1/4 TRS phon plug SHURE SRH series (SRH440/ SRH740DJ/ SRH840/ SRH940)

The bayonet clip structure made of PBT

The bayonet clip structure of SHURE SRH series was produced by almost a micron of accuracy and repeated adjustments in order to obtain smooth and strong holding property. The hardness optimized material, PBT, holds headphones properly and don't abrade away the locking part of headphone itself. The outer cover made by chrome-plated brass has knurling which makes grip easier and enhances beauty of the HPC-35SRH/HPC-62SRH.

PCOCC-A high quality HPC-22W cable

For the cable of HPC-35HD598/62HD598, we applied Oyaide original HPC-22W which became a standard of headphone cable. By its high-quality PCOCC-A conductor, electrically superior PFA insulator, flexible and rigid TPE outer sheath, it has great sound quality and usability.

2types of length, 2 types of Audio plugs

In order to respond to various using situations, we prepared 2 different length (1.3ｍ/2.5m) and 2 different kind of plugs (3.5mm stereo mini and 1/4 TRS phone). For both plugs, we applied silver + rhodium combination plating which has been proved its superiority by application for other HPC-series.

Audio grade solder, SS-47

We use our original audio grade solder, SS-47 for the connection of plugs and cables of HPC-UE. Compared to general solders which usually contain 3N (99.9%) pure tin, SS-47 contains 4N (99.993%) pure tin achieved by excluding impurities to the maximum. Furthermore, 4.7% silver and 1.7% copper are contained for the purpose of improvement of electric conductivity and durability.
