Review: Pioneer SE-MJ71 – Swing and a Miss

post #1 of 11
Thread Starter 

Introduction

 

Despite all the time I’ve spent with top-tier headphones and earphones, breaking out a fresh review template for a shiny new product always brings with it a degree of anticipation. I’ve been pleasantly surprised by quite a few head- and earphones over the years and there is always hope of stumbling on the next KSC75 or MEElec M9. My experience with the MJ71, however, can be surmised from the title of this review. Normally upon encountering a product such as this I would shrug, get rid of it, and move on. However, the MJ71 is so incredibly disappointing that I felt it deserved a separate review as a warning to potential purchasers.

 

Packaging & Accessories:

 

The MJ71 comes in a large Audio-Technica-style clear plastic box, which is quite attractive and would make the MJ71 an excellent gift were it not for its numerous failings as a headphone.

 

Design & Build Quality

The polished stainless steel looks are what attracted me to the MJ71 in the first place – stock photos make the headphone look stylish, understated, and vaguely reminiscent of Audio-Technica’s Earsuit line. Unfortunately, there is very little to like about the MJ71 aside from the finish of the earcups. The headband, for one, is completely plastic and suffers from mediocre molding quality. The last time I came across a headband that looked and felt this cheap, it was attached to the $7 Coby CV163. The notched headband extension mechanism feels equally rough and the rotating joints, despite the metal-like appearance, are chromed plastic. Pioneer boasts of the MJ71’s DJ-inspired styling, which presumably refers to the flat-folding earcups and fully collapsible design, but none of the moving parts feel like they will last. The dual-sided cord is also plasticky and cheap-feeling. All I can compliment Pioneer on are the pads, which are nowhere near as sub-par as the rest of the headphone, and the clever red/black color-coded grilles, which act as left/right markings.

 

Fit, Comfort, & Isolation

 

The fit of the MJ71 is typical of a supraaural DJ-style headphone. It clamps a little harder than the MEElec HT21 and gets painful to wear a bit quicker but on the whole is quite tolerable. The earpads are soft enough and don’t heat up too quickly but the plastic headband is unpadded. Isolation is about average for a small closed headphone and sound leakage is respectably low.

 

Technical Specifications

 

Driver Type: Dynamic
Driver Diameter: 40 mm
Frequency Response: 5 Hz ~ 28 kHz
Impedance: 32 Ohms
Sensitivity (@1 kHz): 105 dB
Cable length: 4 ft (1.2 meters)
Input connection: 3.5 mm plug

 

Sound Quality

 

Testing note: All on-the-go listening was done using a Cowon J3 portable player with a wide range of tracks in mp3 (bitrates ranging from 128 to 320kbps) format. Critical listening was done via an optical-fed iBasso D10 using only WMA and FLAC lossless files.

If the construction quality and choice of materials deliver a heavy blow to the Pioneer SE-MJ71, the audio quality makes sure that the headphones stay down for the count. Pioneer offers up claims of “professionally-inspired tuning” and “full, accurate performance”, which are interesting only because the sound of the SE-MJ71 is colored in ways I’ve never heard before. Not saying that the tuning wasn’t inspired by a professional – perhaps just not an audio professional.

The MJ71 has three major weaknesses – bass, treble, and presentation. The bass is forward, deep, and strong but tends to lack control and clarity. I’ve certainly heard worse but not from something with an $80 retail price - the Pioneers are only a little tighter at the bottom end than the fashion-oriented Coloud Colors. What little control there is drops even further once several instruments are in play due to the poor resolution and driver speed – the MJ71 just gives up and falls into a muddy abyss when the track gets busy. An additional issue is a strange echoing/resonance against the earcups heard on strong bass lines. Overall not a very realistic bass experience.

