Shure’s Remote + Mic Lightning Accessory Cable or RMCE-LTG features a premium inline digital-to-analog-converter or DAC and stereo headphone amplifier
for use with any iOS device (iPhone, iPad, iPod) with a Lightning® connector.
This has an Apple-certified Lightning Audio Module with a three-button remote (volume up/down, hang up/call) and
a separate mic module on the right ear cable close to your mouth. This cable system enables digital audio playback with simultaneous cell phone operation. The RMCE-LTG is the first with MMCX earbud connectors, providing digital iOS compatibility for all detachable Shure SE Sound IsolatingTM earphones.
Shure also has the analog version called the Remote + Mic Accessory Cable RMCE also designed for detachable SE earphones but for conventional 3.5mm TRRS connectors.
I tried the RMCE-LTG with a pair of Shure SE215 earphones, but you should know that both the LTG and analog cables work fine with the SE315, SE425, SE535 and SE846 earphones too.
I use an iPhone 6 (iOS 10.3.3) and the lighting connector has digital audio available and there was plenty of volume com- pared to my other analog (only) earphones. The SE215’s are comfortable to wear and I liked the sound and operation of the DAC. The Shure RMCE-LTG is made well and they have a clear and warm sound.
The analog Remote + Mic Accessory Cable (RMCE) sells for $29.99 while the Remote + Mic Lightning Accessory Cable (RMCE-LTG) has a retail price of $99.99.
