Okay, so I've been using these Shokz OpenRun (formerly Aftershokz Aeropex) for about 3 weeks now and WOW - they're literally glued to my head 24/7.
First off, the open-ear design is GENIUS. I can finally hear my gym crush asking to work in while still jamming to my workout playlist. No more awkward 'huh?' moments when someone talks to me mid-set.
The battery life? Lies. Beautiful lies. Advertised as 8 hours but mine lasted through two back-to-back gym sessions AND my commute home. The 'low battery' voice warning is kinda annoying though - sounds like a robot begging for mercy.
Sound quality surprised me - it's like having tiny concert speakers attached to your face bones. Bass heads might complain, but honestly? I'll trade some thump for being able to hear traffic when I'm running outdoors.
Pro tip: Skip the included earplugs and use your own. The vibration takes getting used to - first time it happened I thought I was having a spiritual experience.
10/10 would recommend to anyone who wants to stay aware while working out. Just don't expect club-level bass and you'll be golden.
