Worked perfectly so I could work perfectly.
Pretty simple and straight forward cable that works. I am using this in a home office to facilitate a multi-monitor setup. The cable is well made and everything fit as expected.

Bom headset
O fone é fácil de usar e possui um excelente som. Único problema está no microfone, não pela qualidade mas pelo fato de não possuir um botão para desligar.

Pretty darn good
Great solid headphones! The sound quality is pretty good, but on very bass heavy songs at a higher volume the drivers tend to become scratchy.Also, not great for big heads! Mine are at the largest possible size increment and my ears still get cramped after a few hours.All in all though, I do not regret my purchase. Phenomenal battery life and pretty nice sound quality for its price range!

Q
I'm looking for a good adapter to use my nikon lenses on my panasonic lumix dc-g9. vs
A
I can only speak for my Nikon 50mm f1.8 Ai-s manual focus lens and the Olympus Pen-E PL7. The K&F Concept® Nikon - M4/3 lens mount adapter ring for Nikon AI lens is well suited for this. The adapter sits firmly and without play on the lens and can be easily attached to the m4/3 bayonet. 
Q
Does it also fit on the Panasonic Lumix g70 ( Mtf )
A
No, the adapter is for CANON EOS EF to CANON EOS-M lenses. The bayonet for EF-M and MFT is different. In addition, the EOS M cameras have a back focus of 18mm and MFT a back focus of 19.25mm. However, there is a Viltrox adapter from EOS-M to MFT with the correct lens distance 
Q
I do not see if this adapter or any other model will match panasonic lumix dmc-g85 with nikon af-s dx nikkor 55-300mm? please confirm?
A
This adapter fits the Panasonic G85 perfectly. If your lens is a Nikon G lens, then you should have no problems. The version of this adapter I have is M43 (Micro 4/3rd) to M42 lens. Hope this helps. 
Q
Will this fit on a lumix lens to eos camera?
A
NO. 
Q
Will this work for a panasonic lumix g7?
A
hello panasonic lumix g7 is m3/4 mount, so the adapter ring could not work for panasonic lumix g7
