### ⭐⭐⭐⭐⭐ Very good headphones for a decent price!
*by A***9 on January 5, 2021*

I really like these headphones, they have great volume control and decent noise cancellation. The sound quality and when I speak it sounds really good.

### ⭐⭐ Don’t order it if you need a mute option
*by M***N on February 5, 2026*

It didn’t have a mute button

### ⭐⭐⭐⭐ Product contains only headset. Pricey but Worth It!
*by P***G on May 6, 2017*

Word of Caution - Please note product contains the only headset. This is QD headset and it does not contain QD to USB cable. So please remember to buy it separately. The Product is really nice. I have used in an office environment and it allowed me to take calls for longer duration without any problem. Although I am based in India, delivery was really awesome. I placed an order on 1st May and I got delivery of product on 5th May itself. Although I paid extra for speedy delivery but overall delivery and packaging experience is good. I placed an order from Rally Bargains Inc.
