Pretty good sound and noise reduction especially for the price. Fairly comfortable on my treadmill for the 30 to 45 minutes I am on it. I am well satisfied.
The BT300 ANC is worth considering if you are looking for wireless, noise cancelling headphones that perform like Bose or Beats. I have used these on several flights and it blocks out quite a bit of noise on the plane. Took one start off because the headphones stopped functioning (no power on/off) after 11 months. Still, for about 1/10th the cost of their competition, it's well worth the price.
1 month purchase. Definitely an upgrade from my non noise cancelling headphones. But It doesn't compare to the Bose or other high end phone. I was mainly looking at noise cancelling ability to create a isolated work area and I still can hear a lot of external noise. That being said, for the price the product quality is very good and I think it will last, as long as I take care of it.
