Podcasts at bedtime are simple when you live alone. Sharing a bed or a hotel room changes the problem. Earbuds can work loose overnight, and a speaker on the nightstand fills the whole room. The baseus sleep sk1 speaker offers another route.
The SK1 is a pillow speaker designed to sit under the pillow. It sends audio through the pillow to the sleeper’s ear, and Baseus says the sound stays close to the head.
Earbuds are not the only way to listen privately, and Bose has rethought fit and comfort for everyday wear. Bose’s next-gen earbuds for active lifestyles offer a useful comparison point.
How the pillow carries sound
Baseus calls the method micro-vibration conduction. Two vibration units push audio into the pillow, and the pillow passes it along to the head. The pillow effectively acts as the speaker cone.
The design depends on distance. Sound fades as the head moves away, and Baseus says it dies out before reaching the other side of a bed. The Gadgeteer reports that lifting the head reduces the volume noticeably.

Design and controls of the baseus sleep sk1 speaker
Reviewers describe the SK1 differently. Baseus-focused coverage calls it two circular pods joined by a narrow, curved bridge. The Gadgeteer calls it a flat bar.
The measurements are consistent across sources. The body is 16.5 by 4.5 by 1.4 centimeters, about 6.5 by 1.8 by 0.55 inches. It weighs 44 grams, or roughly 1.55 ounces, and the shell is 14 mm thick.
Three physical buttons sit along the edge of one pod. A small digital display on one end shows the time, the active mode and the remaining battery. You can check the time without reaching for your phone, though the display is hidden if the speaker sits under a pillow.

Sound options, alarms and battery
The companion app offers more than 100 tracks, including rain, campfire, ocean waves, birdsong and ASMR. Users can set a sleep timer from 30 to 120 minutes. They can also program up to 10 alarms.
Baseus says the alarms use the same directional path as the music. The company claims that the person beside you should stay asleep while you wake up.

The SK1 uses Bluetooth 6.0 and can play audio without a connected phone. A 300 mAh battery is rated for more than 10 hours of playback. A full charge over USB-C takes about two hours. None of the sources report independent battery tests, so these figures remain Baseus’s claims.

Pillow limits and price
Pillow thickness matters. Baseus recommends pillows up to about 8 cm, or roughly 3 inches, thick. For thicker pillows, or when sleeping on your back, the company advises raising the volume. The Gadgeteer also advises against the SK1 for thick memory-foam pillows.
JD.com lists the SK1 in China at 184 yuan. Conversions vary. The Gadgeteer puts the price at about $26, while iXBT estimates about $28.
The Gadgeteer reports a regional subsidy price as low as $24 in parts of China. No US or Amazon listing appears in the sources.
Who should consider it
The SK1 suits a narrow group. As an under pillow speaker, it fits someone who shares a bed, falls asleep to audio and dislikes sleeping in earbuds. At about $26 in China, it is a low-cost way to test the idea.
Battery life and charging speed matter even more for a device that stays under your head all night. Sharge’s compact, affordable Flow Mini 2 charger shows what budget-friendly charging can look like.

No source in this set reports an independent test of sound isolation, comfort or battery life. Whether a podcast stays clear at the pillow while staying quiet for a partner remains untested. Those results will decide whether the SK1 earns a place on the nightstand.
