As I have many high end iems in my hands (and ears) right now, I thought I would give you an update on my impressions of the 5.0 vs. these iems.
The 5.0 (and I suppose all heir iems?), have a specific approach to sound (to my ears), which is "nice sounding" and "non fatiguing". They do not impose the music on you, just let you enjoy it. So it is more laid back and much less aggressive than iems like the Kaede or the 1plus2. Some people do not like it as they like music to be thrown in their faces, and sometimes I want that. But when I want things smoother and more chill, the 5.0, is great. It does not mean that the 5.0 is not dynamic, bass punch, speed and texture are very nice. There is just a little more more distance to the music that makes it more relaxed.
Maybe the 5.0 is not at the technical level of 1plus2 or Miracles (less good dynamics and punch than 1plus2, smaller soundstage than Miracles) but it is half the price and clearly not half the performance. It is actually quite close in performance so overall a very good deal IMO. When I listen to the 5.0, beside the specific sound presentation I mentionned earlier, I cannot find any fault to it.
I actually like the sound signature better than that of the 334 and the IE800. I am not saying it is better, but that I like it better (I say that before some ayatollas start yelling at me). The 334 has better and more engaging mids, and more bass punch, as well as "bigger" sound, but I am not such a fan of the bass, which could have been slightly tighter IMO. The 5.0 sounds more balanced accross frequencies IMO while remaining very fun. The IE800 has more bass punch than the 5.0 and maybe more clarity overall, but it is much too bassy IMO, so the 5.0 once again has a better balance overall, and is definitely much less fatiguing.
All things considered, I will be keeping this iem as my go to relaxed universal, with great ergonomics and sound, where I know I will never be disapointed.
