Sennheiser ACCENTUM Open

Open-type true-wireless earbuds: they rest in the ear without sealing it, so your own footsteps, colleagues, and traffic stay audible while the music plays over the top.

They suit the office, the school run, and runners who need to hear the street — and anyone whose ears simply reject silicone seals. All-day comfort is the entire pitch.

Physics collects its fee: an open fit means modest bass and zero isolation, and there is no noise cancelling to summon. Wrong product for aeroplanes; exactly right for staying present.
