Received my pair today. Bought from the Shenzhen Audio amazon option. Only took a few days in Australia, not bad.
For $72AUD they are impressive. These are my first set of IEM's and I am finding them fairly uncomfortable and cant use for extended periods, even with the smallest tips (ones at the top right of the card). Are the SpinFit ones slimmer? I must have narrow ear canals.
As for the sound, they sound pretty good for the money. I have tried with my iPhone 11 Pro Max via the apple lightning to 3.5mm adapter and also on my Benchmark HPA4/DAC3 combo. They don't really compete with my HD800S in terms of overall clarity. With acoustic music, they seem to be a bit dull. I tried Maiky76's eq but I didn't really like that tune. The bass kicks ass though. Kick drums etc are great!
For anyone playing along at home, subjectively speaking, have a listen to the following album on Tidal. It's a really well recorded acoustic album, which I love, by Tony Rice and David Grisman. I've listened to it on a lot of setups including Salon2's and Studio2's. On those speakers and the HD800S (with Oratory EQ) there is a crisp metalic sound that is true to the mandolin and Tony's guitar strings that is lost on these IEM's. I think it might be able to be EQ'd a little better to get them there. Thoughts? Subjective I know, but its just something that ive listened to a lot on various well measured speakers.
