Noontec Hammo S

Noontec has released an updated Hammo headphones. As I have reviewed the earlier version, I decided to test the new Hammo S to hear the difference.

The design is identical to the Hammo, even the hard travel case. The Hammo S includes an additional cable. The difference, apparently, is on the sound, as Noontec claims the new Hammo S is the result of a 2-year development and “over ten thousand professional tunings”, as well as changes to the materials to improve durability. To me, the Hammo S is certainly an improvement over the Hammo.


The Hammo S is best enjoyed at moderate audio levels. It delivers good bass presence without too heavy or boomy. The treble is adequately clear without sounding fatigue, while mid-range level is enough to offer some warmth to the listener. Sound staging is tight. The Hammo S is ideal for listeners who favour treble over bass.

But when I turn up the volume hoping to enjoy my music to the max, the bass beats sound hard, the treble is marred by emphasis of mid-treble, unrefined sibilance, and messy high-treble, which can get uncomfortable.

The Hammo S is a pair of fashion headphones, comfortable to wear, with good sound isolation to cut off noise of playing children in the same room while I typed this post. I enjoy the comfortable bass presence, clear treble but can get messy at loud volumes. Foldable headband is great for travels, and the flat cables prevent any annoying tangles.
