N97 Audio Equalizer Settings

Hi bronxboy, i am sure you are a true audiophile and will appreciate good sound reproduction. i salute that. after all every artiste will want to have their music reproduced they way it was recorded 

just one thinny...... you modify headphones too..... hahahha coolness!!!!

for me at the moment on the go i am using the SONY DR-BT140Q Bluetooth earphones. i kinda like the wireless thinngy though.

i chose these because their effective freq range of 100Hz to 4kHz but still capable of the full audio frequency spectrum. i figured that because most of today's compressors be they MP3 or WMV, there is a drop off of high frequencies from 10kHz and above.

also looking at the way the N97 reproduces music, this could be a good choice. personally, i dont experience the high frequency nuance and thanks to the EQ, i can isolate the Bass at 53Hz. also, because of the 100Hz effective range, it takes care of the low frequency rumble.

give it a shot my friend. if you can get a demo pair, try them with my EQ setting above.

let me know ya.

cheers!!!

Wooo.... looks very futuristic 

strange though... they never listed down the audio specs of the headset.

hmmm...... let me see if i can find some to put it up..

no worries my friend.... thank you for sharing 

pls find the English version of the page http://europe.nokia.com/find-products/accessories/all-accessories/headsets/bluetooth-headsets/nokia-bluetooth-stereo-headset-bh-505

Hi disturbed... not too much faith in Nokia now ehh... hahahahahaha

Audio Freq: 10Hz to 20kHz, this all looks impressive however, being the ear bud type design, i am quite doubtful it can hit 10Hz. for its size to hit 20kHz is not a prob, provided it is well designed. Must test to find out.... because i doubt i may buy it, i guess the only way is to go down to the Nokia showroom, pair it with my phone and see how it goes.

THD: 500Hz to 8kHz (ah ha...!!!  here is where the whole story unfolds....)
by stating that the THD is at this freq range, it shows that this pair of earphones has an effective range of only such.

i guess in the R&D + manufacturing process, Nokia also figured that most MP3 files are compressed with a drop off after 13kHz so by limiting the response of the earphones to 8kHz with our phone's EQ isolation at 11.8kHz will sure produce some good highs; but may be only just. we still have not considered the frequency separation factors yet.

as for the lows, this pair will for sure cancel out the low freq rumble as it is effective from 500Hz and above. with our phone's EQ isolation, it will be good to produce hopefully as low as 100Hz.... i am just guessing because of the range of EQ from 59Hz to 259Hz as based on the N97. In this case, we may be able to hear the bassline but might not necessarily feel it.

I am not sure exactly what the attached DSP may do but it could help enhance the effective frequencies to produce an image of bigger and fatter mids. this is to make up for any nuances missing from the highs and depth of the lows. something like the artificial LOUDNESS thinngy....

just IMHO... however, thru the number of years i played with these, it should be quite an accurate picture la.... hopefully if someone here gets it we may kindly request for a review.

perhaps when it arrives in singapore, i may speak with my friends at Nokia Care to see if i can get a test drive 

Cheers!!!

10HZ is pushing it & even if it does hit it something like this could do serious damage to your eardrums. most don't realize it but the reason people talk so loud as they get older is because they can't hear even themselves.

 Take care of your eardrums. Distortion is their worst enemy.

Yes, please test the Nokia bh-505, im also intressted in them, and give us your thoughts on tthose when the time comes

Do you think something like this would have good base and great overall sound reproduction?

i was just looking at this for a while.....

again, IMHO only, i think this has something to do with the design and construction of the earpiece. from the diagram, the low freq and low-mid freq module is in front while the high is behind.

shouldnt be that the high freq module be in the front? reason being the high frequencies having shorter wavelength, less energy, will hence travel shorter distances before distortion occurs.

by having the low and low-mid freq modules at the back, it will not only reinforce the high freq driver in the front however, it may also act as a vibrating block, similar to a sub-woofer system, when the earphone is inserted into our ear. the surrounding ear cartilage will hold it snugly in place. you may then experience the so called sub-frequency rumble in the head thinngy....

just a second thought guys.... any comments???

cheers!!!
