I have to say, that even though I've visited Head-Fi.org before, I didn't plan on actually registering anytime soon... But after seeing this thread and trying out this mod I just HAD TO.
Let me start at the beginning. I'm primarily a gamer. I have an Asus Xonar D2X on my gaming rig and was using it with a pair Creative HN-700 Noise Cancelling headphones (I got both for a song at a clearance sale). But after reading rave reviews about the PC350's great sound quality when it came to positional audio in games, I just had to order me a pair. I also ended up selling the HN-700's.
I was stoked when I finally got them and I loved the look. I hooked them up to my rig and immediately gave them a test run. Although positional audio with Dolby Headphones was near perfect, I was very, VERY disappointed with the lack of bass. This became all too apparent when I put on some songs. My favorite genre being metal, the lack of bass was a real deal-breaker for me. I mean, I had read that the headset was lacking in bass well before I purchased it but I assumed that with a good card like the Xonar, it wouldn't really be a problem. Painfully, not so. I played around with the EQ settings but to no avail. The fact that the HN-700 had been a bass-heavy headset only made the it's absence more apparent.
A friend of mine actually came over to listen to some music and on listening to a track I played him on the PC350's, his very first comment was (even thought he knew nothing about this headset) - "Why is there a complete lack of bass?". True story.
Finally, by happenstance I came upon this gem of a thread. Although I'm not a hardware-oriented modder by any stretch of imagination, the tutorial looked simple enough... so I figured I'd give it a shot. Not having any power tools at home and not wanting to play around with fire (literally) and use hot nails, I decided to use the thumb-tack method. Worked perfectly! With a little pressure and a few twists, I managed to easily puncture 3 small holes in each can. I tried the headset out and noticed a definite improvement... but it wasn't enough. So I took it apart again and this time used two small screw drivers to manually enlarge the holes till I managed to get them to a good ~2mm in diameter. I put it back together, routed the headset through my sub-woofer's headphone out and... HOLY ****! THE BASSS!! It's ALiiiiVE! It's as if I was listening to a completely different headset!
I've never used audiophile-grade headphones before so I can't really compare but the sound quality just completely blew me away! Everything about the headset was now finally PERFECT. Everything. The highs, the mid-tones and now the bass... so sexy, that when amped the headset literally thumps and BOOMS
I've rediscovered music. I'm now going back to listen to all my albums again because I'm now hearing things I'd never noticed before! This disappointment of a headset has now turned into one of the best investments I've made in a LONG time!
Thank you Hero! I registered on this site (as you'll see from my post-count) JUST to thank you! You are da MAN!
P.S. I'm from Sri Lanka
God Bless You. Peace.
