Ars digs into the nitty gritty details on using a Bluetooth stereo headphone …
If pairing a stereo headset, a window with the known services of the new headset may appear. The Plantronics stereo headsets will display both the headset and headphone options. Click Continue, and then Finish. You will be returned to the Bluetooth devices window. On the computer, you can influence the amount of compression the SBC codec applies by modifying the editable Bluetooth compression variables listed here:. Don't forget the quotation marks in the variable names.

However, when I cranked up the bitpool settings too far, the headset wouldn't produce any audio anymore. I was impressed with the solid reception and distance the Bluetooth audio works over. It easily goes through one wall, and when Bluetooth has to compete with WiFi both use the 2.
The only circumstances under which the audio would break up and even then usually not that much is when my iPhone would get caught between me and some solid object, or when I would walk across an open field in front of my house. With my iPhone in my left pocket and the MM's electronics on the right side, apparently there need to be some objects in the vicinity for the Bluetooth signal to bounce off of to circumnavigate my body. The solid reception lasted until I had been using the MM for about a month.
One morning, the audio kept dropping out—badly. This kept up when I left the house, so apparently it wasn't the neighbors transferring big files over WiFi or nuking some popcorn in a badly shielded microwave. Nothing I could think of would clear up the problem. Fortunately, the MM, like most Bluetooth headphones, comes with an optional cable for use in airplanes.

The next day things were back to normal. This keeps happening about one day a month. The fact that it's impossible to debug the problem is unbelievably frustrating. Other things I have learned: first, the volume on the headset and that on the computer are independent and work in multiplicative fashion.

So, you can use either to turn down the volume, but you only get the maximum volume by turning up both. What I do is keep my iPhone volume set to maximum—fortunately it remembers the volume separately for each output—and use the MM buttons to select a pleasant playback volume. On the Mac, I set the Mac's volume to around two-thirds, which makes the volume with and without the cable the same.
How to easily connect Bluetooth headphones to your Mac computer
Connected to the Mac, after an hour, the headset turns itself off to save power. Not so with the iPhone, which keeps the headset awake until it runs out of power. Voice Control is a bit slower than normal because the Bluetooth connection first has to be switched to HSP mode so the microphone can be used. The headset insists on reconnecting to the last connected device when it's turned on; making it connect to another device requires a few extra steps—it's not quite as simple as unplugging a cable from your iPhone and plugging it into your computer.
On the Mac, there is a very noticeable audio lag. This is very obvious when changing the volume using the volume keys on the keyboard: the feedback clicks are noticeably delayed. Forget about playing back video; the synchronization between the audio and video is off by a lot.
This is strange, as the SBC codec is supposed to be optimized for low latency. Maybe the fact that lips are so much smaller on the iPhone screen also helps. Finally, a few words on the Sennheiser MM Although I was impressed by the Bluetooth audio quality, the MM is bested in audio quality by much cheaper headphones. The electronics create a little noise in the right ear and turning up the volume too much makes the headset resonate. I was disappointed at first by the noise canceling feature: it didn't seem to cancel that much noise. After using the MM for two months walking to work past a busy road, I did the same using regular headphones and I really noticed the difference.
Although you still hear pretty much everything with the MM's noise canceling active, you can easily listen to audio without cranking the volume up much, if at all. With the regular headphones, I need to set the volume to painful levels to follow what's being said in a podcast I'm listening to. The noise canceling does take the edge off with traffic or plane noise, but it doesn't do much for voices.
I was surprised to see that keeping Bluetooth on the iPhone 4 didn't impact battery life perceptibly, at least not compared to the battery life when trying to blast 3G through the steel and concrete cave that is my office.
Using the headset wirelessly also doesn't seem to have a huge impact, although I've rarely done that for more than three hours a day. The big question is whether it's worth all the trouble. Having to charge another battery pretty much every day, being surprised by "bad wireless" days, the poor audio quality in HSP mode, the video-killing lag, and the extra cost all scream "No! Still, getting rid of that wire is really nice.
