eBay is currently selling the popular Plantronics BackBeat Sense headphones for just $69.99 with free shipping. These typically go for around $120 - and actually still are that price at other retailers like B&H Photo. So this is a great deal to jump on, especially if you've had your eyes on these for a bit.
The Plantronics BackBeat Sense is a very comfortable pair of headphones that you can pick up and use. This is thanks to the memory foam that Plantronics uses on these headphones, so that you can keep these on for hours and hours at a time without them becoming heavy and uncomfortable to wear. Additionally, Plantronics touts that these have up to 18 hours of continuous playback, which is pretty good for a pair of wireless headphones, and is on the higher-end of battery life these days. Plantronics touts that these have rich bass, with some crisp highs and natural mids, for those that are worried about how good the music quality would be on these headphones, it appears to be quite good actually.
eBay does offer up free shipping on the Plantronics BackBeat Sense, and they are selling out quickly, so you'll want to pick up your pair now before they are gone. eBay also does not collect any taxes on this purchase.
