Firstly I liked the packaging this product was in. After I took it outside the box and interfaced it with my Samsung j6 blue tooth phone the audio opened up really awesome. This headset goes well with Sony Xperia as well. They provided 6 months warranty as well. It worth the money and ergonomically designed to fit well on eyers. Various variants are available, bass expander, hip hop and terrible booster. I have bass expander variant
