[Update 16 months of use. Still love them.]I am a huge fan of bone conduction headphones, mostly because I work in an office in a position where I have to be able to hear the world around me, and I have a jogging route I like that's along a road, but they never sat quite right on my head and would start bugging me after awhile. Recently I bought a pair of "true wireless" earbuds and fell in love with the convenience and lightweight feel, but I never really liked the feeling of stuffing them into my ear, especially over long periods of time. And obviously they couldn't take the place of my headphones because they blocked sound.These take the best of both worlds. They aren't bone conduction so it doesn't need contact with your head; it's more like having tiny speakers that whisper into your hear. I can hear the world around me, I can hear my music perfectly, and the world around me can't hear my music so I'm not bothering my coworker sitting six feet away from me. They're light enough that they sit on my ears comfortably, such that I've forgotten I've had them in until I walk away from my phone and my music stops. It took some getting used to, I think. For a few days they felt like they were pinching something in my ear on one side but that went away.I should say, I am not an audiophile by any definition of the word. Also I'm listening to a lot of lo-fi music while I work. That said, they sound great to me. Your mileage may vary.Negatives: 7 hour battery life is not quite enough to get me through a workday, but if I charge them during my lunch hour it's not a problem, and if I forget, I can still leave one side charging and the other side playing. The case is also bulkier than most true wireless earbuds. I get that these have a much wider profile, so it's necessary, but I would like to see if they could make a the case a little thinner in future iterations. But the headphones fit nicely into the case via magnet and the lid magnetically closes nice and tight.I'd say, if you need this, you know you need it. I'm very happy with these.Edit: three months in these are still my go-to. They're so light I still forget I have them on sometimes. No earphone tips that get dirty and need to be cleaned is also a plus. Battery life is still an annoyances sometimes and it'd be great if there was a button that let you disconnect from the phones instead of through the device. There's still nothing on the market today that I would swap these for.[Update 16 months or so]These are still going great. Right now I'm using them primarily in the office. I bought a second pair of similar but cheaper wireless earphones: one thing I noticed with the cheaper ones there's more audio bleed. Like I can wear these and no one around me is going to hear my music, as if it's going straight into my ear. The cheaper ones are more like tiny speakers near my ear. They have more batteries life but I still prefer Acreo brand ones for sound quality and privacy.These have also been unexpectedly good for traveling in e.g. subways, airports, etc. because I can hear my music but I can also hear around me. I just have better spatial awareness with these vs in-ear earbuds.Hoping we see an update from Acreo sometime. These have been pretty nice.
