It's been quite a while since I've come across some products from JayBird, and this time around we're talking about the field of wireless headphones. These are the SB2 Sportsband Bluetooth Headphones, and are here to keep users free of tangled wires, especially for the likes of you that like to jog.

As far as the company tells puts it, the SB2 is completely capable of ensuring CD-like quality, without the need for a wired connection, thanks to their apt-X audio technology. The technical specifications are one of the most important factors when choosing a pair of headphones, so let's check those out.

I will start with the 32 Ohm impedance, which in this case is irrelevant, because the headphones sport their own amplifier. Sporting a level limiter, present because of the EU regulations, the SB2 Sportsband has an output power of 15mW, and a maximum sound pressure level of 117dB with a variable 3dB attenuation-amplifications over the frequency range.

Speaking of the frequency range, it's important to point out that these things have a frequency response range of 20 to 20,000Hz, which is realistic, considering the product category. With a weight of 106grams, packed with Bluetooth 2.0 + EDR technology, the SB2 headphones can be used as far as 10 meters from the transmitter and cost $99.
