    Audio Measurements on a Headfi Budget

    In my experience, you'll find the calibration files offered by AE and Taobao sellers always fall into one of two categories: 1) completely useless or 2) non-existent.

    Audio Measurements on a Headfi Budget

    IMHO, smoothing is always preferable. Let's say you've compared measurements from an identical IEM. Your coupler gives a resonance peak at 7 kHz and the GRAS RA0045 gives a peak at 7.25 kHz for an identical insertion depth. If you just take the difference between those two curves and apply it as...

    LG V40 ThinQ

    The M11 Plus ESS is an excellent DAP. (The original M11 wasn't - so be careful to buy the ESS version.) There's a small article on this here: https://www.hypethesonics.com/fiio-m11-plus-minihype/ @Thieftime - if you can do your own listening tests, try to listen blind, SPL-matched and have a...

    LG V40 ThinQ

    You're not wrong :) UAPP (and Neutron, which was actually the first app to figure this out) bit-pads to get from 16 to 24 bit and the DAC happily handles 44/24 natively without re-sampling. There's absolutely zero error in this. You're also right that this would/should do the trick on the LG...

    LG V60 ThinQ smartphone

    I found this online: Sprint 2G/3G CDMA network shutdown date: April 1, 2022 (formerly January 1, 2022) Sprint 4G LTE network sunset date: June 30, 2022 T-Mobile 3G network shutdown date: April 1, 2022 (formerly October 1st, 2021) Looks like an LTE-connected V40 should be...

    LG V60 ThinQ smartphone

    Very surprised to hear that. What are the services t- mo are dropping on April 1st? Sounds like a bad April fool's joke. V60 or ROG Phone 5(s) are the best choices right now: https://www.hypethesonics.com/dapti-database/. Seems like the V60 is the only one that ticks all the boxes you want.

    Etymotic ER2SE - A Reference Headphone for your Ears and Your Couplers

    I'm not sure if anybody else replied to your post, so here's my $0.02's worth. I recommend learning from my own mistakes and not bothering. Even if you can finagle your 1/2" mic into your coupler, you're going to have to do an awful lot of work to calibrate its internal volume and transfer...

    LG V30

    We've tested a ton of devices single-ended vs balanced, and have never (even once) seen an improvement in SQ from the balanced output. You can check the numbers by going here: https://www.hypethesonics.com/dapti-database/ and selecting the 'All Variants' option. The only real use for a balanced...

    LG V60 ThinQ smartphone

    Can you go to UAPP's settings, then 'Internal HiRes audio', then 'HiRes driver audio format' and set it to 32 bit and see if that helps?

    Some thoughts on our inevitable dongly/post-LG-phone existence: https://www.hypethesonics.com/hiby-fc3-minihype I can't be sure what MQA is doing over a wireless connection. I doubt A&K will tell you. I'm pretty sure MQA/Meridian will not tell you. Also, I presume you mean AK Connect? If so...

    LG V30

    I want to first say a huge big thanks to @kkugel for the recommendation on the HiBy FC3. Secondly, I need to offer profuse apologies to @kkugel for my earlier cynicism, skepticism and dyslexia (I initially misread the FC3's specs - it uses a newer ES9281Pro DAC, not the ES9218Pro that's in the...

    Etymotic ER2SE - A Reference Headphone for your Ears and Your Couplers

    Sorry for the slow reply folks - too many things going on this week. Some bookkeeping issues: 1) I don't actually know who's up next. @McMadface had mentioned @crinacle and @oratory1990 were interested, but that was a while ago. I've not been in touch with either of those guys directly and I...

    Beyerdynamic Xelento!

    The main thing to be careful about with a replacement cable is the size of the mmcx plugs. For the Xelentos to sound their best, you want to get those resonance peaks as high as possible, which means deep insertion. You can only achieve that if you use eartips like the SpinFit Cp100 (or Cp145...

    Audio Measurements on a Headfi Budget

    I'll say yes only because I don't know of any other threads discussing reasonably-priced measurement hardware. (I'm not talking about DIY couplers that you can make out of vinyl tubing, etc. I know that's been discussed elsewhere, but a totally build-your-own coupler approach makes it...
