Sony XBA-30

Disclaimer: This pair is owned by Flysweep, who generously let me borrow his IEM for a full month. I truly appreciate your contribution, my friend.

Sony XBA-30 is a revised version of XBA-3. As there isn't much to complain about XBA-3's original performance, the question is: What has been actually "revised" from its predecessor?

PRO: Now the cable is coated with silver, the overall impedance is just slightly lower. The sub-bass decays slightly longer than XBA-3 too.

CON: THD is actually worse, reaching 1% @ 1 kHz : 100 dB SPL, along with the misaligned channel matching.

ON SECOND THOUGHT #1: All the other factors are totally identical to those of Sony XBA-3. Please refer to XBA-3 for further details on modification / effort for improvement.

ON SECOND THOUGHT #2: Above data can be interpreted that XBA-30 is more tightly controlled, but the difference above is actually smaller than that of between MH1 and MH1C.


  1. The cable is coated with silver? Who said that? You don't care for exotic cable techniques, fine, but get your facts straight.

    The Furukawa PCOCC-A process does not utilize any silver-plating. It is their current "alpha-OCC" that has silver-plating, and currently only Furukawa's affliated Furutech and ADL are able to use it.

    The PCOCC-A process is no longer available. It too uses the general OCC production process, but anneals the wire for increased conductivity.

    Sony took advantage of the last batches to be made, along with companies like Oyaide, Acoustic Revive, and others.

    1. Yup, somehow I assumed Sony used the current model LOL I knew something was wrong for sure though.. Thnx for the heads up!

  2. Hello, which tips would you recommend for XBA-30? I find no difference between XBA-30 and XBA-3; The treble is very harsh for my ears.
