5.0 out of 5 stars The Best In Ear Headphones with Mic for cell phone phone calls.

I've tried many brands of in ear headphones but none can compare to the sound quality with deep bass that the Betron MK23 has. A pair of headphones of this quality could easily surpass $100. However, what a bargain at only $9.99 here at Amazon.com, I am very satisfied with these in ear heaphones from Betron.I've tried many brands of in ear headphones but none can compare to the sound quality with deep bass that the Betron MK23 has.
