Review: Denon AH-D1100 - Page 5

post #61 of 70

Aw! man, I just bought these headphones and now I'm reading about the terrible build quality problems with them. They've already shipped the phones so I'm unable to cancel the order. I noticed that no one mention these kind of problems in old reviews, I think it's more of a recent problem. Is Denon using some type of really cheap plastic, maybe? 

 

@Frankrizzo you should try some epoxy and see if that works, I'm really sorry.

Nah, I got them when they were practically just coming off the assembly line.  They have always had this problem.  It is really unfortunate too since other than those damn forks, they are well constructed.

I was really excited about these headphones, I think I won't even open the package to try them...what a shame. In fact, I was thinking on buying the D2000 until I saw the price at amazon, it's insane. Denon should recall these headphones since they are obviously defective. Now I don't know which cans I should get.

They seemed fairly solid when I owned them, I tend to baby my headphones though. The D1100 are good value if you like bass at their street price of around £60.

Yeah I wanted some headphones with a good punchy bass. I bought them for about 69 pounds plus shipping, and I baby my headphones (and pretty much everything) as well. I can't believe Denon is having this poor build quality issues, I thought it was a reliable brand.

Ive had my D1100 for about 5 months now with quite heavy use. The Denon Logo has fainted a bit, but no priblem at all for me in term of build quality. For under £70, I doubt you can find better bassy headphone. Acoustically I prefer them to the M50 or DT770 but less strongly built as it seems.

geez, so sorry it broke.....never SIT on your next pair of cans. :P

i try to baby all my cans....even the rugged pro900. 

 

Added a foto of my little mod on the shell in my previous post.

cant resist giving it a try...i mean its 50mm drivers..this should be a killer portable.

Big payback if the bass is tight n airy..true?

Edit: Been a couple months since I got around to this, but I picked up some Devcon Plastic Weld from the hardware store.  Cost about $5.  There are two tiny screws near the swivel joints of each cup (the ones that allow you to lay the cans flat) and when you undo those and take off the plastic plate, the cup/arm assembly will come off the headband.  Then, you take the arms off each of the cups.  I used a post-it note to mark R and L because there is no ID on the cup itself, just the arm.  Go easy here and use a blade screwdriver to gently pry the arm out at each socket on the side of each cup.

When that is done, mix up the 2-part epoxy - be generous as the unused product in the syringe will more than likely dry out completely be the time you ever get around to the next project at home that needs this glue.  I used half the product in each of the next two steps so that I wouldn't run out in the middle of the routine.  Once mixed, I used a popsicle stick to scoop up a bit of the epoxy and start pressing it into the groove along either end of each arm till each side was full, leaving the bigger center section empty for the time being.  As it sets, it gets tacky but not sticky, so I used a jeweler's screwdriver to seat the epoxy deeper into the groove and then (after a few hours and part one was all dry) back-filled the resulting space in the next step.

Get the four screws and plastic panels ready for assembly because you do this next part quickly.  Orient R and L arms to the proper side of the headband joint (it will be obvious when you look at it).  Mix the rest of the epoxy and fill the center section of one arm completely.  Mount the arm to the brass post on the headband and place the plastic plate in place.  Epoxy will squeeze out so wipe it off, then drop the screws into their holes and tighten them up, wiping off any more epoxy that squeezes out.  Repeat the process on the other side.  With that done, twist the arms around the joint back and forth a few times every few minutes for the next half hour.  This will keep the hinge from gluing in one position.  In the meantime, while the epoxy is still moist, backfill the grooves in the arms to make it nice and level. 

After it all dries (don't forget to occasionally rotate the arms on the headphone hinges) you can mount the cups back into the arms.  If you want, you can shoot some silver spray paint beforehand to make it look nice.  Either way, now the arms are MUCH stronger - effectively solid pieces of plastic.  the original cracks in the arms don't gap, and I am hopeful I won't get any new ones.  Less of the squeaky noises, too!  I'll let you know how they hold up with use.

I recently got these cans due to the generally good reviews but with much apprehensions because of the flimsy bulit arms. But after reading your mod, I decided to try it out. The next day after I got them, I beefed up the arms with steel epoxy and squeezed between the spaces a galvinized anchor / tie wire cut to the length of the arms. I hope this mod would be strong enough for me to enjoy the HP for years and not just months.

And you are right, the creaking stops.

So how's you mod holding up?
post #69 of 70

Sounds like a beefier mod than mine, so hopefully they will hold up as intended.  As far as my mod is concerned, I haven't noticed any new cracks, but the creaking noise has returned, and while that is only noticeable at lower volumes, I tend to listen to most music that way, so it's kind of a deal breaker for me.  Still working with a local fabricator here to convert the cup brackets to solid aluminum.

Thought I'd add a pic of my new Denons.

Cheers!
