The 2025 Accentum lineup debut is among the most affordable TWS earbuds from the specialist brand Sennheiser. The model is in an open-fit form factor, has an IPX4 water-resistant housing, a clean, minimal design (available in beige or black), and a lightweight (4 g) build. It uses 11 mm dynamic drivers that support an extended frequency range of 25 to 15,000 Hz and feature minimal harmonic distortion (up to 0.08%), contributing to clean sound that stays as close as possible to the creator’s intent.
The Sennheiser Accentum Open connect via Bluetooth v5.3 and operate at distances up to 10 meters, and they are equipped with a microphone, which makes them suitable for calls and other voice communication scenarios. You can adjust volume directly by touch (touch controls supported), and additional sound settings are available in the Smart Control app. Battery life is about 6 hours without the case and up to 24 hours with it. You can charge the case not only via USB-C but also wirelessly. Also note fast charging: a 10-minute cycle gives another 1 hour of music listening.
