Oh.. Opera S wireless series..

I think you can think of it as a "cheaper" alternative for wireless iems =/

I tried it once or twice at Jaben Network, Singapore.
In terms of value, sa6 wins by a much margin.
As you can see, their opera iems only operates in wireless mode, and their method of insertion is by the top only, and i dislike their coiling wires =/
Those factors already made me look away from them, much less comparing about sound quality lol..

If you wear it downwards, huge microphonics as there is too much slack at the wires.
Whereas for the W-1 receiver, which you can adjust the cable length to fit your head to reduce the slack of the cables, the microphonics and the "sway" of the receiver.

To be honest here:
If you want to go wireless, sleek is the way to go.
Unless you want to take the sennheiser mx-w1 + custom earmould, and i heard that the isolation doesn't improve to be like a "real custom", only the fit improves much i guess.
And sleek audio is the only one with wireless customs.
But i like sa6's sound signature anyway, so not much problem for me.
