Sony Extra Bass BT Headphones

I am very pleased with these headphones. I am not all that demanding, but I do want reasonable bass and clear highs and mids and these do not disappoint. I have had these for a couple days, and I've been listening for about 5-6 hours each day to a variety of mostly rock and techno. My specific thoughts:Pairing: I paired these with my Moto X Pure (2015) Android phone via NFC, and it was exactly as seamless and quick as you could hope for; it was almost anticlimactic because I just put the phone up to my ear and 1.5 seconds later it said "phone paired". I also paired with my HP Envy Windows 10 Laptop, and it worked exactly as it should have.Battery: I have only had it for a short while, but right now it's holding up quite well; I didn't charge at all, just straight out of the box and I've logged probably 15+ hours of listening.Range: Pretty standard Bluetooth range - I can walk around the office and 25 feet away I'm still connected.Sound: I'm totally happy with all aspects of the sound on these things. I understand that these aren't $500+ headphones, but they sure sound great. These are on-ear headphones, but there isn't a whole lot of sound leaking in or out. I like the bass reproduction, and it totally doesn't wipe out/overpower the other sound ranges. It's quite crisp, and the volume is sufficient for any environment.Build Quality: I have no complaints here. They feel very lightweight, and hopefully that doesn't mean they don't break down the road but so far so good. I bought a cheap case for when I throw these in my work laptop case just to be prudent, of course. They don't feel like they're going to break, and nothing seems loose or in danger of falling off, but again I was surprised at how light they are so hopefully that's not a bad thing.Comfort: These feel good - I have an average to slightly larger than average sized head, and I can keep these on for at least a couple hours without chafing. You might want to take them off after several hours, but I don't know any headphones that you don't have to take off at least some of the time. I can feel a slight amount of quasi-suction on my ears, but nothing close to uncomfortable. They are, as I mentioned, lightweight, so there shouldn't be any problems with neck strain.Price: For about $75 you can't do much better. That's a bargain bin price, practically. For a name brand product you can trust, I'm very happy with the price.TL;DR - Definitely look into these if you want cheap, great sounding headphones that you can keep on for a few hours. The battery life is great, and there aren't any downsides that I've run across.
