āThere are plenty of products in this genre ā size, shape, price all quite similar. Sudkeeās tech is different as Iām toldā
Mark,
Iām sure as each of aforementioned brands / products claims to lower noise and improve our listening experience to a certain degree. There is a market for ātweaksā like Puron, Akiko, eau2, Qk1, ipurifier and NCF so why not. Let the end users decided what they like and prefers in their unique audio systems.
IME, they are temporary solutions to bigger problem elsewhere and tweaks like these serves as band-aids until something else comes along.
