Xiaomi's earphones are 1000 forints
If you know cheaper than that, I'll eat my hat!
Xiaomi’s cheap yet quality stuff ranges from entry level to mid-range, although there are some that are plenty of top-notch, such as their home theater projectors, which I’ve already written about. The structure called the Xiaomi Piston earphones fresh version represents the entry level of the earphones.
It has a traditional membrane tab, which, however, also got some extras. The 3,5mm jack plug earpiece got the same look as the more expensive solutions, but not only the shape but also the housing is similar, as even this cheaper piece is made of metal to reduce resonance and get fuller sounds. In addition to the metal housing, we even get a Kevlar-fiber-reinforced cord to minimize the chance of the cable breaking.
The headset is available in five colors, silver, blue, pink, purple and black, but the black version is now available in HNYear478 with a coupon code you can buy it for $ 3,99, which is about 1000 forints. Shipping costs just 21 cents, so you can even say it's free.
