The verdict
The Ozlo Sleepbuds successfully carry the torch from their Bose predecessors while adding valuable features like custom audio playback - but at $299, they're asking for a premium investment in your sleep.
✓Liked: Comfortable and compact, Can play custom audio, Good passive isolation, Battery life
✕Could be better: Expensive, No sleep tracking (yet), No ANC, Long pairing process
