Amazon offers the Motorola S10-HD Stereo Bluetooth Headphones, model no. 89468N, for $44.99 with free shipping. That's the lowest total price we could find by $5, although we saw them for $21 less in August. These wireless headphones feature compatibility with most Bluetooth devices, up to 9 hours of talk time, up to 8 hours of music playback, and hydrophobic acoustic mesh protection for speakers.
