Conclusion: For $100, these earphones deliver warm bass, decent high-frequency clarity, and noise cancellation that gets rid of ambient sound—although they do add a bit of hiss.
Pros: Decent noise cancellation. Good sound quality for the price. Nice, deep bass without overwhelming frequency balance. Excellent, firm fit. "Monitor" feature mutes audio and noise cancellation for conversation.
Cons: Active noise cancellation gets rid of most ambient sound but creates a bit of hiss. The included clip is annoying but necessary for bulky noise-cancellation circuitry.
