Mifo o7 in da house! Before I forget, just wanted to say that they measure the same for tips as the 1Tx: 5mm at the max, 4mm inner ring.
I'm listening with the out of the box silicone tips and will test with the others mentioned earlier tomorrow when I get them. (1-day shipping, thank you Amazon!)
I need to A/B test this, but here's my first impression...
By comparison, these feel like they aren't even in my ears. Very lightweight, and somehow stable, even without wings. For a while I was shaking my head around trying to see if I could dislodge them, because it just seemed weird that they were as stable as they were while feeling like they were just sitting there chilling, weightless. With the 1Tx, I couldn't even attempt to eat or chew gum with them (which is why I also want to try other tips with them), but I get very minimal feedback when I open my mouth, move my jaw, etc. Another thing I just tested was walking. Again, the 1Tx created a not-so-nice THUMP with every step. Listening to music at a normal volume, I heard nothing when I walked. I then turned it down well below what I'd normally listen at, and still heard no thump or feedback. Even when i take a deep breath, I'm not getting any noticeable feedback.
Listening to music, I'd put these in a studio monitor category. If I summed it up so far, I'd say Clarity & Balance.
I'm not feeling as though anything is muted, nor is any range out of balance or bleeding into another range that it isn't supposed to. That said, the bass is reserved and tight. This is the kind of sound I like, I don't like boomy bass unless the song demands it...and if the song demands it, the bass responds accordingly. Just to test that theory, I am listening to "A Final Hit" from Leftfield. This has some low frequencies that just rumble in the background. I don't feel like the bass is hiding from this song, but it isn't thumping either. If I was able to tune this a bit, I might bump the bass just a TAD, but then again don't really feel like it's needed and I feel as though I'm listening to the songs as they were recorded, if you know what I mean.
Jumping over to assess the highs...Listening to Flyleaf's Thread now...their lead singer has some exceptional heights and the guitar and cymbals are up there to match her. I feel like this might be a tad hot. If burn-in is a thing, I suspect these might need some time with some pink noise. That isn't to say they aren't good to listen to now, just pondering how these may improve.
I was pondering what song might test the ranges, and reminded myself of a song from Grimes called "Dream Fortress". It is pushing the limits of highs and lows, and feels like another good song to test with. Again, I'm feeling as though these are balanced across the spectrum. Pretty impressive.
Jumping over to some Florence + the Machine to evaluate the sound stage a bit. I think I could get lost in the sound...I've loving it.
Ok, I analyzed it a lot more than I intended straight out of the box, but the more I listened the more I already love them. I'm going to go workout now and see how well they stay in place during that kind of activity. Given their IP67 rating, I'm excited to see how well they hold in place since they are not going to have an issue with water/sweat.
BTW...The case is insanely small and VERY well made. Quality.
PS: The 1Tx will be returned after I test them with the tips I ordered...They will never sound this good. I didn't think this sound was possible in a TWS.
