Got these couple days ago. Very comfortable shape to use, great sound for the price, nice base without overpowering, very clear highs and mids. Not to mention it looks great in your ear without sticking out (using it wearing beanie hat ) Ive never used the previous version but Ultras never drop a connection, 5.0 has a great range, using it on Iphone X max. Maybe i got lucky for ordering silvers but thats what i got - silver ;-). Pretty much my daily drivers from delivery. Introduce them to a couple of my audiophile friends, they were blown away by the price and quality for TWSs.
Make sure to spend some time to pick best fitting tips. I used the once they included. They arrive with mediums like every other IEM but somehow they sounded flat and high pitched, as soon as i switched to a different size its a completely different experience. I cant find the foam tips for them but i dont feel like they need it.
P.S. Dakoni bulletz fit but they sounded horable with them. Could be my ear shape, but switched back.
