The sound quality is very good for their value for money, while the volume they have is much louder than all the handsfree I had until now. They seem durable so far, although I would like a slightly better plastic quality.

Unfortunately, after 4 months of careful use, the microphone doesn't work and I can only use them for music.

After 15 days, one earphone doesn't work.
They have proven to be completely unreliable.

Quite good, powerful and full sound with bass boost from the mobile.
The function buttons fortunately worked as they should - android - (that's what made me buy them in the first place) and the cable was indeed difficult to tangle.
Problems with the microphone compared to other handsfree sets I have tried, many times they struggled to hear me.
Unfortunately, not durable. The "connection" between the cable and the earpiece often came loose and the internal wires would come out, which likely caused one of the earpieces and the buttons to stop functioning after about 1 and a half months of use.
In the end, I consider them a bad choice as they are one of the headphones that lasted the least for me.

The headphones are indeed very good for the money they cost (€10 on 4/4/17). They fit perfectly in the ear, isolate the sound at very satisfactory levels, and have a long cable. Their bass is moderate for my standards, but it is quite powerful at a level that you might not be able to withstand at maximum volume for a long time. Their buttons work perfectly (volume adjustment, play-pause, next-previous by pressing play-pause twice for the next track and three times for the previous track).

As for the negatives: They don't hear me clearly during conversations (at least on the phone, I haven't used them for Skype, Teamspeak, Facebook calls). The area where the three buttons are located, the "plate," is like made of cardboard, but it doesn't affect the button functions. On one hand, it makes them very lightweight, but on the other hand, they might not withstand the test of time.

I highly recommend them. I don't think anyone can find better hands-free headphones for €10, at least in the Greek market. I should note that their price is €9.90, so it's worth buying them from Greek stores on Skroutz that price them at €10.

Positives: Very powerful, very good balanced bass, with decent isolation, flat cable, compatibility switch button for android and iphone. Comfortable, with a soft cushion.
Negatives: In some low-quality songs, the mids may slightly escape.

For their price, whatever I say is not enough.
