Theory on Noise-Cancelling in-ears : better tuned versions of the original?

post #1 of 3
Thread Starter 

This is just a small theory on my part, but I can't help but wonder about this after having an interesting experience with two similar in-ear sets.

I currently have an Sony EX300 (those vertical in-ears) with 13.5mm drivers sticking outwards lol.
I recently got given some noise-cancelling earphones which are the Sony NC33s. (that's digital noise cancelling)

 

Given how similar they look I thought hmmm chances are they probably use the same drivers and the performance would be pretty similar. Doing a bit of research here most people seem to agree that the cost of NC's in majority comes from the noise-cancelling technology itself and where as the IEM itself would be ok at best and doesn't justify a high price (I live in Australia btw).

 

I decided to take them for a spin and using my Walkman Z to play a range of FLAC, MP3, and m4a files I used the EX300 and the NC33 to play through my favorite songs.

 

While I have used the EX300 for a while, I was able to find some differences between it and the NC33.

 

The NC33 seems to be slightly better than the EX300 in terms of bass texture (NC's seem to be a bit more Solid), Midrange (NC's seems to do a better job at presenting them), resolution (NC's sound more vivid) and the overall sound (NC's are bit more I guess Natural is the word?)

 

What do you guys think?
Its a slight difference of course, but has anyone else ever thought that NC in-ears maybe slightly better tuned than the original unit from which they were derived from?

ANC itself should only cause distortion to the sound in theory , however it is not inconceivable that ANC headphones have different tuning due to the space needed for the ANC circuit.

 

However looking pictures of the EX300 and NC33 I do believe they are different earphones, and given that the ANC circuit is not inside the housing it is unlikely ANC is the cause of the change in sound.

I actually didn't use NC on the NC33 when using them, so sort of like what the NC33 might be like if it wasn't a NC model.
Once I turn the NC on it seems to be more or less like the EX300, particular in bass and midrange, I was thinking maybe the NC33 was to be tuned a bit better in those areas in order to compensate when NC kicks (the weird bzzzz noise)
