Designed for Side Sleepers

LORDWORLD M51 Sleep Earbuds are lightweight in-ear headphones shaped to hug the inner ear curve so they stay comfortable when you lie on your side. Each bud weighs 3.0 g and connects via Bluetooth 5.4 with one-step pairing up to 12 m away. A compact charging case with an LED power display provides 58 hours of total playtime and charges via Type-C.

Suits Light Sleepers and Commuters

These earbuds suit people who want barely-there earbuds for overnight use, travel or quiet offices where ambient noise reduction without active beeps is preferred. Touch controls on both buds handle playback, volume, calls and voice assistant. Buyers who need active noise cancellation, transparency modes or high-codec audio streaming should look at other models.

Battery and Connection Headroom

The buds alone deliver 5 to 7 hours of listening per charge while the case extends that to 58 hours, covering several nights or a long journey without a socket. Bluetooth 5.4 keeps audio and video in sync within the 12 m range. Extended sessions beyond 7 hours per bud or environments demanding certified water resistance will exceed the design limits.
