Model overview based on user reviews  
The Koss SB-40 headphones are praised for their excellent sound quality, comfortable fit, and effective sound insulation, making them suitable for extended use without discomfort. The design is robust, with a reliable build and a long, thick cable that allows flexibility in movement. However, the microphone is a significant drawback, with users reporting issues such as poor sound capture and the need to hold it close manually due to a loose mount. While the headphones excel in audio performance, especially in gaming, the microphone's inadequacy makes them less ideal for communication purposes. Overall, these headphones are recommended for those who prioritize sound quality and comfort over microphone functionality.

A godsend for a radio amateur.

Superb headset - I use it with radio communication equipment. In all respects it makes the famous Heil. It is included in Hale adapters without alterations or modifications. NOT for use with computer sound cards - a dynamic microphone does not provide the proper amplitude of the sound signal at the sound card input; this requires headsets with an electret microphone.
Excellent headband design, good dynamic range of emitters. Excellent amplitude-frequency response of the microphone capsule. The capsule is dynamic, and its parameters are tailored for use in communications equipment - hence the problems with amplification on computer sound cards.
the play in the microphone boom mount is somewhat annoying.
use Koss SB-40 month or more i recommend it should buy
generally ok, but the microphone is bad

buy for people who do not speak on Skype and do not communicate while playing online, in general, those who like to play on a computer.
the headphones are wonderful, the sound insulation is excellent. no extraneous sounds are heard. They don’t put pressure on your head, you can sit all day without difficulty. In addition, a long and thick cable makes it possible to watch movies at a distance and not worry about damage to the cord.
the microphone is terrible. the interlocutor constantly complains that I can’t be heard, i.e. variable. sometimes good, sometimes bad. There's a lot of noise and you can't hear anything.
use Koss SB-40 few months
They could have thought of a better microphone for this price.

Suitable for those who are in pain and do not need a microphone.
Great sound, fit well on the head, comfortable.
The microphone is bad, you almost have to yell into it so that you can be heard normally when recording or talking.
