Bite-Sized Review Plus Giveaway: Superlux HD661

HD661 Unboxing 5

Contents (maximize to view)

Superlux is known for selling quality yet affordable headphones. The Superlux HD661 is one of the headphones that boasts quality sound output without bursting your wallet. Our friends from XT Corporation gave me a unit and let us see how it fares.


The HD661’s retail box is definitely one of the attractive-looking cardboard boxes I’ve seen. I must admit that it looked a bit pricey, but at PhP1,990, I’m sure that in the supra-aural monitoring headphone category, this one is really a pretty good deal.

What you get inside the box are the following:

  • HD661 Professional Monitoring Headphones
  • 1M Straight Cable (3.5mm jack)
  • 3M Straight Cable (3.5mm jack)
  • 6.3mm adapter (for you, mixers, out there)
  • Documentations
  • Soft carrying pouch

Build Quality

XT Corporation gave us one in neon orange, but the HD661 is available in 11 different colors: black, white, red, neon pink, pink, neon blue, neon orange, neon purple, gray and neon green. The quality of the headphone is definitely outstanding, somewhat unrealistic for an accessory worth less than PhP2,000. The swivel mechanism that holds the ear pads is made of hard plastic but surprisingly sturdy. Build quality alone, I’m confident that this headphone is really a bang for your buck.

The availability of 1M and 3M straight cables is of course perfect if you use your headphone as part of your get up. In my experience, I switch to the 3M straight cable when I’m going to use the headphone on my desktop PC at home where I usually play my games. As this headphone’s output produces good bass, you can imagine how I enjoyed playing Diablo 3 and Guild Wars 2 on my PC. Of course, the 1M cable is enough for me when I want to carry the headphone with me when going to the office. I just thought that it would have been better had Superlux included a coiled cable in the package. I wouldn’t mind paying an extra PhP100 – PhP150 for it.

Sound Quality

With the HD661, what’s definitely more important is the quality of sound it produces. HD661, in this aspect, gives off good sound quality, which commensurates to its inexpensive price.

I must say that Superlux greatly improved the treble that this headphone produces. I can assure you that the treble this headphone produces is acceptable. Songs are listenable and lyrics are definitely understandable. Its little bassy but it does not mean that it’s a bad thing. There is a balanced mix of treble and bass as I mostly listen to pop, jazz and a bit of house and dubstep. If you prefer a “bassier” can, I’d recommend the HD631 more.


I am not actually an audiophile, but from a consumer’s perspective, this one’s definitely worth buying. For PhP1,990, this headphone is definitely worth the price as it also includes a lot of goodies (cables and 6.3mm adapter)! The availability of 11 colors to choose from is of course perfect for fashionistas and hipsters out there. But of course, what’s more important is how this produces the quality of sound consumers look for! The HD661 perfect complements consumer’s preference as it considers and balances sound quality, style and affordability.
