Superlux HD-681 F

These headphones are an affordable option which deliver good sound and are comfortable to wear. I found the basic response to favour higher frequencies, but with some EQ tweaking a balanced sound is easily attainable. In noisy surroundings these headphones do not provide adequate isolation, so they would be more suited to applications in quiet environments.

The versatility of the screw-on jack adapter makes it easy to use on portable devices or standard 1/4" jack headphone sockets. After about three years of moderate use the connection at the jack started to fail, rendering them unusable until a new jack was soldered on.

I get temporary tinnitus from time to time - ear infections, etc. My ears REALLY didn’t like these - them causing fatigue within minutes. The Superlux, even though marketed as “flat” really fatigue my ears to the point of causing temporary tinnitus. So if you have any sort of over sensitivity to 6-10K, I think you should pass.

My AKG K245’s haven’t ever caused this issue so I’ll be going back to those - it’s been things like listening to mobile phone speakers too closely or anything too trebly that my ears can’t tolerate.

It’s not anyone’s fault, these are just not for my ears.
