  • This review is about the colour: Black

    Awesome!! I had bought them before and back then they cost €50 and now half that, but they are worth it. The one with the microphone doesn't work on many headphones, especially wireless ones, but they are convenient!!

  • This review is about the colour: Black

    Very good sound and convenient setup for their price. Convenient that they fold for transport. The battery is large enough so you don't have to think about it much. The microphone doesn't work very well, it sounds like it's coming from a well. With the phone in hand, very good connectivity, however, it often loses connection outside the house. They always act up when I pass under power lines or trolley wires. Also, as other users have pointed out, it has a short range, resulting in disconnection if you turn your head the other way or carry the phone in your left pocket. There is also an annoying rhythmic noise from the left earphone. Imperceptible during normal listening but very annoying during low volume playback or silent intervals in movies. You can definitely find better products at this price now.

    I have had them since 2019 and they still work, only the cushions have worn out. They have good sound for their price with good bass. The Bluetooth gets interference if you move away.

    I have had them for over a year. The positives are that they have lasted until now, the sound is loud and clear, and the bass is fine.
    The negatives are that the microphone practically never worked and the Bluetooth, when in an environment with few interferences, gives up.
    It is impossible to walk a long distance and listen to music, it will immediately cut off, freeze, and stop.
    If a taxi passes by you 7 times out of 10, it will interrupt. If the phone is in the opposite pocket from the receiver of the headphones, 9 times out of 10, you will not be able to listen to your music without interruptions. If you turn your head, even slightly, it will immediately pause. Overall, the Bluetooth has issues.

    This review is about the colour: Black

    They constantly have sound interruptions, it's annoying from the day I bought them, I don't know. Maybe it's the Bluetooth or something else? I do not recommend them. I bought them because they were wireless but they are very bad. They are not worth even 25 euros that I paid for them. I have wired ones with a 15 euro offer from Genesis Gaming that I have been using for 3 years and they have perfect sound and bass. I don't know if I got a defective one.

    This review is about the colour: White

    It is definitely value for money. I have had them for 2 years and they work perfectly. They are comfortable, have good sound, and their bass is very powerful. Their construction is not so sturdy (plastic), which is why they are also lightweight, but personally, it did not create any problems for me, with a little care, they will not break. The cable is durable and connects directly to the mobile, as well as the direct connection via Bluetooth. The only negatives I can point out are its average battery life and its microphone, which is characterized as average to poor. However, let's not forget that we are talking about headphones worth 20-25 euros. I would definitely buy them again.

    This review is about the colour: Black

    They would be good headphones for their price, if they didn't break so easily a piece that cannot be fixed and you need glue.
    No, I didn't misuse them and I took care of them. And then they tell me that they don't have spare parts in the company and they can't fix them for me.
