I just bought them for use with my creative x-fi3.
The secret of good - nearly audiophile sound - with bluetooth devices lies in the used bluetooth codec.
Standard BT- codec is SBC with often quite low bitrates.
But there is another BT-Audio-Codec, called apt-x, which providess much better and even lossless transmission of audio-files.
There are only few sources providing the apt-x-Standard.
According to this site these are the following:
- Motorola Razr
- Samsung Galaxy Tab 7.0 Plus
- Samsung Galaxy Tab 7.7
- Mac OS X
- Creative ZiiO Tablet
- Creative Zen X-fi3
- Dongles from Sennheiser, Creative, Jaybird
The newer Sennheiser BT-Headphones (MM100, mm450....) do all support apt-x.
The senn MM100 paired with the x-fi3, playing lossless files using apt-x, sounds in fact very good, even better than my beloved px100 (old model). No recessed mids and highs, bass is more punchy and tighter.
But there are some issues, too. The mm100 sometimes "freezes". You can still hear the music and change loudness but you can't skip or stop songs anymore. I don't care that much 'cause I mainly use this rig in the gym or for running or biking. Just throw all your favorite songs on the player and there is no need to skip ;)
