Reviews on these are mixed at best so I figured I'd give it a shot. I have spent at least 4k on headphones from Beats to Bose to AKGs. The only thing I've never really had would be any of the newer Apple products as I've always used something android. With that out of the way these are hands down, the best open ear bone conducting headphones I've ever used. Do they beat any decent wired in ear bud in this price point at sound, absolutely not. Do they compare to comparatively priced references headphones, again, no. Where these excel however is in the very specific niche of people requiring open ear headphones for potential strenuous and or dangerous activity. In my line of work, these are indispensable for the ability to seamlessly speak with important parties while staying alert and hands free. Now, you could accomplish that with any bone conducting headphones but as I've owned multiple pairs of shockz, previous Philips bc headphones and a few other brands all in the over $100 range and I have to say these deliver the best sound quality and volume I've ever had. They also offer superior sound quality with the speakers from what I've been told to most other brands I've used. The light in the rear for me is also a great feature as I'm often on bike trails either running or cycling into the late hours and between being able to hear bikes behind me and the fact that they can see me, I feel so much safer, especially if I find myself riding on the road for a few seconds ( I could just buy a rear light but with this, that's one less thing to charge) . The only real negative I have for these is that stupid charging port. The previous generation used the same charger as my Android. I suppose this might save a sliver of internal space but I'd prefer it just be wider if it meant I didn't need to keep track of a special cord. Still, so far, there's nothing else that can check off all the boxes for me like this. If you're just an audiophile listing to your favorite music, pony up about $300- 320 for some decent reference headphones, an audio port adapter for you phone and an amp. If you're just gonna be in the gym and you're using apple products, I imagine your air pods are better. If you're gonna be outside and you need to keep your head on a swivel most of the time or you're even gonna be speaking with people while potentially otp or listening to music, I would strongly recommend these.
