Noble Audio XM1

General Information

noble4_1024x1024.png

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.

Well, I finally see it listed on the Noble audio site:
https://nobleaudio.com/products/xm-1

Interestingly, my first set came loose at the iem housing the 4 point connector, but the amazing guys at Bloom immediately sent a replacement. But the replacement arrived with a new issue, the left ear nozzle just popped out from the iem body (bad glue I guess), which again needed to be replaced. Call me unlucky, as both Bloom and Noble support mentioned nothing similar has been reported on the XM1. So on my 3rd set now and all good. Just hope it lasts, a long long time :xf_cool: , continue to love the IEM, the sound, the versatality and the excellent support from Bloom and Noble.

Just got these in, not enough time yet but so far for Electronic music these might be the ticket for on the go listening. Will put more time into them and then I will return with more thoughts.

These are REALLY good for Electronic music, I mean really good, details in both Low and High Frequency Response is SUPERB, the soundstage is very wide and deep, some of the largest soundstage in IEM’s I have encountered.

I am listening at present with my Fiio M23 as a source in DAC mode, and the only thing I have that I am finding bothersome so far is that with all three devices I have used on these XM1 (iPhone 15 Pro Max, new M4 iPad Pro, and M23 DAP) is that I have to have the volume at 75% or a few clicks more, I am not used to that and while the sound doesn’t thin out or anything it is just a small thing that is different than I am used to with conventional IEM’s or Headphones……typically I would be looking for a more powerful amp at this point to be sure I was powering the outputs properly. @NobleAudioMKTG if you have an any input if this is normal then that would be appreciated/\.

I noticed as well that they don't go very loud. The xMems needs a "high bias" amplifier. The AIO approach is the best we can get at this point.

I think we are stuck with "just enough" loudness.

Did you try using UAPP and try playing with volume settings for USB output?

I guess you tried ear tip rolling? I"m current using the dual flange large size for proper isolation, and I get sufficient volume around 50% ( Android 14, Galaxy flip5). With the divinus I realized I was losing some of the low end.
