These speakers include front cover, they are come from CRESYN factory that made headphones for many famous brands, you need to disassemble the speakers from the front cover yourself to DIY your headphone.

This type speaker sound very good, it is HIFI type speakers, with balance sound, clear voice sound, not much bass sound, if you only like bass sound, we don't recommend you buy this speaker, I think the origin headphone price over USD199.

We also don't know this speakers origin brand,  if you know which brand and which model of this speakers, please let me know, if we confirmed you are right, we will send you a pair for free as gift.
