Reviews “Scope of delivery and design are top-notch while comfort and usability of fit and handling leave nothing to be desired. The in-ears are convincing in terms of sound with fine trebles which convey a good stage sound as well as a rich sub-bass… The bottom line is that the buyer gets an enormous amount of “value for money” because it’s a well-developed product with a very solid sound at a very fair price.” — headphonecheck.
