How they differ in real use
Both are purpose-built sleep earbuds rather than daytime buds adapted for bed, both work without a subscription, and both store masking sounds on the buds so they keep playing after your phone disconnects. Both also have a private in-ear alarm that wakes only the wearer and some form of sleep tracking. The differences are in size, noise control and battery. The Ozlo Sleepbuds 2 weigh 1.6 g per bud and stand about 11 mm tall, which Gizmodo described as shorter and flatter than the A30; Gizmodo also found them comfortable for side sleeping. The Sleep A30 is roughly 2.4-3 g per bud, though SoundGuys still reported that it stayed in place overnight without pillow discomfort. On noise, the A30 has Smart ANC aimed at low-frequency sound, plus a case that listens for snoring and adjusts its masking audio in real time. The Ozlo has no ANC; it uses passive silicone tips and more than 50 masking sounds, and a Fast Company reviewer cited by SoundGuys found AirPods Pro 2 blocked snoring better. Battery favors the Ozlo: up to 14 hours per charge, against Anker's 7-9 hour rating for the A30 with ANC on (SoundGuys measured about 7.5 hours), rising to 16 hours only with ANC off. The A30 counters with Bluetooth 5.4, a USB-C case holding about 45-50 hours, and a lower price than the Ozlo's $279 list. SoundGuys found the A30's touch controls unreliable; the Ozlo's case adds a physical button for sleep sounds and alarm snooze.

Common questions
Do the Ozlo Sleepbuds 2 have noise cancelling?
No. The Sleepbuds 2 block noise passively with silicone ear tips and cover it with built-in masking sounds. Ozlo argues ANC is less effective against unpredictable sounds like snoring. If you want active noise cancellation in a sleep earbud, the Soundcore Sleep A30 has it.
Which lasts longer overnight, the Ozlo Sleepbuds 2 or the Soundcore Sleep A30?
The Ozlo Sleepbuds 2, rated at up to 14 hours per charge. Anker rates the Sleep A30 at 7-9 hours with ANC on and up to 16 hours with ANC off, and SoundGuys measured about 7.5 hours with ANC on. If you sleep with ANC enabled, the Ozlo is the safer bet for a long night.
Which is more comfortable for side sleepers?
On paper, the Ozlo Sleepbuds 2: at 1.6 g and about 11 mm tall they are lighter and flatter than the Sleep A30's roughly 2.4-3 g buds. Reviewers found both comfortable on a pillow, though, so ear-tip fit matters as much as size; try every included tip size for a full night.
