Summary: I was in Japan and was looking at headphones to buy. I had a cheap budget of about 4000 yen or circa $40. I bought this headphone because it was on sale for $30 and was very good looking. It was also labled as a bass heavy headphone which attracted me at the time.
Summary: I bought these for portable everyday use, and I can't say enough good things about them. They are perfect. The sound is amazing. I have Beyerdynamic DT770's and these sound like small versions of those. These have very punchy bass and nice mid and treble, with beautiful sound stage.
Summary: I got tempted to purchase a pair of these after reading the reviews here and seeing these cans appear on a bargain site (Catchoftheday.com.au). They perform well, but I prefer the sound of my ATH-M50's, but for the money they are a huge step up from anything else I have used in this price bracket.
Summary: 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.
Pros: Clear and defined tones, portable, great design
Cons: Short and thin cable, fragile looking shell, easily destroyed jack-cable connection
Excerpt: Le Pioneer SE-MJ31 est un modèle de taille moyenne, à la fois sobre et discret. Sa finition a une allure un peu économique, mais les enjoliveurs en faux aluminium brossés rehaussent le ton même s'ils se rayent trop facilement.
Pros: Les oreillettes repliables, Rapport poids/gabarit, Un son moelleux
