Panasonic RP-HJE900 IEMs Use Zirconia to Allegedly Improve Sound

zirconia iems Panasonic RP HJE900 IEMs Use Zirconia to Allegedly Improve Sound

Until now I thought I’d heard about every possible method of allegedly improving sound quality on IEMs, but I was wrong. While some IEMs have quad armatures and others have interchangeable parts, Panasonic have taken it one step further and have included a Zirconia in their RP-HJE900 IEMs to “suppress sound distortion”.

The RP-HJE900 also comes with interchangeable cables through connectors that frankly look more like Nokia chargers than audio jacks. The phones have a frequency range of 6Hz–28 KHz and an impedance of 26Ω. If the use of this material really had an effect on sound quality I’d have thought the bigger IEM manufacturers like Shure or Ultimate Ears had already tried it so I don’t have too much hope for this product, but it sure would be interesting if these got good critics. The IEMs will be released in Japan on June 15th with
no word yet on pricing.

Interesting… but they will likely be way overpriced and not worth comparing to other IEM’s of that range.:-(Cans are ftw anyway; less microphonics, faster on/off, better sound to price ratio, etc…If you don’t mind some 4″ circumaurals hanging from your neck =D

Yeah right… 6Hz. And pigs can fly.

Huh? 6 hz? That’s approaching the Brown Note. I’m going to have to reconsider whether they’re such a good idea or not.

Check price at warehouse123 is about $200 and it’s a bit less than my expectation. It’s the best earphones of Panasonic now, very good bass and it’s comfortable to the ears.

I know this is an old read but I actually posted a review on these awhile ago on head-fi. There is truth to the marketing believe it or not.
