A4C offers the LG Force Bluetooth Headset in Black/Grey for $49.95. Coupon code "SUMMER50" cuts that to $24.97. With free shipping, that's tied with last week's mention as the lowest price we've seen. (It's the best deal now by $10.) They're IPxx5-rated water- and sweat-resistant and feature Bluetooth 4.1, in-line microphone and controls, rotating wrap-around silicone earpieces, an adjustable strap, and rechargeable battery with up to 6.5 hours of run-time per charge (400 hours on standby). They come with two sets of extra ear gels and a carrying pouch.
