    Headphone EQ

    Here in the first 10 pages are where I post my EQ graphs. The actual settings are under hifi-misc. Note that the horizontal lines are 6 db apart above and below. http://dalethorn.com/Photos.html

    Headphone EQ

    I'd agree with the minor changes to nudge a small midrange coloration to less colored, or to fix a small but irritating anomaly in the bass or treble that "just isn't quite right", but it's pretty close. That's the best situation, because bigger changes always affect adjacent frequencies, and even when you have a great parametric equalizer, getting the bandwidth perfect to prevent narrow glitches in the adjacent frequencies is beastly difficult.
  3. Here's my comprehensive review of the new Grado GH3 in the Heritage Series. It's neutral, it's spacious, it's made for music, and nearly as light as a feather: http://www.hifiheadphones.co.uk/community/threads/grado-gh3-heritage-series-stereo-headphone-review.4535/
  4. The great Steve Guttenberg has opined on the GW100, saying that it's OK but not quite like a real Grado (quote approximate). The user comments are interesting, and I answered a few: https://www.youtube.com/watch?v=8QdQpQ9N1-s
  5. Well, I tooted my horn enough - here's a guy with a 20-minute review -- 20 minutes is a stretch, but his presentation is pretty good and informative.
  6. A new question about the GW100's replacement earpads came up on a large headphone forum, and I thought the answer given was for the wrong earpads, so since these earpads are easy to lose when they fall off unexpectedly, I thought it would be good to post the correct replacements here and elsewhere. Replacing any headphone's stock earpads with a different design is likely to make a major change in the sound, and the change is more likely to be negative than otherwise. https://www.bhphotovideo.com/c/product/1434308-REG/grado_w_cush_replacement_foam_ear.html/?c3api=3679%2Cbing%2C81638766845622%2C4585238367528178&msclkid=790f7bcdba9d16cccb6a200730f9f6df
  7. I had the 1770 pro, but ran short of funds to get the 1990 pro. I'd like to read your impressions.
  8. I added a new video to address additional questions:
  9. I came across this interesting review on the 'MajorHiFi' site, and thought it would be worth highlighting here, because of the unique design of the GW100 as an open-back wireless headphone. Here are a few excerpts and a link: "As an open-back wireless headphone, this model has almost no competitors." "Compared to models from Audio Technica, Sony, Sennheiser, Marshall, Bowers and Wilkins, and Bose, nothing at this price point can even compete with the GW100 in terms of sheer sound quality." "For those seeking isolation, choose any of the above and enjoy what you can. For the rest of ya, this Grado is everything you could want in a headphone." http://majorhifi.com/grado-gw100-review/
  10. Tonight, 7-1/2 days after receiving the GW100, the factory battery charge finally ran out. While I did quite a bit of listening in wired mode at home (and the sound is excellent), I'd guess my Bluetooth use amounted to far more than the rated 15 hours during these 7-1/2 days. The first few days were pretty intense doing various tests, with lots of outdoor listening in areas with moderate to low noise levels. As best I remember, the low-power voice warnings started about 45 minutes before the "power off" notice occurred, as the headphone shut off -- out of power. The good news is there was no distortion or interruption (other than the voice warnings at ~5 min. intervals) to compromise the sound as the power wound down.
  11. I finally configured my best-guess EQ curve for the GW-100, based as usual on reducing peaks and recesses, toward achieving a real-world natural sound. This is a better result than what I got with the SR325e, and much better than my GH1 (although the wood for the GH1 naturally varies from sample to sample). The actual settings are in the HiFi Misc./EqAppReview document. Although I haven't been able to determine the comparative fidelity vis-a-vis the other Grados (I don't have those on hand), I was able to get a pretty good handle on the deep bass quality after boosting 35 hz by 3 db. Playing the Kellogg Auditorium 16 hz sample organ pedal track, I was surprised at the amount of fundamental (including 32.7 hz doubling I'd guess) as well as the detail of the 16 hz 'beats'. http://dalethorn.com/Photos/Audioforge/Grado_Gw100.jpg
  12. Firstly, I'd recommend strongly to consult with a doctor or doctor-equivalent audiologist before using any compensation other than a mild frequency adjustment. My hearing isn't as acute as it was 20 years ago, but fortunately it's still acceptable for hi-fi listening. As long as my headphone sounds the same more-or-less as natural sounds and music that I hear, I'm OK with that since that means the headphone is accurate. When it gets to the point that I feel a real loss of sound, I'll probably look into a hearing device that also works with large headphones.
  13. The KRK I had was pretty neutral. The Superlux's are not. AKG's vary a lot - the K553 is excellent, but the very cheap ones aren't.

    Headphone EQ

    If you listen to a headphone and it sounds obviously colored, especially compared to a headphone you have heard that sounds much better, there's a chance you could apply EQ and have a good result. Parametric equalizers are best since they allow you to set the exact frequency and restrict the width of the change, so your change doesn't spill over into adjacent frequencies. In my experience, I'd do two things -- boost any major recesses and reduce any major peaks, then listen for midrange colorations and try to address those. If there are several such problems, the chance of success is pretty low. Applying EQ in the music player before the signal hits the DAC is best, but any changes you make could overload the amplification, so you might need to decrease the player's output and increase the volume further down the line, to prevent distortion.
  15. I finally got one - it's on youtube. Well worth the wait - excellent Grado sound.
