I attended CanJam Singapore 2022 last Saturday and tried some IEMs. Just want to share some IEMs that to my ears sound really good during the short period of testing. Didn't manage to test all brands and models as there are too many of them, but from what I've tried the following IEMs worth a...

https://www.sony-asia.com/electronics/in-ear-headphones/xba-z5 A friend drop-shipped Sony XBA-Z5 to me for measurement. I took this opportunity to write a short review of the Sony XBA-Z5. MSRP: $631 Launched in 2014, Sony categorized the Sony XBA-Z5 as Sony’s ‘High-Resolution’ audio product...

Already postponed for 2 years, hopefully this time It's on! https://www.head-fi.org/threads/canjam-singapore-2022-april-2-3-2022.922817/

https://www.etymotic.com/product/er2xr-earphones/ Etymotic ER2XR (Extended Response) is one of my favorite IEM from Etymotic that doesn't need any introduction. I bought this pair from a local shop around 2 years ago. It is a deep insertion micro dynamic driver design with almost ruler flat...

One of the main objectives of In-Ear Monitor measurement (as well as other audio equipment measurements) is to understand the correlation of the perceived sound quality with the numbers and graphs. I’ve been doing IEM measurement for a while now, just as a hobby, to learn how to correlate what I...

Hi! I would like to get some help with REW Export distortion data as text. I've read this help section: https://www.roomeqwizard.com/help/help_en-GB/html/file.html#filewritedistortion But in my case I got weird numbers in the THD (%) column. The value in the THD (%) column in the exported text...

During RTA measurement in REW, I noticed that the noise floor erratically jumps up for unknown reason. This happens on my In-Ear Monitor measurement setup as the following: The whole equipment in the setup is placed in an noise isolation case with thick dense rubber mat around the case wall...

My journey in In-Ear Monitor (IEM) measurement started with some common measurement microphones and DIY shrink tube couplers. I've been interested in IEM measurement for quite a long time, but not ready to spend big bucks on GRAS or B&K couplers. The idea is to search for a more affordable...

I recently bought Etymotic ER4XR and I found the level for sensitivity measurement seems to be wrong. In Etymotic website the sensitivity or ER4XR should be around: Sensitivity (@1 kHz) SPL at 0.1v : 98 dB https://www.etymotic.com/er4-micropro-earphones.html Sensitivity (@1 kHz) SPL at 0.2v ...

This topic is related to In-Ear monitor measurement and review, so I posted here in this sub forum. My attempt to calibrate the SPL reading of my 'AliExpress' IEC 60318-4 compliant coupler with the common ND9B SPL calibrator: Similar to the 'Level Calibration' procedure in this GRAS...

I've had several discussions with local Singapore brand of In-Ear Monitor, kind of a small startup company, about In-Ear Monitor measurement. Since this is for formal publication of their measurement, we prefer not to use 'brand-less' IEC 60318-4 coupler kits from China, but a more 'proper' IEM...

I've been playing around with measurement of In-Ear monitor Impedance Curve using REW Impedance measurement feature. Many thanks to @JohnPM for the great software! So here I just simply want to share my setup and things that I've learnt so far. The setup: Audio Interface: RME Babyface Pro...

Recently I bought Yinyoo IEM cable for TFZ T2 during AE 11-11 sale. I bought it simply for the look as it looks nice and matching the TFZ T2 blue color. When I compared it with the stock cable, I didn't expect to hear any differences, but I think I did hear a slight differences between the 2...

Hi All, newbie here looking for some measurement guidance. Hopefully I post this topic in the right place. I have QuantAsylum QA401 and I borrow my friend's RME ADI-2 Pro. I would like to measure the SNR and SINAD of the line output. The setup is as the following: ASUS Laptop USB C with foobar...
