Works GREAT!
1 of 1 found this helpful I took it from the package when it arrived and started using it with a cheap, generic rtl.sdr and a 7 band 132 ft OCF dipole. I was trying to hear if any difference between the generic rtl.sdr HF mode and the Up converter HF mode. I was sitting on the edge of a hard bench and by the time I got up, I was thoroughly HAPPY with the excellent sensitivity of the upconverter and my leg was asleep because I couldn't tear myself away!

Poor quality control
You'd think they'd check and make sure every key works before shipping. One didn't. You get what you pay for.

My first noise cancelling headphones are a success!
We live in hot Texas and always have air conditioners and fans going all the time. I like to listen to music in the evening in bed. When I switch them on, the outside "whirring" goes down to nearly perfectly silent and music seems to increase in volume so, I turn it down! I can see why they'd be effective on a jet plane's steady state noise. Pleasantly surprised! Inexpensive, and effective is why I gave them 5 stars.
