"These headphones were a great upgrade and starter set."
Pros
Great sound, many pieces to allow the best fit possible. Very good noise cancellation.
Cons
Internal wiring problems lead to non function of left earpiece. Housing on right earpiece slowly came apart, it still works great but holding it together with tape.
Summary
Great all around earphones, quality may be a bit of an issue. Very pleased with the sound quality and fit, disappointed they were unable to hold together for more than a couple of years.
