    It paired up quickly with my PX210's, delivered quickly, good sound. The purpose of posting a review was to bring up something I didn't really think about critically or see much of in the reviews, and I admit I was probably a bit nieve and wishful-thinking, but the main problem: this thing sucks all life from your iPod (or similar device)!!! I bought a brand new iPod classic, headphones and this so everything was new. I have a 3hr commute every day, and find myself having to charge up my iPod at least every other day, and sometimes in between. That equates to approx 6 hours play time with this device before my ipod gets to a point of needing a recharge. For the iPod, it has a quoted 36 hours that Apple gives us (which in my experience - I could go an entire week between charges on my old ipod with the same quoted battery life). To go from 36 hours to 6 hours is quite disheartening. I am running some songs on higher than normal bit rate, which would bring down the battery life a bit, but not this drastically. I wanted to be free from cables, but now I'm almost chained to my ipod doc or power outlet. I have run a test and can get a good 5 or 6 meters away before I start to lose signal. great, yes, but possibly this is the cause for it sucking so much power? It would have been good to have an adjustment on the device to choose the range you want to emit the signal - as its always in my shoulder bag, much beyond a meter is overkill. Maybe this is irrelevant and I'm talking nonsense from not actually knowing, but maybe not.
    My only other thing regards the design - it protrudes out a good inch from the base of the iPod. I wish they would have made it wider but shorter, i.e. so that it covered the width of the base of the iPod as opposed to sticking out as far.

    This adaptor is just poor. Constantly breaks it's feed from just a little touch; it's like you have to be delicate during use, or endure constant interruptions of sound cutting off. The bulky fat size design is had is hideous. I have seen far sleaker ones that sit the base along an iPod as opposed to having this huge square thing plugged into your device, this making it more vulnerable and flimsy; it just looks hideous. Two stars was me being generous, because for its

    Sennheiser BTD 300I Bluetooth Wireless Transmitter for iPod/iPhone
    Having spewnt the cost of an IPOD Touch 3rd Gen and PXC310 BT headphones I was very dissappointed to find that there was no direct compatibility between the two.

    This transmitter gives the headphone controls full remote control functions Stop, Play, FF FWD, Next Song, FF RWD Prev Song and Talk through function which means the IPOD can stay in your pocket when in use.
    Sound quality is good but I could not detect any improvement over the standard IPOD bluetooth.

    The extra functionality this gives makes it worth paying ... quid for the dongle, as I'd already purchased the headphones and an IPOD, it just unfortunate that I had to shell out extra dough just to make my headphones work as they should've done in the first place.
    The PXC 310 BT Headphones do not transmit to the IPOD for speech and this is still the case with this BT dongle (No Speech control). I entered this in because I was misguided by review comments to the contrary when buying the headphones.

    Bought both this and BTD300 audio dongle for connecting to my new Senneiser PXC310BT headphones. Relatively expensive accessory but it works brilliantly with crystal clear sound and no discernable lag when watching movies on my iPOD. Hope more equipment now adopt the APTx codec and have it built in as standard. One subtle point that I discovered is that my iPOD will connect perfectly well with the BTD300 audio dongle but without being able to control through the headphones (as per 300i) apart from sound levels. So if money is tight, you could just buy the audio dongle which will allow connection to phone, iPOD, PC, televison etc.

    I got the iPhone 4 and Sennheiser MM400. The link and hence sound would break up, until I got this dongle. Problem solved.
