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.
