Very nice! Can you do the foam inserts with the Harman target? I think it will measure quite flat in the upper frequencies.
ReplyDeleteSorry for the late reply. Foam couldn't reduce the peaks in upper frequencies.
DeleteSome new Bluetooth IEMs come with a DSP built in. For example, the Jaybird X3 and Freedom F5 have a 5-band parametric equalizer that works, regardless of the device they are paired with. Do you have any plan to review any models from this class of IEMs? I'm curious to know how you would tweak the built-in DSP for the measurements to match the diffuse field, Harman, or any other target. Or how these sorts of devices would sound after you do so.
ReplyDeleteI'll gonna upload few Bluetooth IEMs; MobiFren GBH-S840 and GBH-S860 and Iriver IBE-W1. MobiFren's IEMs have DSP as well.
