Audio-Technica M-Series and Wireless: 6 Wired, 5 Bluetooth

Of the 11 Audio-Technica headphones we read on its US site on 7 November 2026, six are wired M-Series studio monitors and five are Bluetooth. All five Bluetooth models list two-device multipoint, and two of them give battery times with noise cancelling on.

The set is Audio-Technica’s M-Series page (six wired models and two wireless ones) plus the three other wireless headphones on its US Wireless listing that are not earbuds or headsets. A-T sells more headphones than this, including the R-Series and other open-back models, so this is not the whole catalogue. Every figure is A-T’s own, from each product page’s Features list and Specification Table.

The six wired M-Series models

Model	Fit	Driver	Impedance	Frequency response	Weight	Cable
ATH-M70x	Over-ear, closed	45 mm	35 ohms	5–40,000 Hz	280 g	Detachable, 3 included
ATH-M60xa (affiliate link to Amazon, opens in a new tab)	On-ear, closed	45 mm	38 ohms	15–28,000 Hz	220 g	Detachable, 3 included
ATH-M50x (affiliate link to Amazon, opens in a new tab)	Over-ear, closed	45 mm	38 ohms	15–28,000 Hz	285 g	Detachable, 3 included
ATH-M40x	Over-ear, closed	40 mm	35 ohms	15–24,000 Hz	240 g	Detachable, 2 included
ATH-M30x	Over-ear, closed	40 mm	47 ohms	15–22,000 Hz	220 g	Fixed, 3.0 m
ATH-M20x	Over-ear, closed	40 mm	47 ohms	15–20,000 Hz	190 g	3.0 m, detachable not stated

Weights are A-T’s, without cable. The split by driver size is clean: the three higher-numbered models use 45 mm drivers and the three lower-numbered ones use 40 mm. The impedances sit between 35 and 47 ohms, and A-T says the M60xa’s “low-impedance design delivers high output level from any headphone output”.

A-T’s own wording separates them further. It calls the M70x the “M-Series flagship model”, tuned for “extremely accurate reproduction”. The M50x is the one it credits with “deep, accurate bass response”. The M40x is “tuned flat”, the M30x “for enhanced detail, with excellent mid-range definition”, and the M20x “for enhanced low-frequency performance”. Those are A-T’s descriptions of intent, not measurements.

The M60xa is the one on-ear model of the 11 and the one on A-T’s On-Ear listing. It uses the same 45 mm driver size, 15–28,000 Hz range and 38 ohms as the M50x, at 65 g lighter. Note that A-T’s web address for it still reads ath-m60x.

The five Bluetooth models

Model	Fit	Driver	Battery, A-T’s maximum	Codecs	Bluetooth	Weight
ATH-M50xBT2	Over-ear, closed	45 mm	About 50 h	LDAC, AAC, SBC	5.0	307 g
ATH-M20xBT	Over-ear, closed	40 mm	About 60 h	AAC, SBC	5.0	216 g
ATH-AL5NC	Open-back	53 mm	About 50 h noise cancelling on, 75 h off	LDAC, AAC, SBC	5.3	240 g
ATH-S300BT (affiliate link to Amazon, opens in a new tab)	Closed	40 mm	About 60 h noise cancelling on, 90 h off	AAC, SBC	5.1	258 g
ATH-S220BT	Closed	40 mm	About 60 h	Not stated	5.0	180 g

All five list multipoint for two devices, a low-latency mode for video and games, and a 1.2 m cable in the box for wired listening. Two list LDAC; our codec explainer covers what that badge does and does not promise. How two-device mode interacts with codecs varies by maker, which our multipoint piece works through for Sony.

The two Bluetooth M-Series models carry the wired versions’ sound, by A-T’s account. It says the M50xBT2 delivers “the same critically acclaimed sonic performance as the original ATH-M50x” and the M20xBT “the same sonic signature as the wired ATH-M20x”. The M50xBT2 page also lists an AK4331 DAC and a dedicated headphone amp.

Which ones cancel noise

The ATH-S300BT lists “digital hybrid noise-cancelling technology” and a hear-through mode, and it is the one headphone of these 11 on A-T’s Noise-Cancelling listing; the other seven items there are earbuds. A-T gives the S300BT 60 hours with noise cancelling on and 90 with it off.

The ATH-AL5NC is harder to place from A-T’s own pages. Its Features list calls the function “noise reduction”, available over both wireless and wired connections, while its Specification Table gives battery times with “noise cancelling on” and “off”. A-T’s Noise-Cancelling listing does not include it. It is also the one open-back model here, and A-T says its open-back housings “improve airflow and reduce heat”. Our explainer on how noise cancelling works covers why fit matters alongside the electronics.

The ATH-M50xBT2, ATH-M20xBT and ATH-S220BT give one battery figure with no noise-cancelling mode, and none of the three is on the Noise-Cancelling listing.

Questions people ask

What is the difference between the ATH-M40x and ATH-M50x?

The ATH-M50x has 45 mm drivers and lists 15 to 28,000 Hz at 38 ohms; the ATH-M40x has 40 mm drivers and lists 15 to 24,000 Hz at 35 ohms. A-T says the M40x is tuned flat. The M50x comes with three detachable cables, the M40x with two.

Which Audio-Technica headphones are wireless?

Of the 11 we read, five: the ATH-M50xBT2 and ATH-M20xBT from the M-Series, plus the ATH-AL5NC, ATH-S300BT and ATH-S220BT. All five include a 1.2 m cable for wired listening as well.

Do Audio-Technica headphones have noise cancelling?

The ATH-S300BT lists digital hybrid noise cancelling, and A-T’s Noise-Cancelling listing includes it. The open-back ATH-AL5NC lists a noise-reduction function and battery times with noise cancelling on. The other nine models here do not list it.

Is the ATH-M50xBT2 the same as the ATH-M50x?

A-T says the M50xBT2 delivers the same sonic performance as the wired M50x, and both list 45 mm drivers, 15 to 28,000 Hz and 38 ohms. The M50xBT2 adds Bluetooth 5.0 with LDAC, 50 hours of battery and multipoint, and weighs about 307 g against 285 g.

Which Audio-Technica M-Series headphones have a detachable cable?

The ATH-M70x, ATH-M60xa, ATH-M50x and ATH-M40x list detachable cables. The ATH-M30x lists a fixed 3.0 m cable, and the ATH-M20x page gives a 3.0 m left-exit cable with no detachable row.

Is the ATH-M60xa on-ear or over-ear?

On-ear. A-T describes a low-profile, closed-back, on-ear design, and it is the one model of these 11 on A-T’s On-Ear listing. It shares the 45 mm driver size, frequency range and 38-ohm impedance of the ATH-M50x.
