Built for wireless listening

The Sennheiser M2 AEBT Black is a circumaural headphone that uses Bluetooth connectivity so you can listen without a cable. A 3.5 mm audio cable is also included for wired use with non-Bluetooth devices. The package supplies a USB charging cable, an inflight adapter, manuals and a carrying case for storage.

Thermals noise and power

Passive operation presents a 28 ohm impedance while active mode raises it to 480 ohms. The internal battery delivers approximately 3 hrs of wireless operating time before recharging. Total harmonic distortion stays below 0.5 % across the 16 Hz to 22 kHz frequency range.

Deciding specification

Sensitivity reaches 113 dB S.P.L. at 1 kHz, which determines how loud the headphones play from a given source level. The closed circumaural design with leather headband and earpads provides physical isolation rather than active cancellation. Buyers who need longer battery life or active noise cancellation should consider other models.

Questions about this item

How do I pair the headphones using NFC, and what step is often missed?

Enable NFC on your device, then tap it against the left ear cup until the Bluetooth indicator flashes; the step people miss is holding the device steady for a full second until the tone confirms pairing.

Which parts will need replacement after extended use?

The leather ear pads and headband cushion wear over time; the rechargeable battery will also lose capacity after many charge cycles.

What is the first limitation you hit during a long listening session?

The battery lasts approximately three hours per charge, so playback stops unless you plug in the included 1.4 m audio cable.
