Summary: The pana's are interesting to say the LEAST, mids are extraordinary, highs have a good amount of energy, these have the ability to be another asset to the phones overall signature, which is extremely natural, timbre is the best. Now the bass is where these get weird, but not a good or bad weird just weird to someone who's never heard the chameleon characteristics of this particular bass.
Pros: Comfortable, Good Bass, Good Value, Great Sound, Stylish
Summary: hey everyone!
i have this long review in my views regarding the pannys.
i got the earphones today...in me.
and they are just as amazing as my ue700!
but in a different way.
they are colored for me.
there's a lot of echo...air moving...and vibrating inside...something heavy... not the bass...but the overall music. the heavy thing is going to smash into your ears just like that!!! BAM! pushing air and sound into your ears.
for me, its bad.
Summary: Build Quality
The shells made of cubic zirconia is easily the most distinct aspect of the HJE900. It is almost indestructible and according to the literature, can only be scratched by diamond. The shells feel rock solid, has a cool blingy finish, looks and makes you feel good about your buy. The detachable cables with the non-proprietary connectors are a big bonus too. The solid build quality doesn't stop with the shells.
Pros: Tank like build, Detachable cables, Fun & detailed sound signature, Good soundstaging, Decent clarity, Extremely well priced- almost a steal.
Cons: Abysmal fit with bundled tips, Zirconium shells can be heavy, Mesh earwax filters fall out, Springy cable, Slighlty recessed mids, Sparse availability
Summary: These were just the second set of IEMs I bought, the first being Etymotic's 4S about 10 years ago. This was my first purchase intended for portable use (with a Clip +). At first, I was blown away by the low end, not in comparison to a real headphone set up, but to my 4S plugged into a laptop watching Netflix. Hey, I'm just being real.
Pros: good dynamic range, durable, replaceable cables
Cons: tough fit, hard to find, slightly recessed midrange
Summary: PROS: The Panasonic HJE-900 headphones are a very durable, fun-sounding IEM. I would describe the sound as dark, full, with a healthy emphasis on the low-end. All the ranges are present, including a surprising amount of highs. Removable cables make these a good future-proof product. Included silicone ear tips are comfortable enough, but with only average isolation. Use Comply Foam tips for better comfort/isolation. Wearing over-the-ear works well too.
Excerpt: En mi anterior opinión os he hablado un poco de unos auriculares de la marca Panasonic, ya comentada de gran calidad considerada en el mercado, aunque a altos precios hay que reconocer también. Este modelo Panasonic RP-HJE900 es similar al Panasonic RP-HJE700 con las siguientes diferencias que os voy a relatar ahora mismo: ofrecen una sensibilidad de 100dB/mW y una frecuencia de respuesta de 6 Hz a 29 kHz, trabajando con una impedancia de 26 Ohmios.
