Performance
I plugged the earphones into one of the new Philips GoGear players, and then to the PC directly, to run some small tests. My verdict of the sound? Well, the high mids, at the frequency range of 7-12K, were bumped and not good, at least in my realm of subjectivity. The reason I’m saying this is I’ve heard some strange opinions on straight up bad-sounding responses before.
Nonetheless, this intensive high-frequency response can most definitely be heard and even liked by some, though the volume should be kept low, or ear fatigue will occur for sure.
The bass is decent; it’s pretty tight too, though it’s not the USP of the product. I actually wanted a little more bass in the music. Vocals and other mid frequencies do get affected by the upward bias in the high mids, and while some of it sounds good, due to a feeling of ‘crispness’, I think its overemphasized. The overall level of this earphone is very loud. It has a decent to good dynamic range, but the depth and ‘3Dness’ is not too good.
The NC circuit first raises the volume by at least 6dB, so it helps to cut noise, and the circuit is not that noisy. There is a bit of noise that's easily audible in relative quiet, though not when music is on. The battery lasted for as long I reviewed it, which was a couple of days, so I suppose that shouldn't be a problem – and besides it works without the NC too.
Conclusion
Rs 1995 is the price, so that makes it one of the cheapest active noise cancellation earphones. It has some good points, besides, so this one goes squarely in the middle. I would recommend it to those who aren't too particular about frequency response, and just want a loud and working NC earphone.
Can I have the price please?
