I was super excited when I received it. It allowed us to do justice to the book. The AKG 170 does the job and is perfect for home demos—for me anyway. Makes the shoes seem cheap and not worth the $100 price tag. Four stars due to some missing frequencies and less than high volume. I love it and I hope you will too. Pros:-- connect easily after first pairing-- snug fit with the interchangeable tips (helps block out ambient noise)-- sound is good-- like that the buttons on the buds can skip forward & backward while listening to music-- good battery life. Sound quality is great and microphone works well. The only thing that could hold these things in is friction, and the tips just dont do it for me no matter the size. I also like that it comes with different size tips, to ensure the perfect comfortable fit for everyone.
