forbigger Posted October 29, 2009 Report Posted October 29, 2009 Guys, just notice today that my HF-2 emits a buzzing sound when the notes hit a mid note. Like when the piano note hits, the driver buzz. Anyone experience this before ? Is there a way to fix this or should send to Grado for repair ? I hate sending it cause I live in the other part of the world.....but if push comes to shove...... Thanks
n_maher Posted October 29, 2009 Report Posted October 29, 2009 Check and make sure that there aren't any hair's touching the driver or any other sort of debris.
forbigger Posted October 29, 2009 Author Report Posted October 29, 2009 No visible debris or hair......but use can compressed air and clean it......looks like its gone..... Apology Nate for storming and make a new thread.....I really freaked out and its like 3 am. Didn't realize the buzz till i listen to single piano song and no other background instrument...... Thanks once again
screaming oranges Posted October 29, 2009 Report Posted October 29, 2009 wait wait wait... you used a can of pressurized air to blow directly at something as fragile as a driver?
forbigger Posted October 29, 2009 Author Report Posted October 29, 2009 I panicked.......so as soon as I saw Nate's post and the can was at the desk in front of me.....the rest is history. I use it with a reasonable distance from the grille, approx 15cm ? After all, I guess I'm lucky the driver not screwed......

Got the same problem on my PS1, the difference was that the hair wasn't onto the driver, but it was my own hair -the side whiskers-. Had to learn to set the hair before putting on the phones
forbigger Posted October 29, 2009 Author Report Posted October 29, 2009 Feels better that someone has been through the same experience like me......Now I dont feel too bad about myself though I still feel bad about barging in and post the thread. One thing I want to mention is that the peoples in this forum really knows what they're saying/doing.......
Dusty Chalk Posted October 29, 2009 Report Posted October 29, 2009 Next time don't use compressed air.
swt61 Posted October 29, 2009 Report Posted October 29, 2009 I prefer the delicate pressure of a newborns fart. Trouble is you may be holding the phones for some time in waiting. Then again there's always refried beans.
Hopstretch Posted October 29, 2009 Report Posted October 29, 2009 Trouble is you may be holding the phones for some time in waiting. You haven't been around many newborns, have you? They toot as reliably as Dizzy Gillespie.
cetoole Posted October 30, 2009 Report Posted October 30, 2009 Other problem is you are apt to get significant unwanted driver damping that way.
Azazel Posted October 31, 2009 Report Posted October 31, 2009 Well, I for one DO have a problem with my HF2s. Since 'day one', the right driver sounded... er... not right to me. Ok, it sounded right, but in certain moments (bass content) with certain volume level (high) there was one 'clicking' noise, to me this sounds like the driver vibrating and touching onto something. After many (many) burn-in hours, this is still here. And no matter the amp (M3, Beta22, hp out of player, etc) but, as stated, only in some passages with hard bass notes. In normal use (my listening level is quite low, I want to keep my hearing) this is not a problem and I am quite happy with them (believe it or not, my first Grado's!). I compared mine with a friend's HF2 (fresher but burn-in too) and clearly I have a problem (no noise on theirs). Todd suggest shipping them back to Grado as they are under warranty (obvious) but the cost of shipping both ways (plus eventual customs) does not exactly atract me. I looked inside the grilles and saw, on the right side, the cable entering and touching the driver: I have still to try to bend the cable far from the driver with some wire (no disassembly), but when we looked at my friend's HF2 by the grilles the cables looked much worser bent/glued (!)... I recall having read on some forum about this same problem (clicking noise with bass on Grado's) on the past, but am unable to find any info. Any advice? Thanks! Josep
Torpedo Posted October 31, 2009 Report Posted October 31, 2009 Maybe you just can push the wire a bit into the cup, so there's more wire inside, then hopefully it won't touch the driver. It will work as long as the solder joint is upside, away from the wire entrance into the cup. My HF2 seem to be glued inside, so I can't push more wire inside -not that it's needed-, but on the PS1, which don't have glue holding the wire, I need to do that from time to time, otherwise I get something very similar to what you're describing.
Azazel Posted October 31, 2009 Report Posted October 31, 2009 :D:D:D Thanks Antonio! I suspected something like that, and your message pushed me to 'play' with a steel wire on my HF2 cables. Mine are not glued btw, they have just a blob of glue to avoid the cable to be pulled out, but you can feed it inside if so inclined. I will email Todd suggesting this solution if any other customer has this problem... much easy/quick/cheap than sending them to Grado NY Regards from a, now, 100% satisfied HF2 owner
Torpedo Posted October 31, 2009 Report Posted October 31, 2009 Glad you solved it Maybe my HF-2 start developing that problem too. I'll need to look at them better, probably mine aren't glued either.
