I´d been reading your Custom In-ear Monitor Buyer’s Guide because I´m looking for a CIEM with good quantity and quality bass extension. Here, your recommendation is Audio Earz aud-5X, and I´d like to know about this CIEM vs 1964 V3/Qi. What do you think is better option?
Also there many others like Lears LE-3B. What do you think has more detail with strong bass response?
Thanks again for this amazing thread.
If you budget allows, you might want to check V8 from 1964 ears.
