I've been looking around for a good deal on bluetooth headphones and found these at a discount on Rank Booster, so I could give an honest review of them. And I've been happy with them. I was surprised at how they paired up with my phone so easily and quickly, and how they've maintained the pairing after being turned off and back on many times. At first I felt like they were kind of big, but what I do like is that the earpiece is angled to fit nicely in my ear, and they come with a variety of sizes of rubber earpieces and holders. You can pick from a couple different kinds of in the ear holders, or the over the ear holders, or none at all.
So they're comfortable and have good sound. There are volume controls on the one side, which is nice. My only complaint is that I wish the cord were longer. They aren't magnetic, but there's a little holder that I think is for holding them together around your neck when not in use. But for me, when I wear them around my neck, the ends don't reach each other so I can use the little holder. But I've got a fat neck, so for someone thinner, they're probably fine.
All in all, this is a nice set of bluetooth headphones/headset. I'd recommend it. I've been using them for about a week now, about 40 minutes a day, and haven't had to charge them. And I also haven't had to re-pair them with my phone. When I turn them on, it picks up the bluetooth connection right away. I know that sometimes that's an issue with bluetooth headphones.
