth and warmth, and the seal vary with head size, glasses and pad wear, which moves comfort, isolation and even bass quantity.
