I'm giving some thought to the MM550's as well, and I'd love to hear some people chime in, while I can't argue the convenience and the lack of wires...

How does sound quality compare vs a wired headphone with portable headphone amps?

How do these compare to wired versions? I'm interested in the 550's because of the bluetooth functionality, but if I'm losing a lot of sound quality over a wired headphone and a headphone amp, then what's the point? Especially at that price point?

Now if it's comparable to a HD650 with say a headroom stack then are the days of lugging wires and amps along with an Ipad/Ipod gone?

double post, sorry.

Hopefully Skype's developers will be hammered into including bluetooth support on future versions.


That's about it! Will post extra feedback once I've done some airplane testing.


Cheers!

 

Don't know about Skype, but Garageband will never support Bluetooth - the latency is too much to allow real-time playback of instruments.

I have a pair of Sennheiser PX 210 BTs (which are simply awesome for the money), and just to test, I've paired them up with my Macbook Pro and tried playing software instruments in Logic Pro - same problem - you hit a key, and the note sounds a good 50-100ms later.  Doesn't sound like much, but the latency of a good digital soundcard for music production is around 5-10 ms, any larger delay than that and it really affects your playing...

Most headphones don't work with iPhones. However, if you already have an iphone Bluetooth Headphones and is not willing to buy a new one then here is your alternative solution. You can buy adapters which will help you play music or make and receive calls
