Pros: Great overall sound, HUGE bang for the buck, nice looking IEM, works well with most set ups
Cons: can be difficult to get an proper insertion (isolation)
For the price somewhere between $150.00 and $180.00 USD, there really isn't many other competition for the price. They really get the job done well. Can get a little stale in sound sometimes but that's really a rare case. These really are great!
