Knowledge Zenith ATE earphones.
Incredibly good earphones for the price, beats the pants off of the xaomi earphones which are popular.
They look a bit like hearing aids - but trust me they are good, dont sound tinny or that cheap nasty sound. They have decent build quality too and wont explode after a few months.
Anyhow a true Chinese sleeper product - something worth buying at a really good price.
They will however have the compulsory nigh on a month delivery time.
