BlueParrot S450 XT or B450 XT which is better?

I have a B450 XT headset now but it’s starting to have some issues after having it for a year now so I was wondering if I should try another one or get the S 450 XT.
With the S450 I’m not sure how I would like the double ear thing and I don’t plan on using it for music.
I was just trying to find out about the performance and what people think about it that have one.

 

Get both the double ear piece is great for AFTER work. Listening to music or watching TV. It SUCKS while driving, or for phone conversations. If I could only afford one, I'd go with the b450.
If you like your blue parrot, dont even consider a blue tiger. It works fine, but the difference in how the ear piece fits your head will drive you crazy. Plus adjusting the volume while on a call. Will disconnect you.
