wonderful model, really honored

IMHO, these are simply ideal headphones for their price. Raju for bass lovers. The wire is strong and reliable. I guess it will last a long time. I immediately thought that the sound guide was just included in the kit for fun, but it would actually change the sound. These are my other headphones from the Knowledge Zenith company, as well as accessories from them.
Clear sound, excellent quality of materials, good equipment.
Did not find anything for myself.
