Introduction

Audiophiles on a budget rejoice: the Superlux HD668B is a surprisingly good option for those with a discerning ear and a thin wallet. Breezing through our tests, our biggest concern was the connection on the headphones for the removable cable. All things considered, there are few entry-level pickups better than this.

Comfort, Design & Features

Comfortable, albeit ugly headphones.

Due to a high surface area contact with your noggin, and the paddles in the band, the Superlux HD668Bs are fairly comfortable, though you aren't likely to forget that you're wearing them. In the short term, these are comfortable headphones. Over time, not much changes about the fit, but if you have a larger head you're likely to get a little bit uncomfortable with heat buildup around your pinna, so we dinged the score a tiny bit.

We'll cut to the chase here: these cans are pretty ugly.

We'll cut to the chase here: these cans are pretty ugly. Made of plastic and bendable material, they have pretty bad stitching and definitely aren't taking home any tiaras from a beauty pageant any time soon. If they weren't so big, you might think that they came from a child's meal at a fast food restaurant. That's okay though, because if you're buying them, chances are you're more interested in the audio quality anyways.

Usually we rave about removable/replaceable cables, but this system defeats the it's own purpose. Bucking the trend of using a hard-mounted female 1/8th inch jack, the Superlux HD668B uses a male cable termination, which lends itself to breakage much more quickly, especially when you consider that it places the weak point back inside the headphones themselves. Would it have been so difficult to make a female jack? It probably would have cost less to manufacture. Be careful with these.

Audio Quality

Shockingly good for the price

As far as sub-$100 headphones go, the audio quality of the Superlux HD668Bs is absolutely fantastic. They have a flat response without many deviations, which is prized in any set of headphones. These are great for equalizing if you have the hardware or software necessary to do so.

As far as sub-$100 headphones go, the audio quality of the Superlux HD668Bs is absolutely fantastic.

Additionally, there aren't too many blemishes in how the headphones handle sound reproduction. There's very little distortion, only a few very minor errors in channel preference. Overall, these are able to reproduce sound extremely well—much better than their price would suggest.

Conclusion

Great audio quality, but low durability, aesthetic value.

Usually you don't expect this level of performance with sub-$100 headphones, but the Superlux HD668Bs are superstars in this category: their frequency response and performance points across the board are typical of much higher-priced headphones. To have this much performance in a very affordable package is rare.

That being said, there are some things that stand out that should give you pause. For example, the way Superlux granted its HD668B the ability to have removable cables is certainly a head-scratcher, as a male connection on a wire is much more susceptible to breakage than the more common female connection in the housing. Additionally, they include a clip to hold the cable and the connection together, but that just puts even more pressure on the weakest point of the headphones in the event of a tug.

Oh well. If you're looking for a bargain on a set of good headphones, take a look at the HD668Bs— you should be pleasantly surprised at the audio quality, and the pricetag isn't anything to sneeze at either. You may want to see about picking up a cheap amp if you do use these with a mobile device, but it's not absolutely necessary. These are high-value headphones.
