Hello, thank you for your review. The priority of these headphones is just the perfect ergonomics, to keep the headphones firmly in place and at the same time to be comfortable for everyone thanks to the silicone hooks. But it's probably individual, every person has a different ear shape, something fits everyone differently. Most customers are satisfied with the calling experience of these headphones, among other things. This is probably a defective piece, they should work correctly for in-room calls. Email the manufacturer at
