A recent report from IMS Research is forcasting clear skies for Bluetooth technology this year, claiming 500 million Bluetooth-capable devices will be shipped this year. Stereo bluetooth is still in its infant stages, but making progress. A2DP compatibility on phones has been a considerable bottleneck for market penetration, but so has style. The Motorokr S9 is a good example of how stereo Bluetooth design is becoming more mainstream, and after swinging by a Telus store last night, I found the even-sweeter BTS-500 (just came out last week, not on their site yet). BlackBerrys have been toting Bluetooth for a hell of a long time, but emerging markets with high demand for low-cost, low-feature handsets could potentially stunt Bluetooth growth. If you’re in the market for some Bluetooth headsets, take a look over here.
