Sports earbuds with 16-hour battery

The SuperTooth U18 are wireless in-ear headphones built for workouts. Flexible earhooks and four eartip sizes keep them secure during running, hiking or gym sessions. Bluetooth 5.3 pairs quickly with smartphones, tablets and computers running iOS, Android or Windows. A lightweight 18.5 g frame adds minimal bulk.

IPX7 waterproof rating handles sweat and rain

The sealed shell and nano-coating protect internals from heavy perspiration and downpours. Eleven-millimetre dynamic drivers deliver deep bass and clear stereo for music and calls. The 32 ohm impedance works efficiently with the onboard battery, giving up to 15 hours of talk or music time and 16 hours standby per charge.

USB-C charging cable and clips included

A two-hour charge restores full capacity using the supplied cable. Cable and clothing clips keep wires tidy during activity. The set ships with four extra eartip pairs so you can fine-tune the seal. Smart-watch pairing is not supported, so buyers needing that link should look elsewhere.
