Oh I didn't notice NE5, so didn't try it.

Some very impressive sounding IEMs that I've tried in CanJam Sgp today: BGVP DM8 - Relatively balanced with slight warmness, very nice mids, super engaging. Elysian DIVA - Impressive tuning with 3 level tunable bass level. the mid bass level sounds good for me. Balanced with good spaciousness...

The ATH-CKN50 is meant as a test IEM to help to get consistent insertion depth on every coupler. This is to reduce measurement comparison inconsistency caused by different insertion depth. But not all coupler has exactly the same distance between the nozzle opening to the microphone membrane. We...

For everyone convenience, here is the link to the 60318-4 coupler with good quality ICP mic mentioned above by @csglinux : Taobao link: https://item.taobao.com/item.htm?spm=a1z0d.6639537.1997196601.15.4c197484slCmuU&id=542357654840 Choose option / type : 4 the seller has the 2nd hand B&K 1704...

Balanced interconnections for Pro Audio is not to be mixed up with headphone's balanced connection. The purpose are different. Balanced interconnections in pro audio is to improve noise and interference rejection over long distance connections. Balanced connection for headphone is to double...

If selected, I can provide the original image file without the Earfonia logo. My review of ER2XR here.

No, I mean the calibration / tuning will only work for each specific model. So in practical not an easy way to compare headphone sound and the HATS recording.

We usually called the head shaped microphones as HATS (Head and Torso Simulator). The challenge is probably the difference resonance frequency of the ear canal, between opened and closed ear canal. Opened ear canal during recording will have 1/4 lambda resonance, while when the ear canal is...

Will Sennheiser share measurement of the Sennheiser IE 600 ? FR and THD would be nice. Thanks!

Have you tried to compare the flac and wav files using null test? You can use freeware like DeltaWave: https://deltaw.org/ If there is any difference it will show in the report.

Let's see what do we have here: Symphonium Helios (4-way full BA IEM) - Right - Distortion Measurement - 104dB SPL @ 500Hz: Moondrop Kato (single Dynamic) - Right - Distortion Measurement - 104dB SPL @ 500Hz NiceHCK X49 (single BA) - Left - Distortion Measurement - 104dB SPL @ 500Hz...

Yes that's right! One wire out from the 4 pins XLR to be connected to the 3/5mm / 1/4" unbalanced socket ground pin.

Can, but the ground pin might not be connected. So floating ground which is ok for balanced. You can take the ground from the regular unbalanced output.

I think we all know the basic rule in IEM measurement: In general we should NOT compare measurement result from different type of measurement equipment. Especially the distortion measurement. My humble measurement equipment is no match for GRAS coupler used by Etymotic. I've tried several IEC...

The matte black looks stealthy! Awesome! Is the black one available? :thumbsup:

When BT bandwidth increased to transmit lossless, it is no longer about wireless or wired but more of the tuning of the IEM itself. Even now many wired IEMs tuned worst than some very good TWS. It is always about the IEM's tuning. Wired, wireless, lossless, lossy codec, they don't matter that...

Very interesting! The graph looks pretty close to my IEM preferred target curve:

Thanks a lot! The KBEAR Aurora looks very interesting from your measurement! From your description it seems it sounds pretty good to me. My target for bass response is also pretty close to Harman Target IE 2019. :thumbsup:

Hi KB EAR team and fans, I would like to get some advice. Which KB EAR IEM that has frequency response that is close to my preferred target curve: Thank you!
