I was skeptical about wireless headphones until I tried these pair. I love this pair of wireless headphones because the sound quality is amazing. They have clear sound, the bass is super and they fit nicely in my ear. The set up was very simple when it came to connecting them to my phone. After reading the instruction manual, it was very easy to understand exactly how to turn up the volume or just simply answering a phone call. You can use just one headphone if you'd like and it's pretty convenient. While on a phone call. I was easily heard and understood as long as it wasn't too much background noise. The charing case is so great! I like how you have to open the case as well. You can charge the case and use that to charge your headphones without plugging it in. Overall, best purchase for Bluetooth wireless headphones and a great recommendation as well.
