Creative Pure Wireless Bluetooth Speaker System (T12) | Audio ...

Bought these to use with a new Dell Inspiron 14R, which includes an Intel Centrino Bluetooth module. Using a Logitech V470 Bluetooth mouse with it with no problems. Wanted wireless speakers mainly for convenience.

The Creative speakers work fine but there were a number of issues I had to do the research on and resolve to get it exactly the way I wanted. Main thing was the speakers would NOT auto-connect to the laptop when it booted — I had to manually press the connect button on the speakers. Sounds like a little thing but this was TOTALLY unacceptable to me.

Turns out this was a limitation of the Bluetooth stack on my laptop, NOT the Creative speakers; short version is — the default BT stack installed by Microsoft in Windows 7 for systems with an Intel Centrino BT module is very limited as far as functionality and that means no capability for things like auto-connection for audio devices, etc. So, some hunting around and I located a 3rd party, non-Intel, PREMIUM quality BT stack from Toshiba which solved the problem, costing me around $35.00. Definitely worth it though — once paired, the speakers switch over from the internal laptop speakers to the external wireless Creative BT speakers automatically and seamlessly a few seconds after booting the system.

I did notice that musically, the Creative speakers were WAY too quiet and exhibited a preponderance of bass and lack of high frequencies, a matter that was easily resolved using the equalizer and pre-amp control embedded in iTunes 10.x. Once adjusted, the audio quality is now “pretty good”, especially when seated directly in front of them and with sufficient separation.

ALSO — unlike some of the other reviewers have noted here, I have NOT had any problems with audio drop-outs from using a BT mouse, even during heavy use of the mouse (like in games). Perhaps that is (at least in part) due to the fact I am using a premium Toshiba Bluetooth stack and not the default Microsoft/Intel stack.

At this point, I am 100% satisfied with the purchase and recommend these speakers highly. Works with Linux

Con’s : Other bluetooth devices interfere. I’ve got a Bluetooth mouse and with it connected frequent drops in sound, need to disable mouse and just go with touchpad.

All in all I’m very happy, I dropped one star for this not playing well with other bluetooth devices connected. But I’m still very happy with the speakers I recommend them as a wireless speaker system with quality sound.
