Plantronics Backbeat GO Bluetooth Stereo Headset (Bulk)Product Review (submitted on October 22, 2012):
Like them so far, but did not get the eartips or stabilizer piece with the bulk model here. spend the extra $10 and get the regular boxed version if this is important.
Like others have said - they don't get super loud. But otherwise seem ok sound quality. Can't comment on fit until i get the tips that fit. Bass is a bit anemic with the small ear tips it comes with. Hope to compare once i get the right tips and see if it becomes a bit fuller w/ more low end.
Customer service has been fantastic so far. Unfortunate i had to call them and they need to update the description to say this is just the headphones and charger - no other accessories included!
