The sound was alright, but they were a hassle to use. They do feel comfortable but I regret getting them because of how they look. what it does mean is that using the volume + and - on my iPhone is far less useful because the increment is too much. Bought these for my 87 year old father. But it is used every day inside so it?s perfect for home use. Real Swede will snap under pressure but this stayed together after putting a lot of pull on it. The rubber on the bottom of the slippers as good grip. First, im impressed with the value of this IEMs. 5", my typical size, but they were just slightly too small, so I upped to 11" because, other than the length, the shoes had fit like a dream. There was a model available that Sennheiser used to sell for $20 at one time that had considerably better sound, though, which was my introduction to near-audiophile quality headphones.
