strangely well-built for the price, sturdy, good battery and great sound quality for the price, maybe the microphone could improve, but it's okay, good value for money, simple and straightforward.

Very good, excellent sound insulation

Very good indeed, in terms of comparison it is quite similar to the Havit H2002D that I had, just configure its mic because at higher frequencies it pops a bit kkkkkkk (on Windows go to its mic settings and leave it between 90 and 97, or test it to see if it pops or not), its sound is impeccable, I only have a reservation about the size of the earpad because it's quite big and might "sit" on top of your ear, but nothing that hinders its use.

Fast shipping, well packaged, sounds very good but it was difficult for us to synchronize.

Cost-effective phone, highly recommend for the value. If you have any questions, check out my review and test on YouTube, channel Dangz.
