XIAOWTEK S66 Pro Wireless Earbuds, Bluetooth 5.4, LED Display, IPX7

For listening across a phone, tablet or laptop, the XIAOWTEK S66 Pro earbuds keep audio wireless and everyday controls close at hand. Their in-ear design pairs with a charging case that displays battery levels on an LED screen. Bluetooth 5.4, touch controls and a four-microphone ENC system support a convenient routine for music, calls and workouts.

Technical overview

The S66 Pro uses dynamic drivers with a 13 mm coil design for stereo playback, with bass that connects to the mid and high frequencies. Bluetooth 5.4 provides wireless connection to compatible devices, while the earbuds are listed as compatible with cell phones, tablets and laptops. Open the case for automatic pairing, then use the touch sensor to manage playback, adjust volume, change tracks, answer calls or access a voice assistant.

For calls, four microphones and ENC noise reduction are designed to pick up your voice and reduce surrounding sound. The case’s digital LED display shows the charge level for the case and earbuds, making it easier to check power at a glance. Each earbud is rated for up to six hours on a charge, with up to 50 hours of total listening time when using the charging case between sessions. The in-ear fit uses soft silicone tips, and the earbuds are rated IPX7 for water resistance.

Tips for day-to-day use

Keep the charging case with you to recharge the earbuds between listening sessions and make use of the stated total playback time. The LED display gives a quick indication of charge before a commute, work call or workout. Touch controls let you handle common playback and call functions from the earbuds, rather than reaching for your connected device.

For a video, a phone call or a playlist during exercise, the same pair can connect wirelessly to a compatible phone, tablet or laptop. The in-ear format and included silicone tip sizes let you choose a tip for your preferred fit. Customer feedback often highlights sound, quick Bluetooth connection and visible battery status. Opinions on fit and noise cancellation are mixed, so those experiences can vary, the four-mic ENC feature is specifically described for voice calls.

Included in the pack

The pack contains two Bluetooth earbuds, a charging case, a USB cable, a user manual and three pairs of eartips. Having several tip sizes provides a practical way to tailor the in-ear fit, while the case serves as both a place to store the earbuds and a source of additional charges.
