Let me start by saying these headphones have become my go-to for workouts. The bone conduction tech is legit - I can hear my surroundings while cycling, which is a safety must. The redesigned silicone finish? Super comfy, even with my helmet and sunglasses on.

But here's the real kicker: the dual-mode feature. Bluetooth for land, MP3 for swimming? Genius. I've taken these in the pool and the audio clarity underwater blew my mind. Though fair warning - switching modes requires ninja-fast button pressing that had me frustrated at first.

Battery life is... okay. I get about 4 hours of Bluetooth use (half the advertised time), but charging is lightning fast. The 8GB storage holds all my workout playlists, though loading audiobooks is more hassle than it's worth.

Now the downsides: Phone placement matters big time. Keep it in your jersey pocket or say goodbye to stable Bluetooth connection. And while the sound quality impresses at medium volume, max volume gets uncomfortably buzzy.

The fit could be better too - they tend to slip during intense movement. I've resorted to wearing a headband over them during winter runs.

Despite these quirks, I'm keeping them. Why? Unbeatable waterproof performance and H2O Audio's stellar customer service (they actually respond!). Just know what you're signing up for - amazing tech with some real-world compromises.
