An old thread, but still quite relevant. True, most of the reviews about the Pioneer HDJ-X10 are from club DJs. While I am a DJ (radio, mobile and the occasional club gig), I am also a consultant, producer, and audio engineer. My daily drivers are the Sennheiser HD650 and AKG K702 for mixing, Beyerdynamic DT770 and DT100 for tracking, and the Pioneer HDJ-X10 for DJ stuff.
Online reviews of the HDJ-X10 illustrate the emerging uselessness of the internet. There’s a review for every opinion. If you like these headphones, there are reviews about how good they are. If you don’t like them, well there are reviews for that as well. And some of the reviews are obviously not genuine first-hand accounts, but compiled from other reviews simply to populate websites. I have seen this comment more than once: the HDJ-X10s are too good for DJ work. But this raises an obvious question: what sound quality do they normally blast at their clients? It’s like saying a BMW M5 is too good to drive on public roads. That said, here are my thoughts on the Pioneer HDJ-X10.
Sound
The sound of the HDJ-X10 is as good as it gets for DJ shows both on the radio and on the road. Looking at the graph in SoundID Reference, they measure a 3db bump between 50-300htz, then slope gradually down to minus 6db at 5k, and back up to within 3db of flat from 8k up. Pioneer DJ did an exceptional job tuning these headphones for DJ/producers. They are rated at 3.5 watts max, which means they should stay clean well past eardrum destroying levels. However, I can’t corroborate this particular fact.
The HDJ-X10’s party piece is the soundstage. The soundstage is quite wide. Most people on here will know this, but if you don’t, the wider or bigger the soundstage, the more it sounds like you’re listening to speakers in a room. For comparison, the K702 mostly achieves this effect, the HDJ-X10 not quite, but it’s close. The HDJ-X10 has the widest soundstage of any closed back headphone I have ever used. The soundstage, combined with the recessed hi-mid / low treble, makes them non-fatiguing and excellent for long radio shows, live DJ work, tracking and casual listening.
In the final analysis, the bass is a bit embellished, and the low treble is slightly backed off, but they are flat enough for many applications other than beat mixing. Pioneer has made a good compromise in tuning the HDJ-X10: kind of halfway between a traditional DJ headphone and a modern audiophile/studio headphone.
Durability
The HDJ-X10 are made almost entirely of aluminum, Pleather and steel. Again, many online reviews say, “mostly plastic build.” Clearly, they have never had these headphones in hand, but rather copied misinformation from other reviews. The only visible plastic parts are the housing covers on the back of the aluminum yolks and steel headband adjusters. And the milled aluminum ear cups have nice rubber grips and bumpers. There is a video review of the X10s durability called “Destroying DJ Headphones - PIONEER DJ HDJ-X10,” if you’re interested. Overall, a great build, not DT100 durable, and you can’t replace the parts, but still very good.
Comfort
The pads are 90mm (DT770=100mm, K702=110mm, etc.): my ears just barely fit. Inside the pads, my lobes brush up against the nylon covered driver housings, which is a bit annoying. However, I can wear them for a few hours without needing a break. Again, online reviews vary from award winning comfort to extremely painful. I would rate the comfort as acceptable as long as you don’t have big ears.
Conclusion
The HDJ-X10s are excellent headphones, but are they $350 USD excellent? With the great build, nice case, and superb sound quality for the intended purpose… yes, absolutely.
Alternatives
As of posting, I can’t think of any direct competition. The HD25, M50X and TMA-2 are not in the same league. As one post said, if you get these, you will be spoiled. The K371 is closer, but lack of soundstage and boosted treble make the AKGs more for suitable for tracking. The V-Moda M100 Master are quite durable, but have an old school DJ sound profile and useless cables (FYI: if you do buy the coiled cable, it doesn’t fit in the case).
HDJ-X7 vs HDJ-X10 Comparison
In pictures these two headphones look very similar, but in hand the X10s have a more robust build all around. Aside from the headband, which appears to be identical on both except for the nano coating, every part on the X10 is more substantial. The X7 sounds great, but has the classic DJ sound profile: accentuated bass and a treble spike at 10K (booming lows and loud hats). So, if you’re a club DJ, perhaps the X7s would be a better choice as they are much more like the HDJ-2000 MK2 they replaced.
Cheers.
