Main effective range 80 to 1000 Hz? I'm not sure!
OK it's not expensive, but I still expected a better result. I bought a total of 4 CBT1s and 2 CBT2s, and there's almost no difference. Especially below 500 kHz, they are very ineffective. I could probably just use a pillow instead, and it would do the same job
