Summary: I was pleasantly surprised by this headset with open air earphone receivers and dynamic microphone costing between $40 and $45. I usually prefer a closed cup earphone receivers which attenuate ambient noise in the shack from cooling fans and the XYL wondering when I will finish my chores. This headset is very comfortable, with low clamping force. It stays on, but does not pinch or squash my ears against my head, and it sounds good with strong and pleasant audio.
Summary: This is one of the best kept secrets in amateur radio I think. This is a really nice headset with excellent audio both on RX and TX in a lightweight and inexpensive headset. No problems driving a variety of radios over the years. These are compact, on-ear headphones and do not block out external noise much so are not as well suited for a multi op station or really noisy environment, but are great for other uses where you do not need to really attenuate external noise.
Summary: I have received consistently excellent audio quality reports with this headset using a Yaesu FT1000MP, TenTec Omni VII and Elecraft K2 and K3 transceivers. They are lightweight and open-air enough to wear for contesting in a tropical environment. Comparatively cheap and relatively durable, they are my choice for DXpedition and Field Day operation. They come with mini and 1/4" plugs, so they work with many rigs out-of-the-box.
