Key Features

Audiophile tuning
Sennheiser’s in-house 42 mm transducer and refined acoustic design deliver a neutral audiophile sound with lifelike mids, stunning detail, and a wide, natural soundstage. 

High-resolution audio
Enjoy high-resolution wireless sound with support for aptX™ HD and aptX™ Adaptive, especially when paired with the included BTD 700 Bluetooth® USB C Dongle. For maximum purity, connect via USB C cable or analog input for lossless listening up to 24-bit/96 kHz. 

Parametric EQ
Expert-level equalization lets you define frequency bands, bandwidths, and filters to precisely shape your sound. Tailor bass, enhance vocals, or fine-tune for any genre. 

Crossfeed feature
Designed for classic tracks with hard-panned mixes, it takes instruments concentrated on one channel and balances them out, providing a more natural listening experience, similar to how the track would sound on your stereo system.  

Hybrid adaptive ANC
The powerful noise cancellation combines feed forward and feed backward ANC technology to block distractions without degrading clarity, dynamics, or balance. The adaptive mode automatically adjusts to the environment for optimal performance. 

Adjustable transparency mode
Low-noise microphones allow you to instantly hear surrounding sounds for improved situational awareness when you need to stay aware of your environment. 

Up to 60-hour battery
A class-leading battery lets you listen for days, not hours and keeps you going through long trips or work weeks. Just 10 minutes of fast charging adds up to 7 hours of playtime, ideal for when you’re on the move.

Refined acoustic architecture
Every part of the acoustic chain, from the transducer to the transparent acoustic mesh, and optimized back volume, works in harmony to produce smooth upper mids, detailed treble, and an open, and natural soundstage.  

Exceptional comfort
A lightweight build, low clamping force, generous earcups, and a premium Japanese leatherette headband ensure hours of fatigue-free listening.  

BTD 700 Bluetooth® USB C Dongle
The USB C dongle delivers high-definition audio for music lovers and gamers. Enjoy easy plug-and-play setup for seamless, reliable connectivity and versatile compatibility.
