The Audio-Technica ATH-AC5TW is a true wireless open-ear earbud that hooks over the ear and leaves the ear canal uncovered, with 17 × 12mm oval drivers, Bluetooth 5.4 multipoint and up to 13h per charge (34h with the case). It suits walkers, commuters and office listeners who want to hear their surroundings while they listen.
Who the Audio-Technica ATH-AC5TW is for
Walks and commutes: The air-conduction, open-ear design leaves your ears uncovered, so you can still hear approaching cars and bikes, as Audio-Technica points out.
All-day wear: Each earbud weighs about 10.5g on an ear hook and runs up to 13h per charge, or up to 34h with the charging case.
Calls and hybrid work: Two MEMS mics with beamforming focus on your voice in noisy places, and multipoint keeps a phone and a laptop connected at the same time.
Low-volume listening: Dual Bass Enhancement Technology combines DSP bass reinforcement with a dynamic EQ that Audio-Technica tuned to keep bass present at low volume.
Light rain and splashes: The earbuds carry an IPX4 splash rating; the charging case is not rated.
Skip it if: you want noise cancelling, LDAC or volume control on the earbuds: codecs are AAC and SBC, the on-bud controls cover play/pause and answering calls, and the open design lets outside sound in.
