The new packaging is much better and actually fits the contents. If you order the original you know what I mean by that. The sound is fantastic. It competes with much more expensive IEMs and I am highly confident in that statement. I tested it against Mangrid Tea, Fearless S8Z, Blon03, Shozy B2, and others. I did have an issue of the left channel cutting out. I swapped cables but still had the issue. The right MMCX connector snaps in “crisply” but the left one “mushes” in. So I believe that in manufacturing they are damaging the left connector somehow. I would contact before you buy and ask that they (Linsoul) tests before they ship to you.
