I got a pair of these with a Bluetooth NBN-DS200 headset. Before then, I had used a pair of standard Sony Ericsson earbuds and I thought the sound quality was OK. Using an exsiting pair of high Quality Sony EX earbuds the sound was much better. But with these it's even more impressive. Don't expect the earth but do expect good quality sound for a very reasonable price. These are not earbuds and don't go right into the ear canal but that seems to the secret behind the full sound they produce. The only drawback is that those around you can hear a little of what you're listening to. With earbuds, they can't! Buy these if you don't want to spend a lot - they're good.
