Superlux HD-669

I have roughly around 14 sets of headphones & these are in my top 3
i use them daily (along side the dt 770 & hd25) for editing, mixing & daily listening.

-Pros

+Build Quality is super solid
the removable mini-jack-type connection is a freaking lifesaver, it has saved me & musicians from breaking the cable like +10 times

+Fit
the support wings have metal arms so you can bend them to fit abnormally large or small head sizes

+sound quality is superb
its insane for this price, it easily beats other cans 6x its price. i measure (frequency analyse) all my headphones & there are super small differences in the Left Right hi end (+7K) response which adds depth to the stereo spectrum.
overall response has flat mids, 10db sub boost (20-90hz) & 7dB hi end (5K-12K) boost (with a typical 3.5k cut)

+price
you shouldnt be able to break em, but if you do, its not even a big deal

Cons

-Comfort
the original ear cushions are a good quality but they are a to firm for me so i ll be upgrading them with Brainwavez hm5

Like I said in other review of the Superlux HD-660's - I bought these Superlux HD-669's to replace a pair of much loved Sennheiser HD-25's that finally died after ten years of heavy use. The Superlux HD-669's were recommended on a few websites (headfi.org was one of them I think) that said these headphones were basically unsung heroes and were punching well above their weight.

I took the chance and bought these, not expecting them to match the €300ish pair of Sennheiser's but figuring they could come in useful anyway. They are more than useful - I love them. The low end is enveloping and the mids/highs are as detailed and clear as I could want.

Like the HD-660's their downside is their size and poor noise isolation, but to me these are non-issues really. As a testament to them, I recommended them to an engineer friend (who now heads a sound department on a major US tv show and he could not believe the sound. He then asked a producer friend, with some big projects to his name, to mix something with them, without showing them what they were and he who loved them - and that was before he knew the price.

So in short - don't look elsewhere if size and isolation aren't a concern. Quality all round.

I've bought them for mixing and mastering in my little studio. The headphones gives a really clear and natural soundThe phones have a straight EQ curve. The bass is so huge but personally bit too much of treble. But it?s just a matter of personal point of view and preferences. Well from the bad things I need to mention that they?re quite big and looks ugly on my head. Moreover there are not the type of headphones which can be used for many hours in studio because they make me headache. But despite all these things I still do recommend these, because if you want good headphones for cheap this is good choice. You just can?t beat that for this price.

I love these earphones! They deliver a very high quality sound with good balance all round. Excellent for recording and listening back to your pieces of music with clarity and depth. I have rated them five stars all round except for comfort as they can get uncomfortable when using for longer periods of time which is reasonable. They are cheaply priced and i'm very surprised with the quality of this product giving their low price. The detachable connection jacks which offer a short and long reach is a very nice addition and quite useful for certain situations. I have been using them for over a year and they are still performing extremely well with no problems. Highly recommended.

I bought these because I wanted a pair of closed headphones for use when recording. I have been very pleased with them, not only with the noise isolation (for which they were purchased, but also because the sound quality is very good for such a cheap set of headphones. The frequency response is pretty flat, and the tonal reproduction is excellent.
There is a good length of cable so that you don't have to stand next to your audio interface or mixing desk if you are recording in the same room as your equipment.
I now tend to prefer these to my pair of Sennheiser open cup studio headphones when working with headphones. As mentioned earlier, they cut out a lot of background noise and allow you to concentrate on the music an mix (if that is what you are using them for) and they are comfortable to wear for long periods.
I've been very impressed with Superlux and will definitely be considering their mics in future.
