Momentum True Wireless 5 Earbuds

The batteries in the Sennheiser Momentum True Wireless 5 can be replaced at home. Both the earbuds and the charging case open with a screwdriver, and a battery replacement tool comes in the box.

That matters because the cells are small. Each earbud holds a 72 mAh lithium-ion battery, and the case holds 760 mAh. Here the battery is a part that can be swapped. The earbuds play for up to 12 hours with noise cancellation off and up to 6 hours with it on, and the case stretches total playtime to up to 40 hours.

The sound side is built to match. Each earbud has a 7 mm TrueResponse dynamic transducer covering 5 Hz to 21 kHz, fed over Bluetooth 6.0 class 1. Codecs run from SBC and AAC up to aptX Adaptive, with a 24-bit/96 kHz high-resolution option, and aptX Lossless at 16-bit/44.1 kHz. The Smart Control Plus app adds an 8-band graphic equaliser and Sound Personalization developed with the Fraunhofer Institute.

Calls get four microphones in each earbud, one of them a bone-conducted voice accelerometer. AI and beamforming use them to isolate the wearer's voice. Noise cancellation is hybrid and adaptive, with anti-wind and Natural Transparency modes.

The earbud shape came from extensive in-ear scans, and silicone tips come in XS, S, M and L. The case charges at up to 5 W over USB-C, with no Power Delivery, or by Qi 2.1 wireless. Only the earbuds carry the IP54 rating, so the case should be kept away from splashes. Designed in Germany.
