If you don't have Bluetooth enabled in your car, HTC and Sprint have just what you've been looking for: the official HTC Car StereoClip is now for sale from Sprint for a cool $59.99. This tiny accessory is equipped with a 3.5mm headphone jack that will plug into your car's auxiliary port, along with an 85mAh battery that provides 5 hours of streaming playback and 120 hours of standby time. It will pair seamlessly with the HTC EVO 4G LTE or any device in the HTC One Series.
Of course, this accessory will also work with any Bluetooth-capable phone from any carrier, although HTC device owners get the benefit of automatic pairing.
The HTC Car StereoClip supports Bluetooth 2.1 + EDR (minimum), Advanced Audio Distribution Profiles (A2DP), and the CSR aptX codec. It also automatically powers off to conserve battery power, hopefully minimizing how often you'll have to charge it. AT&T is also expected to carry this accessory soon.
