This was a gift for my daughter, and she loved them. I got them to go inside her helmet she wears skiing.

Great sound

I found these to be pretty sweet little speakers. They slip into and out of the pocket on my helmet easily, and they're easy to use. The Bluetooth pairing was easy to do, although both speakers needed to be out of the charger. You cannot do the initial pairing while either of them is still in the charger. Another tricky bit is that the speakers have a little plastic protector on the charging port (see photo). I didn't notice this at first.
I thought the sound quality was good. It wasn't overly tinny or too low. People who are used to a lot of extra bass would probably find that lacking here. But listening to music that I'm familiar with, it sounds good. The only downside is that since these aren't in-the-ear, other people can here them and that might be annoying to them. But then you don't have to worry about earbuds falling out and getting lost. Having them in a helmet muffles them a lot though. The seem to hold a charge well. They also seem pretty durable.
I like the case - it's slim and no larger than necessary. It fits in all kinds of pockets. It's nice that it gives you an indication of the battery level, but it's pretty minimal - high, medium, and low.

The product I never knew I needed (or existed). These are so cool!! I've not used them for snowboarding, but their application is so much more versatile than that!! My car was stolen, so I walk or bike pretty much everywhere when I'm by myself. These slip right into hats, or even into fuzzy headbands which is... amazing! My primary bike helmet already has Bluetooth, but sometimes I don't feel like fussing with it... so putting these into my headband, I can put the headband on & then put the basic helmet over it, or I can just throw the headband on while I'm walking. Either which way, it's great. Obviously, they do have to be removed to charge, but that's what I'd expect.

I wish I had known such a thing existed, but I'm happy to own these. I was previously using my air pods for walking, but I felt like... even if I'm not biking, I still want to be able to kind of hear what's going on around me... these work much nicer, I feel safer and more aware of traffic & other people which, where I live, is really important.

Easy to connect. No fuss. Great battery life for the way that I use them. Have not had them give out on me on any of my roundtrips thus far. I think the sound is wonderful. Haven't had any droppage issues with my phone unless the service drops but that has nothing to do with the headphones.

For my application, these are wonderful. And for my pleb ears, they sound great. I am not one to really recognize a big... what I am saying is, I am not a harsh critic about sound layers or whatever. Things sound good to me, or they do not sound good. Something is easy to use, or it's a pain & I won't use it. These sound good and are easy for me to use. I feel no need to try and upgrade - these are wonderful, and I'll continue using them for as long as they will work!

Works great, just as advertise. The buttons and controls are super easy to use on the mountain.
