Ultra-Light In-Ear Earbuds

AT&T SK18 in-ear earbuds weigh 0.08 ounces each and use a single-ear coupling for a discreet fit. Sound-isolation technology blocks ambient noise while the 32 ohm dynamic driver delivers audio. The glossy black finish keeps the profile low for work or sleep.

Side Sleepers and Commuters

The tiny housing suits small ear canals and side sleepers who need pressure-free comfort during long sessions. Touch controls manage playback and calls without reaching for a phone. Buyers who want over-ear headphones or a traditional stereo pair with a headband should look at other form factors.

30-Hour Case Battery

The 300mAh wireless charging case stores enough power for 30 hours of total listening after a 1.5 hour USB-C charge. Each earbud runs for 6 hours on its own and maintains a 10 meter wireless link. This single figure decides whether the daily routine fits between charges.

Questions about this item

What wireless standard do these earbuds use and what is the practical range?

The earbuds connect wirelessly via Bluetooth and maintain a stable link up to 10 meters from the source device.

What physical items are included for wearing and charging the earbuds?

The box contains two invisible earbuds, a wireless charging case and a USB-C charging cable.

How do you pair the earbuds for the first time and what common step is missed?

Open the charging case, remove both earbuds and select the model from your device's Bluetooth menu; the step often missed is taking both buds out together so they enter pairing mode simultaneously.
