So, because I am obsessed, I purchased the following to compare to my sony xm4 tws:
1. Akg n400
2. Devialet Gemeni
3. M andD MW08
4. JVC 1000t something
5. Noble Audio Fokus Pro
For the sony's, I use the Azla Sedna tips and they work and fit great and have outstanding sound for a TWS. Lots of people make recs, and I never like them better than the Sony's. THis includes Sennheiser, B and O, B and W, and all the overhyped bull you can imagine. It all sucks. Enter here:
AKG: great bang for your buck. FOr $74, hard to pass on these. Use different tips though, which is true for basically all of them. These are less refined, but work well, and sound great on a budget, but not as good as the Sony Xm4's.
Gemeni: I actually like these. You may like them more or less than the Sonys, but sound is about the same quality with differences in tone. I like the fit, but they are less reliable, and the sound without ANC is just so-so. If I was going to keep a back up pair, they would be these. Well... sorta.
MW08: M and W falls into the above. Overhyped, and not good at all. I don't what alien ears these fit into, but they don't fit mine, and the disc part keeps them from going into my ears comfortably. Back to amazon
JVC: another one I don't get. Don't fit great, don't sound great. Just mediocre all the way through
Fokus Pro: Boom! This is how you do it. Keeping these, and returning the other 4. Fit is great. They sound amazing, and even the tips out of the box sound good with them. The app work, they look beautiful. This is a home run. Some people have drop issues, but none for me so far. This is the very clear winner. It's not even close to the others. It's not a huge improvement over the Sonys, and I have not used them at the gym yet, but they have more separation and a tad bit better resolution and they just work and fit and sound great. Great job #nobleaudio!
