These things are HUUUUUUUUUUGE for what they have underneath.

It's probably an overstatement because this monster of a headset isn't all it's really cut out to be.
It's produced and advertised by Razer as a "Gaming Headset". In that assumption alone there's already a misleading information. For a pair of cans to be a gaming headset they need to have good output sound as well as good input sound. It only barely falls under one of the two.

THE LOOK

Okay, like I said in my opening statement, these things are HUUUUUUGE! The shell is something I've come to love from my use of these things but otherwise, it's only there for aesthetic purposes. The headband looks thick and comfy, which it is, but it's a clever ploy for something underneath. Feeling through the faux leather encasing the headband, you can clearly note that there are two thinner bands sandwiching a plastic/metal strip. Very clever, Razer, very clever. The housing of the drivers looks to be in a HUUUUUUUUUGE plastic shell, another clever optical illusion. The cups are actually in two parts, the ball and socket like driver and ear cup housing and an outer case containing some padding for added comfort of the driver housing being pushed back to conform to your head. The hinges are nice and the cans fold up in the usual manner. The cups though do not swivel from the hinges in a rotary manner, they only fold up inwards.
 
THE SOUND
 
Punchy is the only thing I can state the sound quality with. The bass and overall reverberation of these pair are above par. Already suitable for gaming purposes leaning towards game immersive experiences like Amnesia or Silent Hill for example. The thumps and the vibrations can drive you mad if you're listening to those horror themed things, great for ambient sounds as well as defined movements. So it lives up to good gaming audio, is it good for audiphile purposes too? No. The reason for this being that they put so much of the effort into the bass they forgot about other tones, mostly the mids. Vocals from any genre as well as some defined instruments like strings and pianos are too recognizable but too soft. For gaming purposes like listening to footsteps and ambient noise it's good, but for songs, it's like turning down the volume for the vocalist or the guitarist to the lowest recognizable decibel.

THE CONCLUSION
 
This is a pair of Gaming HeadPHONES. yes, HEADPHONES. reason why? The mic isn't cut out to be even considered a microphone. Think of the oldest mobile phone still alive, try receiving a call from that phone. The quality of the recording module just isn't that good to be considered for gaming especially when you need to yell out specific orders to your team mates without prior misunderstanding. 

The comfortability of these things is sub par. Even for an Asian with a presumably smaller head size, these things hurt in the long run. The band notches are adjustable but the tension on it is just too tense sometimes. Oh and leather, LEATHER! Gets warm quicly especially since, well, it's black. Out in the sun you're just baking your ears.

Are they worth the price point? Honestly, no. One of my earlier cans, an ATH-WS55 costs about the same price here in my country and the biggest differences are that the Electra is comfier but the AT has MUUUUUUUUCH better sound quality, although less vibrations due to the design of the units (the removable cable is one too but I don't mind cables that much since I clutter everywhere anyway). 

 

First off, looking at the packaging, it's not all that. It promises a range of 8 Hz - 25K Hz and frankly, it's kinda much of an over specification. Even if you can feel down to 3Hz minimum, it doesn't even practically apply to any sound besides binaural sound waves. But it is a good advertisement for what it is aiming for, bass heads. I got myself a red pair along with the HDJ 500 I currently use. Given that it was a promo item, I was thinking, maybe it's not selling that well. So I decided to burn it in and see for myself why no one would want a pair (cause frankly, even among my peers, some people don't even know Pioneer made cans like these).

Note: I didn't get the LOOP one, just an ordinary SE-MJ31, I don't know the difference so yeah... :v

THE LOOK
 
Okay, first, basic concepts of headphones. Must have a headband, must have two cups to contain drivers, must have a cable to direct the audio signal, must work. These are all necessary implements of any good headphones that I can definitely say these pair of headphones have. When I first unboxed them and got a proper hold of them, the first thing that got to me was how light it was. "Hmm, maybe the drivers are really just 30mm." I was wrong (to be discussed in 'THE SOUND'). Another thing that caught my eye was the lack of padding on the headband. It's a small compromise of comfort but what would you expect from something <$50.  The cable is also something I  took a note on. Very thing cables sprout to the drivers, the Y design cable the sprouts of (1.2 m length) to a straight 3.5mm jack. Again, <$50. They could've done better though.

So it wasn't looking very much like a good value pair from the get go.
but.....

THE SOUND
 
I burnt them in for a good 30 hours with the usual wave tests from a basic home setup. I put them on and went with the genre runs from my mobile. First off, metalcore (with its grungy chugs and wide range of vocals). I was stunned, right there and then. The crispness of the highs and the defined mids just got to me. The bass though was a constant reminder for what these were originally meant for, bass heads. It wasn't that punchy but it also wasn't just a back ground fade like I've come to know from some disappointing cans. 
 
Going through the different genres in my playlist, the same was the result. Surprisingly good audio (but then again this is Pioneer we are talking about so it's not all too surprising) for the price point. These pair of cans have one of the more toned mids of any cans I got, like ever, even compared to its cousin the HDJ 500 which is known for having the one of the most equal ranges of any "DJ Monitoring Cans".

THE CONCLUSION
 
These pair of headphones, summed up in one statement, satisfyingly nerve tingling.
The design is not that good to be honest, the main use of plastic and the leather on urethane ear pads wasn't much of a good impression when looking at them. But the sound just makes you forget about the design. Although you don't get professional audio quality (no, this is nowhere near to proper studio cans) the sound is just something you can gawk at. The design of the casing of the drivers may have something to do with that, but the drivers (32 ohms, can you believe it?) are just great. 

At the sacrifice of comfort, which is not really much but since it's on-ear and has a plastic headband, you get a good pair of cans.

I can recommend this for anyone on the go, anyone who  doesn't mind the discomfort of the plastic rubbing their hair/scalp and the fast heating qualities of leather.
