Sanag B21S Open-Ear Bone Conduction Earphones Review

The Sanag B21S open ear bone conduction Bluetooth earphones make most sense on the walk to the station, a damp lunchtime run or a handsfree call while cooking, when keeping an ear on traffic, tannoy announcements or the front door matters. The black handsfree headband feels smooth and light against the skin, with no in-ear pressure, and the 10H battery is useful for longer days out. The trade-off is less sealed-in bass than conventional earbuds, but for practical listening across the United Kingdom, that feels fair.
