I bought these as a backup for my Shure SE535 units. I was pleasantly surprised to find how good they are. These are the standard earphones that Sennheiser ship with their wireless systems and they do the job very nicely. There is an element of noise cancelling without the really snug fit. They are comfortable to wear and can be worn over the ears. They are neither overly bassy nor overly bright and would be suitable for vocalists and instrumentalists. A good flat response, even good definition for kick drum and bass. Recommended as a starting point for your choice of in-ears and unbeatable performance for the price! recommended!
