I have to send my Westone ES5's in for service and noticed that they've updated their ES line to include an extra 0 after the model numbers and also that they're using the Shure style MMCX connectors now. While talking to the guy at Westone, I asked if they could swap out the 2 prong connectors for the MMCX connectors. He said they could for $250 which would include a new cable (iDevice mic/remote if I wanted).
I've been using the 2 prong connectors since around 2008 and to be honest, I've been tired of them for a long time. The Westone cable and connectors have been the most solid and only cable that has lasted over a year and never gotten loose. However, lack of a decent iDevice remote/mic cable or adapter combined with failure prone (on average) cables and connectors is making me think about doing the upgrade.
Anyway, does anyone have a good comparison or opinion on the MMCX (I've always considered them the "Shure style") vs 2 prong (UE/JH/Westone) connectors as far as usability, durability, how well they hold, etc.? Think it's a worthwhile upgrade?
