Good, but some things are missing

Good sound quality for the what headphones were designed for. Remember, this is not audiophiles equipment...

Contrary to a few others that i had the construction feels solid and hopefully will survive for a couple of years.

The headphones are very well balanced which makes it easier on the neck. Nevertheless, it feels a bit heavy after a few hours.

Microphone feedback into the headphones was a good idea, so you wont feel as "talking with ears clogged".

Now for a few deficiencies - there is no mute button - this is something you will need to add as an inline switch if you need the functionality.

There is no splitter for traditional speakers and headphone, understandably this might not be a requirement although would be really convenient. Logitech system i have had before was detected as a secondary sound card, hence I could define which application plays through which device.

SoundFX, however acts like a smart speaker rather then a separate system when it comes to computer interface; once again - if you need the functionality you will need to get it somewhere else (splitter with a mute button from RadioShack comes in mind)

Finally, the microphone is affixed to the left side which is where the wire is coming out of as well, there is no way to switch it as right / left are well defined.
