Got one of these for office meetings over MS Teams. I hate the Jabra over-the-ear USB headset provided by my company.
Sound quality seems decent but I don't really use these for music listening as my new phone has a USB C port only.
Build quality is decent but the braiding doesn't cover the entire cable.It only goes upto the part where the R and L wire split off.
One minute attention to detail I really liked on this kit is that the right earphone is concave (The part which has a carbon fibre like weave in the photo)
and the left is convex. Really easy to tell the R and L earpieces apart just by touch without looking at them.
My only concern would be longevity as I am pretty rough on these IEMs.
