Superlux HD-681 Evo BK

I bought these headphones mainly for just listening to podcasts, audiobooks and so on. They are quite comfortable to wear, although just a bit too big for lying down. The sound is also ok, but a bit too bassy for me. Of course these are matters of taste, but the main problem I have with them is as follows: The two reasons I bought these headphones were the price and detachable cable. Here's the thing, the jack you plug the cable in dangles from a small bit of wire, so it completely defeated the purpose for the detachable. The headphones broke after about 6 months of use. After that I bought Fun Generation HP-7 headphones and although even cheaper they have served the purpose described above for almost two years.

I purchased these to replace a failing set of Sony mdr-cd480.

I use them for listening to music during work hours, so they are on my head for the most part of an 8 hour day. As such, comfort is very important to me.

Unfortunately, they are not as comfortable as my old Sony's.
- The ear cups are not very spacious, and rub my relatively large ears. The felt earpads do fit better.
- The head band has no elasticity or stretch, making it dig into my head, which over long hours becomes quite uncomfortable.

Sound wise, compared to the Sony's they are in a different class. Amazing clarity and detail, and a load of bass.
The drawbacks to the sound were:
- Too much bass, i.e. on bassy tunes I would sometimes have to take them off due to discomfort.
- Too much detail, basically makes listening to poor quality music sound terrible, i.e. they emphasize crackling and hissing.
- Relatively low volume.

On other issues:
- They make a nasty clicking noise when you take them off, as if they are about to break
- There's not much external sound let in, but enough to hear your name called.
- Unfortunately mine failed after a few months (bad contact in left ear).

Overall they do sound really great, but nothing more.

I've been using Superlux cans for a few years now and it's very hard to fault the sound they deliver, although not as flat as you might want for production work they do offer a great reference point for the low end and very high frequencies.

The HD-681 Evo BK do offer the great sound that I've enjoyed from Superlux over the years but the build quality is shockingly poor at best. I returned my pair quite quickly so I can't talk as to the longevity but the plastics are extremely cheap feeling and overall construction is not good at all. I know these are very cheap headphones but still, I expected a little more from this brand.

I found the fit didn't work for me at all, maybe I have a smaller than average head, I don't know but they felt slack and this hindered the compression with my ears and thus limiting bass response and mostly comfort, also worth mentioning this has a big impact if you wear glasses and not a positive impact to say the least.

The positives are purely in the sound, full low end, maybe a little too full for some, punchy mid range although not quite as driven as I'd like and smooth treble, all told you will have a great listening experience here if you are OK with the build and comfort factor these provide.
