I find the Tin Hifi T4 a competent and good IEM, and I’m actually very happy with adding it to my collection. It’s the right type of sound signature for what I enjoy and I’m happy to recommend it at the introductory price, and even a strong consideration at the regular retail price.
I may come across slightly negative in this review of the KXXS, but that’s really when I am comparing it to the Kanas Pro, which is one of my most favorite In-Ears. It’s such a great IEM for the price – in terms of sound profile, build, comfort, and design that I find it hard to beat.
What really gets my attention about this product isn’t the assumption they use 10 grammy awards producer to tune the 2PRO but the fact its one of the few hybrid TWS iem, not just that but the fact that they use high-quality Knowles balanced armature as well as promising coaxial dynamic drivers
