#39 iBasso IT04: $499.00 Amazon eBay
Pros: A preference score of 69 in crinacle’s measurement puts the IT04 in solid, listenable territory for an in-ear. The 110 dB sensitivity means it is easy to drive from a phone or dongle without a dedicated amp. At 13 g with a hybrid of one 10mm dynamic driver and three balanced armatures, it is light and uses a driver mix aimed at bass weight plus detail.
Cons: A score of 69 trails the best in-ears, so the tuning is noticeably off the Harman target in places. The FiiO FD5 has a higher rating at a similar price, which makes it the safer pick if the Harman fit matters most. It is wired only, with no wireless option.
