What they said!
I love my MW-600s, depending on what music player you use it sends track info to the OLED screen on the dongle (Works with stock player, not poweramp
)
You can pair up to 3 devices to it, I have my PC, phone and Laptop paired up.
Sound quality is great but I had some driver issues with Windows but that was resolved.
It's my second pair after my first pair were stolen as soon as the police said
they couldn't do anything I ordered a new pair right away £30 I paid.
They also work great for a home audio set up, plug that into the AUX port on your stereo
and you can control your music from the phone without getting up.
9/10 I give them, they lose a point because the ear buds that came with them have started to get a minute crackle in the right driver.
