Amazon has discounted the Plantronics BackBeat PRO 2 Special Edition Wireless Headphones today, bringing the price down to $159. These typically run for around $249, so that's good for $90 off of the regular price, which is definitely worth taking advantage of.
The Plantronics BackBeat PRO 2 do offer some pretty good audio quality, as you'd expect from a pair of headphones from Plantronics. These offer immersive and high-resolution sound, with some pretty large speakers. So that's going to give you some pretty bass-heavy lows, as well as crisp highs and natural mids here. These do also offer up Active Noise Cancellation or ANC. This means that you can really zone out to your music and not worry about what is going on around you. That's definitely a good thing here, especially with the amount of battery life you're getting here. Plantronics touts that you'll get around 24 hours of continuous playback on the BackBeat PRO 2. Now you can also use these with the included cable, and make them wired headphones – also useful for when you are flying and want to use the seat-back entertainment. Finally, Plantronics does also offer up a great travel case for the BackBeat PRO 2 Special Edition here, which is going to keep these safe when you are traveling. These are a great pair of headphones, and at $159, they won't be around for long, so you'll want to grab them before they are gone.
