Built for Daily Listening

The XIAOWTEK A66 earbuds deliver wireless audio for commuters, office workers and fitness users who want a compact in-ear design without cables. Bluetooth 5.4 provides a stable link to phones, tablets and laptops, while passive noise cancellation reduces ambient sound during calls or music playback. Each bud weighs 4.5 g, keeping long sessions comfortable.

Battery Life and Charging

A single charge gives up to 8 hours of continuous play, and the case extends total runtime to 50 hours so you can go days between wall charges. Dual LED indicators on the case show remaining power for both buds and case at a glance. The IPX7 rating protects the internals from sweat, rain and light splashes during workouts.

Touch Controls and Accessories

Smart touch surfaces let you manage playback, volume and calls without reaching for your device, and the 13.4 mm graphene diaphragm drivers produce deep bass with clear mids and highs. Dual ENC microphones suppress 85% of background noise for clearer voice pickup. The package includes a charging cable and a user manual to get you started.

Questions about this item

How do I pair the XIAOWTEK A66 earbuds with my phone for the first time?

Open the charging case, remove both earbuds and they enter pairing mode automatically; select "A66" in your phone's Bluetooth 5.4 menu to complete the connection.

When will I need to replace the ear tips on the A66?

Replace the silicone tips when they lose their seal or show tears; a poor fit reduces the passive noise cancellation that blocks 85% of background noise during calls.

At what volume level does the 8-hour single-charge rating drop noticeably?

The 8-hour playback figure is measured at moderate volume; sustained high-volume listening will reduce per-charge runtime before the case needs recharging for the full 50-hour total.
