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. All of this coming out of a small headphone. All the specs are good, and I couldn't believe these were 32ohm. Awesome!
They are "on ear" but they nearly cover my ears, which is great.
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. 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.
Pros: Clear and defined tones, portable, great design
Cons: Short and thin cable, fragile looking shell, easily destroyed jack-cable connection
Summary: Acabo de comprar los auriculares Pionneer SE MJ31 por unos 30 y tantos euros, y estaba dudando entre estos y unos senheiser de unos 60 euros, y me decidí por estos porque los quería cerrados y porque las especificaciones técnica eran superiores a pesar de ser twn baratos. Bueno la verdad es que no he escuchado muchos auriculares de esta gama, por usar siempre los de boton, y he alucinado con el sonidos, los bajos muy pontentes, los agudos cristalinos y aíslan muchísimo.
Pros: Graves, agudos, aislamiento, poco peso, plegables, precio
Cons: Material de plástico, No son de cuero real .
