But while stereo Bluetooth headsets have their advantage, I’m disappointed by their sound.  Then I realized that what was missing was the audio enhancement what is “SRS WOW”, which is basically a software equalizer on my phone. (SRS labs has licensed the technology to a host of products)

If I listen on my phone with a wire, I can turn on SRS and WOW, it sounds much better! (base enhancement, 3-D sound)

Not so when playing the same tune over my Bluetooth headset.  This sound enhancement doesn’t cross the Bluetooth bridge.

Credit goes to IO Gear for producing the only Bluetooth headset I know of which has licensed SRS WOW, and their Bluetooth Audio Transport presumably can enhance audio from ANY phone.

But despite the allure of stereo Bluetooth:

• The sound quality may be worse than wired headsets
• You must have direct line of sight between your phone and your Bluetooth, otherwise you will experience the infamous “skipping” of your audio content
• You have to keep your Bluetooth charged – hard enough to always be ready with a spare battery for your phone, but to have your BT always ready? (The battery is hard-wired; no swapping possible)
• You may also have to hassle with “profiles” to toggle between audio and phone calls. I had this problem with Windows Mobile 5, but others report it works perfectly....
• Your phone battery will discharge faster if you have Bluetooth pairing turned on
• For all of these “features”, you have to pay for the device!
