I love my CQ Headset. Sooooo quiet. I just bought the bose A30 to compare the newest and greatest in aviation to the CQ. Wow, it’s going back to Amazon. I’m not sure the dB difference but it is significantly higher than the CQ at the highest noise canceling setting.
Prior to my CQ Headset, I had the clarity aloft. There is really no comparison with the CQ. The CQ is much higher quality, with lots of choices of consumables available for really reasonable prices. Thanks guys, for a really freakin great product!
