S10+ here. The phone still runs apps smoothly and the camera is good enough for my use.

Can agree with using for a week. When I first played a song with olina se I got disappointed but decided to think not too much and use it. Keep in mind my iem before is warm and olina se is bright-ish tuning.

Tomorrow I noticed the bass have impact that is lacking in CCA FLA(I have to downgrade from hiby loki since the cable broke). The treble despite being peaky never felt harsh(it was 12k peak). Midrange is mixed opinion as some songs vocals sounds absolutely dead which is most likely bad mixing as some songs vocal are just wonderful especially asmr where binaural mic are used.

Most of the songs I listen are from rhythm game(osu) so I mostly listen while playing. I found music itself to be a bit boring so I enjoy having some notes to tap along the rhythm.
