I got these to replace my old speaker headphones that didnt have great audio. i wanted inner ear plug style to try them out. my bluetooth set was liek that. I have to say i was pleasently surprised at the differnece in teh audio from my old set. i listen alot of audiobooks so its alot of talking. The audio difference in Voices i had to question the characters for a second sicne they sounded so Human as if i was there vs just sound comming form a speaker in my ear. Im so happy at how clear and crisp things are and when i switch to some dance music the bass really set up and was confortable to wear. Minimal Vibrations and felt great. im very pleased with these. Also side note they came in a great wood looking box that had a storage bag in the bottom you can place your headphones in when not in use. thought that was a nice added bonus.
