I wouldn?t say these earphones are flat due to this colourisation but all earphones, headphones seem to have their own sound signature either too much bass, or raised mids etc. I suppose, if I really wanted to, I could even listen to music from my phone quietly while listening to meeting audio since the headphones just play both sources together. But as it is, Ive never had headphones that blocked out that much noise, or sounded this good. 5 minutes with a steak knife solved that problem. This is a wonderful shoe if you?re a kayaker or enjoy being out on a boat with shoes on? It does it?s job perfectly! They offer the support that I need!
