    Earbuds Round-Up

    To me, the biggest drawback with the A-3 is the lack of support from Earin. They offer gorgious hardware, but their software is buggy and customer service is very poor. I demonstrated to them with my ear simulator that max volume on the A-3 is too low with some rather quiet classical...

    Earbuds Round-Up

    Here are DF-compensated measurements of Rose Maria II, with different levels of seal on my miniDSP Ears coupler. Take them with a grain of salt, because the coupler's artificial ear is only a crude replica of a human ear. I pretty much agree with @ClieOS on sound signature and stage. It's...

    JVC HA-FW01 - The New Top End Wood Driver IEM (2017)

    I'm afraid you're asking the wrong person in that regard. I prefer a more neutral bass and have modded each and every JVC woodie to attenuate the low range.

    Drop + JVC HA-FDX1 Dual Carbon IEM...available in the US!

    It's stock with the mid-level (reference) filter. I don't have measurements of a micropore modded one. My guess is they'd be pretty similar.

    Unique Melody 3D Terminator 3DT Announcement Thread

    Measurements with 3M micropore tape strips of different widths: (DF compensated; red = UM 3DT stock, yellow = 50% nozzle coverage, blue = 80% nozzle coverage, green = 90% nozzle coverage, gray = JVC FDX1 w. ref. filter) Blue (80% nozzle coverage) is my favorite tuning. Note that even though...

    Official JVC HA-FW1500

    It's the same, FW1800 ist the international version and FW1500 the domestic (Japanese) version. Drop (former Massdrop) did not make any changes to the FW1800.

    Europe Deals Thread

    Both scenarios are possible, the one you describe *and* the one I mentioned. In case of the Fidelio X2HR, it was a Spain only offer. And in that case, if you're logged in from a foreign country, you may only see the offers available for shipment to your foreign address. It's easy to check which...

    Single & Multi Dynamic Driver Only IEM Discussion Thread

    JVC FW1500/1800 vs. FDX1. I loved the driver (same as the FW10000), but not the stock tuning. Did a (reversible) mod to make them more neutral and preferred the result over the FDX1. However, Drop doesn't seem to have plans for a custom tuned FW180X, so this one would be for DIYers only...

    iBasso IT00 and AM05 Two very different IEMs with one purpose, to Enjoy the Music!

    The screw-on mesh serves no acoustic purpose, so there's no point in widening it. The main reason why the IT00 lacks treble for you is probably its boosted low range below 500Hz, which masks the highs a bit. If you lower that range below 500Hz, the IT00 should give you perfectly good treble...

    Toranku's Thoughts and Reviews (and target EQ filters!)

    Don't worry, I was a bit dumbfounded, but didn't take it all that seriously anyway. As I said, your posts are generally well-informed and valuable, so let's move on. :)

    Toranku's Thoughts and Reviews (and target EQ filters!)

    In a way, yes! But I think it's a little more sophisticated than that. Think about how we learn to experience live music, it's pretty much always in an environment that adds reverb of some sort. Virtually no one learns what "natural" is, by listening to live music in an anechoic chamber. So...

    iBasso IT00 and AM05 Two very different IEMs with one purpose, to Enjoy the Music!

    I tried a few things to lower that mids warmth a little, but couldn't find a reversible and reliable solution. So, finally I ran out of patience and pierced the front vent, lol. Well, that's definitely a viable solution, but since it's non-reversible, I recommend to proceed with caution! Oh...

    iBasso IT00 and AM05 Two very different IEMs with one purpose, to Enjoy the Music!

    So I tried to replicate your mod (dried alcohol swab damper inside nozzle + rear vent tape / pinhole) and this is the measured result: (DF-compensated; blue = IT00 stock, green = IT00 tgx78 mod) The rear vent tape flattens sub-bass, and the front damper evens out treble a bit. Overall a...

    Drop + JVC HA-FDX1 Dual Carbon IEM...available in the US!

    Sorry to read about your issues with the FDX1. Just want to share my own FR and THD comparison with the Dunu Luna, since I know that you also have measurements of the latter. Note that I don't trust my THD measurements either, so please ignore the absolute values. But I think for a comparison to...

    DUNU LUNA - Impressions and Discussion

    No, it doesn't blow the FDX1 away imo, but the Luna is slightly better in several aspects. Imagine two pictures of the same scene, out of which one looks slightly clearer, more colorful, more contrasty and more three-dimensional than the other. The difference in individual aspects is actually...

    DUNU LUNA - Impressions and Discussion

    I agree with your review, the Luna is an impressively capable IEM and pretty close to my idea of perfection. Actually, the only one thing that kept bothering me during my evaluation was that slight upper mids glare. I listen to a lot of classical music, and orchestral pieces tend to have plenty...

    DUNU LUNA - Impressions and Discussion

    Looks fine to me, quite similar to my Sony EX1000 from sub-bass up to midrange. EX1000 is still a big personal fave when it comes to quality DD bass. :)
