These headphones sound way more expensive than you'd think. Out of the box, the value for money is amazing. They even come with spare velour pads as an option.
Build is plastic and comfort is pretty good. I found them better with the velour pads which are quite soft although some might find the clamp a little tight. One member of my site found the velour a little itchy. I can wear them for a long time though.
Sound as sold is good, although there is a pretty potent bass and a strident treble. Some folks may well like this sound. I found the bass deep, but detatched from the mids and the treble a little strident.
However, with some really simple alterations, they become outstanding. All that is needed is electrical tape and tissue paper. If you remove the pads, there are 6 vents on the baffle plate. Tape over 4 of them. Place 1 or 2 layers of tissue over the front and put the velour pads back.
The result is a stunning listen. Bass is slightly lowered but goes amazingly deep. It integrates better with the mids and the treble is tamed. In this form, it's a five star sound whereas in stock form, I'd say a four star sound.
These mods take literally minutes and you end up with a stunning buy. I'd say the best of the Superlux line up once modded.
For full details and measurements, you can visit my headphone site where they have been tested with results of the mods to compare, by Solderdude. DIY Audio Heaven will supply the details.
