XIAOWTEK S66 Wireless Earbuds with Bluetooth 5.4, LED Display and IPX7

For a workout, commute or video call, the XIAOWTEK S66 wireless earbuds give you in-ear audio with touch controls and a charging case that displays its power level. Bluetooth 5.4 provides a wireless connection to compatible devices. The case’s LED display makes charge levels easy to check at a glance. A four-microphone ENC system is designed to help keep your voice clear on calls.

Key points

The S66 pairs Bluetooth 5.4 connectivity with an in-ear design for listening from a cell phone, tablet or laptop. Open the charging case to begin pairing, then use the touch controls to manage playback, adjust volume, skip tracks, answer calls or access a voice assistant. That keeps everyday controls close at hand without needing to reach for your device each time.

For music, the earbuds use 13 mm dynamic drivers and support AAC and SBC audio codecs. The charging case has a dual digital LED display showing the power level of the case and earbuds, so you can see their charge status while preparing to head out. The earbuds are rated IPX7 waterproof, making them suited to workout use and other active routines. The four-microphone ENC setup is intended to reduce background noise picked up during calls.

Getting the most from it

Pair the earbuds with a Bluetooth-enabled phone, tablet or laptop for music, calls and video. When watching shows or playing games, the Bluetooth 5.4 connection is designed for low-latency audio, helping sound stay in sync with what is on screen. The stated Bluetooth range is 15 metres, which can make listening more flexible when your connected device is nearby.

For a more secure in-ear fit, choose from the three pairs of included eartips. The case recharges the earbuds between listening sessions, while its LED display lets you check the remaining power before leaving home. The package also includes a USB cable and user manual. The earbuds can be used in turn with the case for up to 50 hours of total playtime, according to the product details.

Who it’s for

These earbuds suit people who want one wireless pair for calls, music and everyday listening across a phone, tablet or laptop. The touch controls are useful when moving between tracks or answering calls without handling the connected device, while the in-ear shape and selectable eartips support a closer fit for workouts and travel.

They’re also worth considering if call handling is part of your routine: four microphones with ENC are designed to focus on your voice and reduce surrounding noise. Compared with choosing separate earbuds for calls and casual listening, the S66 brings those uses together with a charging case and a visible power display.

Buying verdict

Choose the XIAOWTEK S66 if you want Bluetooth earbuds that combine touch-operated playback and call controls, a case with an LED power display, and an IPX7 waterproof rating for active use. The 13 mm dynamic drivers support everyday music listening, while the microphone system adds a practical call feature. With support for cell phones, tablets and laptops, they’re a useful fit for moving between work, entertainment and workouts with one pair.
