Perfect for connecting your iPod to your home music system + product details, November 23, 2007

If you’re looking for info on how well this works with headsets, I’m sorry to say that I don’t own a BT headset (yet). This review focuses on the transmitter in conjunction with a Sony BT receiver that I use to connect my iPod to my home receiver, since that was the primary reason that I got one of these. But hopefully you’ll still find something useful.

First off, Amazon’s two sentence product description is a bit too brief, so here are some specs from the packaging:

Communication System:
- Bluetooth Specification version 2.0 + EDR
Output:
- Bluetooth Specification Power Class 2
Maximum communication range:
- Line of Sight approx 10m (30 ft)
Freqency band:

- iPod nano 1st generation
- iPod nano 2nd generation (aluminum)
- iPod mini 1st generation
- iPod 4th generation
- iPod 4th generation (color display)
- iPod 5th generation (video)

Although the compatibility list does not mention it, this add-on definitely works with the iPod classic, because that’s what I’m using. The terminal is the current standard 30-pin connector, so if your iPod is more recent than the above list, chances are that it will probably work… but I can only speak for the classic.

CONTENTS:
The package comes with:
- iPod Bluetooth transmitter
- manual
One funny note regarding the packaging: I couldn’t believe how HUGE the packaging was for such a small item!! The main photo on the package depicts an iPod with the transmitter cleverly placed in view right below the iPod photo, where it would plug in. It certainly catches the eye.

USAGE:
It couldn’t be simpler You just turn on your iPod and connect the transmitter to the port, and in order to activate it, you set your receiving device into pairing mode and then hold down the button on the transmitter for about 7 seconds until the two devices are paired. That’s it.

SOUND:
Overall, I find the sound quality on the receiving side to be excellent. I base my opinion on headphone comparisons between:
a) plugging directly into the iPod and
b) plugging into my Bluetooth receiver unit
As far as I can tell, the sound is pretty much identical, although a bit lower in volume, but that may due to my Bluetooth receiver.

For reference, I’m using the transmitter in conjunction with the Sony HWS-BTA2W Bluetooth wireless audio transmitter/receiver as my Bluetooth receiver. Both these two devices support Bluetooth 2.0 and A2DP (Advanced Audio Distribution Profile). For audio comparisons, I used a pair of Sony MDR-V700DJ Monitor Series Headphones.

One important thing to note is that you cannot control the volume of the transmitted sound. I’m not exactly sure why that is, but it appears to be by design. All your iPod controls behave as they normally do and you can even move the volume slider up or down, however it has no effect on the transmitted sound. Some functions, however, do still affect the sound, such as “Sound Check”, “Volume Limit”, and all the “EQ” settings. Since these features still work, I’m assuming that the lack of volume control is by design. The volume output is the max allowed by the Volume Limit setting.

My only guess is that the volume control is to be used in conjunction with AVRCP (Audio/Video Remote Control Profile), but I don’t have such a device to confirm. I don’t know if this happens on other iPod bluetooth adaptors, but I could see the inability to control the volume via the iPod becoming an issue if you want to use it with a BT headset (unless the headset has volume controls)

RANGE:
The packaging states “Line of Sight approx 10m (30 ft)”. I had thought that Bluetooth did not require line of sight, but Sony clearly states so and for the most part, it holds true for this unit. I have tested up to around 25 feet with clear line of sight and the sound remaind crisp and clear. Clothing also did not present any problems. I buried the iPod and transmitter under a pile of ski clothing with no effect.

But once you block the path with walls or other sources of interference, the signal will start to become choppy or completely cut off. Be warned that your body can also block the…
