Introducing Noble Audio's first implementation of the new xMEMS driver technology, the Noble XM-1

Noble Audio XM-1 xMEMS Driver In-Ear Monitors Front View

Until this point, wired xMEMS technology has been limited due to the need for a specialized high-bias amplifier. In order to expand the accessibility of the xMEMS drivers and their unique sound signature, Noble has incorporated the high-bias amplifier into the IEM itself which eliminates the need for additional equipment to enjoy them. The XM-1 can be used with any smartphone utilizing a USB-C port or an Apple lightning port when the included ddHIFi lightning to USB-C adaptor is used (TC28i).

To power the XM-1 and the integrated amplifier, we went with an active USB-C high-quality cable with a 4-pin connector. Intended use is for smartphones with USB-C ports lightning ports, or other smart devices that allow for USB-C listening. Note that DAPs that have USB-C ports may require changes to settings in order to allow volume to be controlled through the USB-C port. Also, note that the XM-1 is NOT compatible with the Astell & Kern DAPs due to AK's use of an abbreviated Android OS.

The XM-1 features the xMEMS Cowell tweeter paired with an 8.3mm Dynamic driver for the low end. The resulting sound is astoundingly clear mids and highs as is expected with the xMEMS Cowell, coupled with full bass extension, which has previously been lacking in xMEMS products.

The Noble XM-1 is designed to be robust to keep up with users who are listening on their mobile devices. The aluminum shell with stainless steel nozzle and wax guard helps to make sure that the IEMs are able to keep up with busy daily use.
