Sennheiser MOMENTUM True Wireless 4 Earbuds

The Sennheiser MOMENTUM True Wireless 4 earbuds deliver crystal-clear sound through the TrueResponse transducer system and lossless audio technology. Bluetooth 5.4 connectivity supports LE Audio and Auracast for modern streaming. Adaptive ANC with Anti-Wind Mode isolates outside noise effectively. The Black Copper finish distinguishes this model from standard colour options.

Sustained listening with 30-hour battery life

A lithium-ion battery provides up to 30 hours of total playback time across the earbuds and charging case. Quick-charge functionality yields an hour of play from just 8 minutes of charging. The secure in-ear fit with extra-soft silicone tips maintains comfort during extended sessions. Multipoint connectivity keeps two devices linked without repeated pairing cycles.

Bluetooth 5.4 practical limits

Bluetooth 5.4 enables LE Audio and Auracast features where source devices and firmware support them. Standard Bluetooth range and codec negotiations apply in typical environments. Auracast broadcast audio requires compatible receivers and infrastructure not guaranteed on all platforms. Firmware updates unlock the full feature set advertised for this model.
