Ultra-Small In-Ear Fit

These SuperTooth SK18 earbuds weigh 0.08 ounces each and measure roughly the size of a peanut. The tiny housings sit completely inside the ear canal for a nearly invisible profile. They suit commuters, office workers and side sleepers who want audio without a visible stem or bulk.

Bluetooth 5.3 and Case Compatibility

Pairing requires a source device that supports Bluetooth 5.3 for the advertised low-latency link. The tumbler-style charging case stands upright on a desk but measures 14.33 by 12.83 by 9.06 inches, so verify drawer or bag space before ordering. The case shows remaining capacity through an LED display.

Plastic Build and Touch Controls

The glossy plastic shells resist light splashes thanks to a waterproof coating, while the in-ear tips provide passive sound isolation. Tap gestures on each bud handle calls, volume, voice assistants and playback without reaching for a phone. A full recharge takes one hour and yields four hours of listening, with the case extending total use to 24 hours.
