Sound Quality

The CS100 produces clean mids, punchy bass, and decent highs considering its budget price. Directional audio comes through clearly in games.

The closed-back design provides good noise isolation from ambient distractions. The soundstage feels spacious for a headset.

Whether taking calls, enjoying music, or gaming, the CS100 provides quality stereo sound that outperforms basic computer speakers.


The plastic construction feels sturdy enough for daily use. Padding on the headband and ear cups prevents discomfort over long periods.

The boom mic picks up voice clearly while remaining unobtrusive. On-ear controls let you adjust volume and mute on the fly.

Customer review

The headset is very light and comfortable, it might seem fragible but it is made of pretty good material. It will not apply pressure to your ears, and the earbuds are very comfortable, as well as having a slight 30º degree rotation (on its axis).

As far as sound quality goes, it is above average compared to other cheap headsets out there (~20$US seems to be the above average price). The speakers sound pretty decent, as long as you use them for voice. The high notes are pretty notable (accentuated a little bit too much), the midrange is ok, and the bass surprisingly manages to perform very well for the price. It is there and it serves the purpose of voice chat.

As far as the mic goes, it is not a professional mic (those are $30-$200), but it manages to perform well.

The microphone is very omnidirectional, so keep in mind for example I have a somewhat loud computer fan half a meter away from the mic, and you will hear it in the background.

As far as voice range goes, it manages to capture low notes pretty decently, again I have to restate, for the price, it is what you get. If you are not doing a radio show or a podcast, then this is great for voice chatting, gaming, voice recognition, etc.

A good tip would be to adjust the mic to be above the mouth by a few degrees and also turn its inner face way from you. Doing so allows for a better sampling of your voice as the recording will not be crippled by constant air noises from your breathing.

On the technical side, you might want to note that the microphone also has an outer side, so not only it captures your voice, but the ambient noise. The cord is pretty long, just enough to be comfortable, but not long enough for you to roam freely (I have it plugged in the front of my computer).

Final note: Good headset for the price, good for people on a budget.

Recommendation: If you want better quality, pay more, but if you just want to voice chat on Skype, this is great and cheap. Always test audio products before you buy them.