The midrange is clearer and less offensive on the whole than the low end. The bass is strong enough to make the balance seem slightly skewed away from the midrange but overall the MJ71 is a forward headphone. It manages to pull away from the veiled and muddy sound of the Coloud Colors in the midrange but sacrifices a bit of the smoothness as well. The upper midrange and treble are quite prominent and the MJ71 isn’t warm or thick-sounding. The highs are bright and slightly thin, leading to a ‘tinny’ sound. There are some narrow treble peaks that cause the MJ71 to sound overly harsh with certain tracks. It is a fatiguing, shiny, metallic sound that doesn’t sit well with me at all. I still prefer the balance of the MJ71 to something with severely rolled-off treble (e.g. the UrbanEars Plattan), but only just. Treble roll-off still occurs slightly earlier than one would expect considering how aggressive the top end is on the whole but the headphone does not sound dark, dull, or stuffy. Still, the presentation is aggressive and congested. The soundstage is smaller than with the UrbanEars and far more confined than with the similarly-priced MEElec HT-21 or Sennheiser PX90.

 

Value & Conclusion

 

I wanted to like the SE-MJ71 for its looks and portability but from the very first listen I've felt that Pioneer missed the mark by a mile with the $80 MSRP. Prices have been dropping across the board over the past couple of months but even at a third of the original price I still don’t see a competitive product here. The construction quality is underwhelming and, aside from reasonably clear mids, the sound quality is sub-par. My advice – look to Audio-Technica if you are attracted by the cosmetics of the MJ71 or to alternatives that were well-priced from the start if you’re attracted to price. Sets such as the MEElec HT-21, Denon P372, Sennheiser PX90, and Koss PortaPro will walk all over the Pioneers without having to be massively discounted. Not recommended.

Tell us how you really feel. I'm sensing you might not be so fond of these headphoneswink.gif.

You can tell by the title itself that he didn't.  You can also tell from the tone that he uses through the review that he doesn't like them as well. It's more of a disappointed tone from how I interpreted it.

I tried to sugar-coat it, honest biggrin.gif

"the MJ71 is so incredibly disappointing that I felt it deserved a separate review as a warning to potential purchasers"

 

Yeesh. I guess I'm glad I didn't buy these the couple of times they were available on Woot.

LOL, sugar-coating anything never works to make it sound good :p  Subconsciously your tone and word choice will come through to tell the audience how you feel, even press reps can figure it out :p  It's hard to say something isn't good in a nice way, in some sense, it really isn't possible since the audience knows you're beating it around the bush.  Well, at least we know you have some empathy :)  Nice review by the way, I'll be staying away from these :p

Thanks for the heads up, never been a fan of anything Pioneer, especially their car audio line.

Exactly what I remember from trying them out at Yodobashi camera and BIC camera electronics stores in Japan. Very tinny sound. Not really worth the 5.000 yen that they retail for. Still I saw quite a few of them while commuting during the year I lived in Japan...

 

I remember preferring the JVC HP-S360 and 560 to the Pioneer SE-MJ71.

 

While in Japan, I bought a pair of Pioneer SE-EX9 clip on earphones and they sound very good. Just as on the SE-MJ71 the treble is slightly thin which gives them a somewhat tinny sound, but far from the amount on the SE-MJ71. Overall I find the SE-EX9 to sound very good. Too bad that they are discontinued.

I did frown.gif. Can't believe I even thought about buying several without listening to them first. I wouldn't have even been able to get rid of this one pair if someone didn't need some portable shells for an ortho transplant (because obviously they can't be sold/traded as 'headphones').

Bright/thin can be done reasonably well, e.g. with the Sony MDR-Q68 or ATH-EM7. The EX9 probably belongs to that category as well. The MJ71 is too aggressive for that sound to work, though. 5000 yen is at least 5x too much. I'll take a Coby CV185 over these any day.

Wow seriously??

I own these and have been using them as my portable headphones with my iPhone 4 for the past year. They are the best portable headphones available, imo. They sound great, and I mean that as in sound like mini versions of my Beyer DT 770's. They are small and light, comfortable, fold out of the way dj style and look COOL. Perfect for wearing around all day. What do you expect from them? they are as good as you can get for the size and price. I have nothing bad at all to say about these. They rock! they are exactly what I looked for for over a year. I travel the world for my work, and I take these everywhere.

Guys, don't be fooled by this review. Try them out and see for yourself. Just look at the specs... they ARE good!!

Pioneer makes some of the best stuff. I have a Pioneer cd player in my car as well, it's amazing.

So, what do the specs tell us?  How do the specs show that the headphones are good?  Just because a company makes one good product (in a different category) doesn't automatically mean all their products are good.
