Which explains (in part) why despite not having been a teenager for some time now, I can hear roughly 16 khz or so with no apparent attenuation just fine.This post contains a complete break down of my research and (half cocked) analysis, hopefully this is useful to other people here too.
Denon D2000 Damping Mods Drivers Installed InAssembly Notes: Just go with modifying your preferred cosmetic choice of PowerA Fusion headphones with aliexpress (etc) imported fostex 50mm (32 ohm version) microfibre drivers installed in the provided 3D printed insert and cotton pillow stuffing in the rear chamber, if you just want some best bang for the buck headphones that will blow your metaphorical socks off, and arent too bothered about, or interested in digesting several pages of design intent and analysis.Also I strongly advise removing the internal headphone volume control in the left hand ear cup, bypassing it electrically (its kind of silly, and gets in the way); followed by trimming the plastic supports which held it in place with wire cutters, or your weapon of choice. Then, fill the hole the shaft engaged with with glue to stop the earcup shim from rotating. For Best Results: Use a sound source, or dedicated headphone amp which is known to deliver decent powercurrent to them. Denon D2000 Damping Mods Professional Sound CardsThe in-built headphone amps in some professional sound cards are pretty decent, and some mixers too. I tend to use a portable xDuoo - XD05 headphone ampdac - this is an affordable state of the art XMOSAKM powered soundcard capable of playing back DSD material (if you have it), and can support 384 kHz at 32 bits (in theory, and quite needlessly excessive (you are a bat, right)), and most importantly has massive output power (more than youll need, but the transient dynamics will thank you). Also it can connect to PCPhone via USB, Optical, or a lossless Bluetooth adaptor. Also, it is a mere 200289 for this top shelf product; lesser models, even from xDuoo, are available for around 50-12035-155 with various levels of compromise. You will however, with headphones like these, realise just how irredeemably awful some sound sourcesamps are. However, you can expect them to produce (more or less) the best sound any given device is capable of producing. For sub bass (in particular) that will absolutely rattle your head off, natural dynamics, and clarity up top; be sure to invest in a proper headphone amp, or a decent source. I like having the option of ramping experiencing already prominent extremely low bass sometimes, and having the kick drums and bass drones rattle my head; it has a curious way of engaging you with the material, without annoying the neighbours (were still talking headphones, right ), distorting the overall tonal balance, or presenting any real risk to your hearing - unlike just turning up everything really, really loud. Why would you wantneed a pair: Well designed headphones are the cheapest and most effective route to truly high quality, private listening experiences which negate the need for spending thousands on a studio monitoring grade speaker setup, acoustic room treatment, and sitting in that one optimal sweet spot the entire time to get a similar result. Also, the market is absolutely flooded with garbage headphones (even in the professional realm) which fail to reproduce material faithfully, or satisfyingly. The solution from there on out is to either know the good from the bad (whilst not getting sold snake oil by deluded salesmen) and purchase one of the few commercially available, faithful models at considerable expense. Or, build your own using known good parts for close to the materials cost the manufacturer of such pays. A great test of system dynamics is Eivr Plsdttirs album Slr - It is a curious mix of varied bjorkesue (but much better) Keltictribal sounding music which mixes acoustic instruments, female vocals, massive drums and pins the lot together on a bed of minimal electronic synthery, and general weirdness. She is good, and varied - give her your money) Find a copy in uncompressed format FlacCD, whatever.and then compare it to what the version on youtube sounds like, the difference in detail and dynamics is absolutely shocking. I prefer the version not in English) Whatever your music tastes, you might find something to like about it, its an interesting album. ![]() This translates to a rough median output range (source material dependent) of 60-80 dB SPL at the ear. Which in the background silence of headphones, is perceived as louder than you might think. Generally, its quite safe, particularly if you stick to around that average of 60-80 dB SPL Official guidance on safe SPLs whilst limiting the possibility of long term hearing damage is as follows. Permissible exposure times: 82 dB - 16 hours 85 dB - 8 hours 88 dB - 4 hours 91 dB - 1 hours 94 dB - 30 mins 97 dB - 15 mins 100 dB - 7 12 mins 106 dB - 3 34 mins (yay, fractions - remember those ) For content that isnt heavily compressed, this is my general observation for listening level comfort: 50-55 dB SPL - somewhat quiet. B SPL - normal quiet. B SPL - normal clear. B SPL - getting loud. By that measure, i assume my personal headphone, and other sound exposure tendencies to be generally quite responsible.
