The Sennheiser ACCENTUM Open is a lightweight open-fit true wireless earbud with 11mm dynamic drivers, Bluetooth 5.3 multipoint and IPX4 splash resistance, offered in Black, Cream or Blush. It suits people who find sealed ear tips uncomfortable and want to keep hearing the world around them.
Who the Sennheiser ACCENTUM Open is for
Comfort-first listeners: The stem design rests in the outer ear without sealing the ear canal, and each earbud weighs about 4.35g.
Staying aware outdoors: The open fit lets surrounding sound through, and you can wear just one earbud when you need more awareness.
Phone and laptop users: Multipoint keeps two devices connected at once, and the earbuds remember up to 8 paired devices.
Calls and quick breaks: Two beamforming microphones per earbud use AI-based noise reduction for calls, and Smart Pause stops playback when you take an earbud out.
Skip it if: you want noise canceling or app controls; Sennheiser built the ACCENTUM Open without ANC and without app support.
