Coming from a Sony xb signature sound previously, I was confused between Sony Xb wired series or these new underdog Opera Factory Os1 Pro. Pritam from audio store suggested these, which made my purchase decision clear.
Design & cable- looks sick and copper wire is durable for long run I think so.
Experience with this babies- Mmmmaaan I was blown away with that bass frequency response, hitting every drops and beats right and hard, mid & highs is 5 on Five. All I know is I am treating my ears with delight wearing Os1 Pro. Only store where you could find these here in India.
Thanks Audio store.
