I was very excited to learn about this project of headphones made from plastic bottles. They sound awesome, the design is very nice and the project is amazing! Congratulations

The quality of the headphones is excellent the truth was surprised by the strength of the material and how comfortable they are, something to highlight is the Velcro that bring so you do not twist them to keep them excellent product.

The quality of the headphones is good, the functions it brings are great sound modes, cancellation types are very good, the e occupied for work in terms of video calls and audio quality is excellent connects easily between devices something that had me worried because in the specification does not mention it, I have them connected to 3 devices and anchoring one to another is fast, the issue of water resistance is good, I touched moderate rain got wet and as if nothing, In outdoor (street) at the time of making calls you have problems for whoever is on the other side of the call to hear you clearly the microphone that brings not enough to capture 100% your voice you have to raise your voice a lot to be appreciated clearly on the other side, but in enclosed spaces the voice is clearly captured at the time of the call, The battery is something to recognize as it has a long life and it is not that you are worrying that it will run out soon, the low battery indicator is triggered in a timely manner, the total charge is almost 3 hours without doubt an excellent purchase, I would love to make hard case for headphones.
As I have always said, you have to read the manual to get the most out of the product and to know how to switch from one function to another.

I have been using the headphones for two weeks now, the battery is barely 60% used. I use them mainly for the gym, I hope the ear cushions withstand the humidity well, I always dry them after use. The noise cancellation has served me very well and the sound is very good, I am quite satisfied with the purchase so far.

They arrived charged and the battery life is incredible. I use them every day for about 6 hours with noise cancellation active and the battery is still at almost 100%. They are also very comfortable, they do not tire or hurt. I have been using them for almost a week and they are perfect. The cancellation helps me a lot and when you put them in transparency mode they let you hear the voices perfectly and keep unnecessary sounds away. I have also tested its game mode and it does not suffer latency, it is heard perfectly. I also tested the microphone for normal calls and for gaming and with whom I have spoken, they say that the external noise is barely heard and are very clear. Aesthetically they are beautiful. For my taste, it lacks bass, but it is the best investment I've made so far.

The design and color are beautiful. They are easy to connect, the cancellation mode is very good.
I bought them on the recommendation of a video on IG highlighting the materials they are made of. The price shocked me, so I decided to buy them because I had already looked for one months ago but I was not convinced by the price (more than 2,000 Mexican pesos) and that the headband was very loose; as I wanted to use them for exercise, they did not suit me. Anyway, I loved them, they do not loosen when exercising and I think the sound is excellent.
Thank you for making products with less environmental impact.

I loved all the information about the work product and the reduction of the environmental impact and they are very good.

They replaced my Sony WH-1000XM4s headphones. It's amazing the value for money they give you. A little gem.

I liked the design, I was really surprised.

The truth, I believed blindly and they did not let me down, they are super worth it.

They look flimsy but are of good quality and sturdy. The sound is very good and the noise cancellation has nothing to ask from others.
Highly recommended.

Its design is very nice, its battery lasts long, very good grip; you can exercise without fear of dropping them.
Excellent volume and its different audio modes are amazing.
The best investment I could make, I have no regrets.

It is a great product, it has very good sound and the presentation is compact so you can take it anywhere 🤍 I was really surprised.

One of the best purchases I have ever made, loads very fast and is very nice.

It is a product that fits anywhere, it is too light and has a USB C which makes it easy to connect any cable which by the way, comes included, it is green and feels soft to the touch, I highly recommend it. I use it to charge my iPhone XS and it works perfect.
