    Reply to review by 'yuriv' on item 'Sony MH755'

    Hi @brianforever. I just saw this. I haven't posted in nearly two years, basically putting the hobby on pause since the pandemic began. The world has changed. When I wrote that report back in 2018, I saw no reason to conclude that the MH750 and MH755 had different drivers. They looked the same...

    Reply to review by 'yuriv' on item 'Apple USB-C to 3.5 mm Headphone Jack Adapter'

    Yes, you can see the adapter in the photo above. It works on both Macs and Windows PCs. I haven't tried it on a Chromebook yet. I also tried an OTG micro USB adapter on my Android devices, and that worked too, but the maximum volume was around -20 dB lower than what's possible on other OSs. It's...

    Relatively cheap headphone measuring kit?

    I should check out these forums more often. My last post before this one was way back in November, well before the lockdowns. The world has changed, and I've put aside all of these fun audio projects for now. I've been happily listening to music or making music with the cheap or mainstream gear...

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

    First of all, thanks for sharing the files for the Harman 2018 and 2019 IE targets. I’m not exactly sure which experiment you’re referring to. My post is only about the new target curves and the SoundCheck software. Their measurement routine uses two couplers so they can measure both channels...

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

    Zero arguments, because you took off the devil's advocate hat too soon. Lol. I suppose it's better than trolling, or if you prefer, playing the role of provocateur. I'm just about ready to send the package to Europe after finally giving up on figuring out how to measure impedance vs. frequency...

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

    It doesn’t seem much of a chore if it’s the background task. Push the IEM a little farther in, then take another measurement while you’re being productive with something else. Little and often gets the job done too. Believe me, I’m just as lazy as anyone here. Showing the effect of the...

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

    Here’s what I have so far. I measured with my portable rig with the Apple USB-C dongle instead of a “proper” interface like the Focusrite Forte I have parked at my desk. The results were close enough when I set the mic’s level in Windows to 60 or higher. It’s a bit strange; with the level any...

    Reply to review by 'yuriv' on item 'Samsung AKG OEM In Ear Headphones'

    @SilverEars Oluv offered to send me one of these a while ago. Then you put it in the ER2SE tour. I figure it's cheap enough to get my own samples for modding. I wonder where you're hearing the canal resonance. For me it's at 6.3 kHz and no higher, which is not ideal. Best is 8 kHz because the...

    Reply to review by 'yuriv' on item 'Samsung AKG OEM In Ear Headphones'

    @SweetEars I just tried it with different kinds of wide-bore tips. I posted my findings inside a spoiler at the bottom of the review. I didn't notice a significant difference from stock tips. This IEM is sensitive to insertion depth. If you're getting much different sound, could it be that your...

    Sony budget earphone discussion thread (MH750, MH755, MH1C, EX300, etc)

    I don’t see much online about the Sony MH410c earbud, so I suppose this is as good a place as any for this post. Tyll Hertsens wrote back in 2011 that “pretty much all earbuds suck.” As a group, they consistently have the most anemic bass and the worst distortion. Measurements of earbuds back...

    Review by 'yuriv' on item 'Samsung AKG OEM In Ear Headphones'

    This isn't really a formal review. It's just a fitting place to post my experience with the product so that I can link to it in forum discussions without having to retype the same comments over again. I suppose it kinda sorta works as a review. It used to be $99? The EO-IG955 is the earphone...

    Sound Science Approach to Modding Headphones

    I think my other coupler is the same model as your TBC1-4. It even follows the slight roll-off in the bass. The response is really not that different from the one I usually use, which is on a plinth. Blue: difference in response (+70 dB) The biggest difference does seem to be near 1 kHz...

    Sound Science Approach to Modding Headphones

    Judging from those measurements, it looks like your samples aren't close to target at all. It's a different result from what everyone else is getting, but you have to report your data accurately. It also looks like you’re inserting the tip really deep into the coupler. Sead Smailagic, the...

    Sony budget earphone discussion thread (MH750, MH755, MH1C, EX300, etc)

    I finally managed to continue what I said I would do at the bottom of that post you’re talking about. I wrote a follow-up here: link (scroll down a little) I just started playing with the idea again, but so far the results sound promising (to me at least): I’m really more interested in the...
