#15 SoftEars RSV: $729.00 Amazon eBay
Pros: A preference score of 76 in crinacle’s measurement shows a response that sits close to the Harman target, and it is rated above the FiiO FD5 and the HIFIMAN RE2000. Five balanced armature drivers with 8 ohms impedance and 125 dB sensitivity mean it runs easily from a phone or dongle. The wired design suits home or portable listening with a source of your choice.
Cons: It sits at a premium price for an in-ear, and a preference score of 76 is no higher than far cheaper wired sets achieve. The very low 8 ohm impedance can interact with sources that have a high output impedance, and 125 dB sensitivity can make hiss from noisy sources audible. It is wired only, with no built in microphone.
