  Thanks!
 
I turned off the water at the main and then opened all my faucets and left them open. Luckily my pipes didn't freeze and the house was under 0'C (32'F) for about 5 days straight. I brought my Bose QC20i's with me to my dad's place (he only lost power for 4 hours) and I gotta say I am very impressed with them. They sound pretty good (best Bose headphones I've heard yet) and their noise cancelling circuitry is simply astounding! I thought the QC15s did a good job, but these are on another level.

Are you in the GTA? My parents are downtown and it seemed like they were the only ones with power. I escaped to PEI for Christmas so I missed it all

Yep...in Toronto by the lake. We got NAILED! Funny I lived in Ottawa in 1997-1998 and thought that ice storm was something. Imagine my luck to get twice with two of the worst ice storms in Ontario's history.

MH, do you use EQ? Many Head-Fi'ers don't for some reason, leading to somewhat biased reviews.

I typically do not either. That can introduce distortions, but from time to time I have used it sparingly.

Sometimes, turning it down won't create distortions, but turning up will... for some headphones, not all

I was thinking the same thing. I will occasionally increase a band a smidge but generally try to tame frequencies that are spiked vs increasing the other bands. But bilsonchang007 only have success part of the time.

Yep, you're right xD 
 
On the side note, I am seriously bad at EQ-ing because I basically turn up the mids for almost every headphones I used to EQ before. Mids is just way too fun to EQ up IMO xD

 

[Trunks159]

I basically always EQ to flat (unless they only have a reasonable amount of warmth like the MA900), and lessen the EQ if I hear distortions.  My Impressions on a certain headphone have changed like day and night before.

well said!!

Apart from that I wonder what different people mean by “mids”. Big difference if we talk about the 500Hz to 1kHz area or if we talk about the 2k to 3k area.

A propos: The other day I saw a fellow talk about 5k as “mids”.
Musically speaking (at least) 5k is far into the treble. The highest tone one can squeeze out of a violin -the main treble instrument of the orchestra- is about 3k. Also the working span of most treble units is typically from 2k and upwards, and they are very often used with crossover freq of between 2k and 3k. (They produce treble, if you wondered). Has the 5k guy ever heard an isolated 5k tone, one may asks.
Some misunderstanding may come from the FR charts, who knows. The tonally insignificant octave between 10 k and 20k takes up much space on paper. But those frequences are not “treble”, rather mostly “air” (of course).

P.S:
Main thing, the rightly placed upper and lower bumps gives excitement.

There are frequencies charts that do not seem to agree entirely on what is an exact range of the middle frequencies, the studio audio engineers and the musicians seem to have different ideas about that. For us on head-fi dealing with headphones I would suggest as the fundamental untouchable area of the middle frequencies to be the full range of the men's and women's voices, the range of 50 Hz to 1000 Hz. I mean untouchable to the headphones frequencies response + deciBel tuning that results in headphones having the recessed mids. Any headphones that significantly lower the volume of the sound with the vocals, in any part of 50 Hz to 1000 Hz range, are to be designated as defective headphones not fit for the humans. Very good headphones [like T1 or W3000ANV] have full volume presentation extended to 2000 Hz, that means no big drops of volume up to 2000 Hz. 50 to 2000 Hz covers all the fundamental tones of the men's and the women's voices plus all of the first harmonic series overtones, [plus the second series of harmonic overtones of the frequencies 16 to 670 Hz and the third series from 16 Hz to 500 Hz - the more series of harmonic overtones the better, the tonality of instruments and voices is more full and pleasant ]. http://en.wikipedia.org/wiki/Harmonic . Broadly speaking for the world of headphones the middle frequencies region has an upper useful limit of 3500 Hz. At around this frequency, depending on an individual and his or her ears, the human ear tends to be very sensitive to the shrill resonances. The good headphone manufacturers try to lower the headphones volume output in the frequencies around 3500 Hz.
Useful charts, I include the one referenced previously by another member of head-fi. All in one place.

Hey, MacedonianHero, are you getting the NAD Viso HP50?

 

[zorin]

  ~~I'm new to the forum (first post) but I have read the other entire 58 page thread covering the UE 9000's , and during the course of that purchased a pair of them from JB Hi-fi in Auckland NZ. Retailing at $599 NZ which is about 480 US. I paid 483 NZD which is about $380 US. So, not cheap headphones. Prior to purchase I compared them in the store with Bose QC 15's and of course was impressed with the ANC of those. I also listened to some B+W P3's and some Sony Momentums. All similar prices maybe dearer. All listening was done wired. . I've been using a pair of Technic RPDJ1210's (yes headphones not turntables) I've always considered these amazing cans, as in really amazing. Does anyone on this forum know them? So so clear, like electrostatics. Sure not for bassheads but well I am not one of those. So the other cans I tried at the shop were all good possibly better but they didn't have Bluetooth. That's what I wanted, so I bought these. I'm struggling to accept that they are good enough and while I appreciate the comfort and the freedom Yeh FREEDOM , did you hear me say freedom, wow that is so cool - the truth is the sound is muddy in the bass and recessed all the way up. Especially if I compare them to the Technics. Even compared to my Kef speakers (Reference Two's) which aren't generally considered particularly lively they (the Logitech cans) are veritably muted in the mid and upper ranges. So I've had them a few days and I have been adjusting to the sound on BT but its galling to think they could be better if I sacrificed FREEDOM. I had noticed a buzz when I was leaning on a pillow, that I could make appear or disappear by leaning back. weird. Today I started gaming with them - (Need for Speed on the Ipad) and something that I had noticed before became much more apparent. I describe this as some sort of electronic glitch. like a loose wire making a slight crackling noise. I had noticed it in between tracks when listening to music , and also when listening to the radio. It happens when there is a change in the type of sound being broadcasted and is particularly noticeable when the game intro's and you make your selections (of track, car etc) Its only on Bluetooth and I believe it to be the ANC componentry kind of clicking into place. I've also noticed occasional blackouts of sound for a second or two. So I think I am going to have to take them back as faulty. I am kind of sad, but for this amount of bucks want the BT to work easily. I know it can , I quite often drive the Kefs via a Bluetooth device in front of the Denon amp using the IPhone and it works perfectly. (Although there cutouts in IOS 6 - this has been fixed in IOS7) Does anyone have any comment about the Technics RPDJ1210s. Am I right they are good? Am I right

Ahhhh xD those pictures of FR xD they really helped me a lot till today. xD

 

[Trunks159]

The ES FC300 looks interesting. Tyll sure loves them. Guess Ill go buy them to see what the hype's about! .............. bought at $150!

Ditto, well done!
