Conclusion
The HD661 are an excellent addition to Superlux's already impressive budget line up. The HD668b will suit those who want a more flat sound with a tad more bass response while the HD661 will cater wonderfully to those who favor treble, but still want a clear balanced sound with good bass response. The build quality is great for the price, though I wish Superlux would consider a leather band or another option in place of it's wing system. The Samson SR850 are much more comfortable than the HD668b, for example, because of that and are still able to be found for the same price. Either way Superlux seems to have found it's niche, making excellent products at a budget minded price. I highly recommend the Superlux HD661 for it's suggested retail price of $50 for it's versatility though I have to say I highly enjoyed alternative rock the most through these.
For those looking to purchase these, unfortunately they are a bit hard to find. If you e-mail Superlux though I'm sure they will assist you in finding a shop or a place online!
