Upgrade from cheesy headphones with the AKG K81DJ, a great-sounding on-ear design for use with iPod, iPad, turntables and computers. Delivering meaty bass with enough mids and highs for proper musical balance, this durable headphone isolates from the noisy ambient world with comfortable sealed-back earcups while delivering precise sound Right Between Your Ears. With sturdy build, big tone and tidy travel foldability, the K81DJ stows well in a backpack or carry-on until called to action.

The AKG K81DJ is a wonderful move into great sounding, closed portable headphones without suffering a painful billfold blowout. Perfect choice for mobile listeners, beatmakers, DJs, and computer / iPod / iPad music, expect smooth midranges and upper highs riding alongside a beefy but surprisingly well-focused bass response. The K81DJ tone remains a hair rolled-off in uppermost treble extension, but the low-end sounds more tautly textured versus 'bargain' headphones, meaning not as boomy although it still remains slamming enough for most big bass lovers. The ambient noise-blocking seal of the K81DJ is effective at attenuating noisy environments while preventing headphone 'leakage' to the outside, a must if listening in quiet dorms, cubicles or libraries without disturbing neighbors. The K81DJ efficient impedance and sensitivity specs makes it suitable for use with any source like iPod, iPad, MP3 players, club decks and laptops. However, a good (portable) headphone amp makes a great partner for the K81DJ to improve clarity, dynamic range extension and musical detail resolution, most notably with portable/mobile audio sources and laptops /notebooks.

The AKG K81DJ has a simple pro look without much outsize bling -- nice for laying low without your cans attracting undue attention. The mid-sized 'supra-aural' [on-ear] earcups typically rest on the outer earlobes with pleather-covered earpads that rotate 180 degrees for fast-paced DJ 'mono' mixing with one ear -- or for just keeping your head on a swivel when you need to remain aware of your surroundings. The earcups fold into the headband for ease of storage & travel. The K81DJ headband design is a lightweight but beefy rubberized/metal combination that feels very durable and secure on the head. The clamping force of the headband may perhaps prove an issue for big noggins, but you can try gently bending the pliable headband (gently!) for a more personalized fit; [HeadRoom Tip #221: Letting the headband stretch while clamped on a basketball or over a thick stack of books for several days helps alleviate the tight fit]. Most sizing adjustments are simple and effective via the K81DJ headband slider mechanism. The AKG K81DJ 'Y-type' cord extends approximately 8ft, terminating to a gold-plated 1/8" [3.5mm] 'mini' plug. Included is a 1/4" full-size 'screw-on' adapter needed for stereo receivers, home CD players, studio mixer consoles, etc. A handy carry/ travel/storage pouch completes the package. The manufacturer's 2-year product warranty remains free with all AKG headphones when proof-purchased at authorized AKG dealers -- like us here at HeadRoom since 1992!

***After modded*** are very good & very cheap!
Posted by Datman from Roma, Italy on 2012-01-25

Recommend Product: Yes
Pros: Very good isolation; after modded, sound is well balanced, rich, crystal clear!
Cons: Cable is very poor and two-sided. I replaced it.

Years ago I bought a AKG K518LE. By the published measures it seemed to have a good response. As I found written in Internet it is equivalent to the AKG headphone K81DJ. When I got home I realized the sad reality: a very large amount of low frequencies ! There was also a clear resonance of the box at a few hundred Hertz.

Graphs published on this site seem to be mismatched with another headphone. Frequency response is very different from the graph. Low frequencies are very stronger than in it and isolation graph is the typical one of an open headphone...

I did many tests, until I came to the final solution: two tufts of wool within each can and, there, also a little 10uF capacitor with 47 ohm 1/8W or 1/4W in parallel, all in series to the speaker. The capacitor should be a bipolat type, but an electrolytic one works also well, with no reguard to the polarity. Also a small smd tantalum 47uF/16V parallelepiped capacitor salvaged from an old hard disk will be useful. After these mods headset sounds really good, with a correct sound, crystal clear, powerful bass but well balanced.

I find the K518 more comfortable than the classic K141; used with the MP3 player in the winter it protects the ears from the cold but in the summer makes you sweat a very little, because it does not protrude much from the pavilion. The sensitivity, even after modification, is also good for a mp3 player.

Cable is very poor; I have salvaged it from an old HD40. Now it is very good!

***ITALIAN original version:***

Anni fa acquistai una AKG K518LE, che dalle misure pubblicate sembrava avere una buona risposta. Per quanto trovai scritto in rete tale cuffia è equivalente alla AKG K81DJ. Quando mi arrivò a casa mi resi conto della triste realtà: una quantità di basse frequenze che coprivano tutto il resto! C'era anche una evidente risonanza della "cassa" a qualche centinaio di Herz..

I grafici pubblicati in questo sito devono essere stati scambiati con quelli di un'altra cuffia. Nonostante la mia segnalazione, però, noto che non sono stati cambiati. La risposta in frequenza è molto differente da quella riportata nei grafici. Le basse frequenze sono molto più gonfie, al punto da coprire tutto il resto, ed il grafico dell'isolamento è quello tipico di una cuffia aperta...

Feci molte prove, finché arrivai alla soluzione definitiva: due ciuffetti di lana di vetro all'interno di ogni "cassa" (auricolare) e, sempre lì dentro, un condensatore da 10uF con 47 Ohm 1/8W o 1/4W in parallelo. Il condensatore dovrebbe essere non polarizzato, ma funziona bene anche un elettrolitico comune comunque orientato. Va bene anche un piccolo condensatore smd al tantalio 47uF/16V a forma di parallelepipedo recuperato da un vecchio hard disk. Dopo queste modifiche lu cuffia suona veramente bene, con un suono corretto, limpido, cristallino con bassi potenti ma equilibrati.

Trovo la K518 più comoda della classica K141; usata con il lettore mp3 d'inverno protegge le orecchie dal freddo ma d'estate fa sudare poco, in quanto non sporge molto dal padiglione. La sensibilità, anche dopo la modifica, rimane buona anche per un lettore mp3.

where are the highs?
Posted by Zobel from Montana on 2011-11-08

Recommend Product: No
Pros: only slightly overpriced
Cons: too much bass, not enough highs, too small to fit comfortably

These are not a good value due to lack of high frequency, and poor fit. Too much of anything is not a good thing, and there is way too much bass with these phones. I didn't find Headroom's frequency response graph to be at all representative of the sound of these phones. They are too small. I wouldn't recommend these to anyone.

Good bass
Posted by bla4444 from debrecen on 2011-07-19

Recommend Product: Yes
Pros: Good suond
Cons: Uncomfortable

This headphone is for bass lovers. The whole spectrum is quite good. The problem: Very tight headphone, and altough it not so uncomfortable as the deno9n ah p 372, it is hard to use for hours. The soundstage and the is better on headphones like aht sj5 or denon ah p 372, but the bass is weaker on them.
