Noise Cancellation
I have wanted a noise cancellation headphone for some time but never did pick one up. I have tried my cousin’s Bose QC 2 a few years ago. While the QC 2 does it job, I did not like the sound/pressure it builds up. Since then, I have read reviews of the products in this space (Bose, Sennheiser, Audio Technica, etc) as well as the technology behind it before I took this plunge. Does the BH-905 live up to Nokia’s claim of achieving up to 99% of the external noise reduction?
Simply flip the ANC switch on the side of the headphone to activate Active Noise Cancellation (the green/red LED right beneath the ANC switch indicates the status). Well, noise cancellation does work, filtering external noise so one does not have to adjust the sound volume. I tried this on my commute to work (noisy train), machine room with noisy air conditioners. I feel that it is able to cancel out constant rumbling from the surroundings, but not people – which is good. However, when the headphone is not playing music, I can still hear some rumblings. Overall, I am quite satisfied.
Voice capturing
When I was on the train, I made a couple of calls with ANC set. Unfortunately, the receiver could not hear very clearly what I was saying. It turns out, the headphone’s two microphones for voice picked up all of the noises from the train while I was able to hear very clearly what the receiver was saying.
In conclusion, the BH-905 fulfills most of what I want. It is not a headphone for audiophiles but will serve well in a noisy environment where one does not need to speak.
