After debating what to go for I took eozen81's advice and bought the SE MW600 for just under £36 from Amazon. So just some quick feedback after 2 days use:
Reasons for buying:
1) Mainly to use in the office, as I don't like leaving my phone on my desk, I found it a chore constantly disconnecting my earphones before pocketing my phone.
2) While at my desk, didn't like to keep pressing the power button to wake phone to pause music.
Pairing:
- Unlike me to read the instructions, but after some digging around some users experienced dodgy sound quality and connection dropping, I tried to get the unit to pair automatically with the DHD but it didn't play ball. So I manually scanned and selected the headset from DHD.
- So far no problems!

- An added bonus I think is that you can pair upto 3 devices to the headset.
Sounds Quality:
- Didn't even bother with the set of earphones that came with the headset.

Cuttenly using my 2yr old set of Sennheiser CX300 II.
- So far it's been fantastic, no drops, calls are clear, music coming through as if using wired headphones.
- Not tried the FM radio (I hardly listen to it), but will try over weekend and add to my feedback here.
Controls:
- Its probably my fat fingers, the call and power button I found a bit fiddly to press, but slowly getting used to it.
- Back, Play/Pause, Forward buttons work with PowerAMP absolutely fine.
- Volume control - still getting used to having to slide it one way or the other to inc/dec volume, would've preferred buttons.
Battery Life:
- Only done a single full 8hrs charge so far, will report later.
Comments:
- For me the bluetooth headset will not replace my need for a wired set of headphones with inline control for when I'm out and about to conserve battery, but I need a bit more time to shop around for an ideal set.
- I highly recommend the MW600 @ £36. If you are considering this and want a better set of earphones, keep in mind to look for a set with a 3.5mm I-plug. I have a set of Denon C452 coming to keep me going till I can get a more decent set.
