Rated 5 out of 5 by from Well worth it This is what my son wanted as a graduation gift and what he wants he gets! Now he can play fortnite with an advantage over his friends! Best gift ever, his words exactly. You know my son is simple! You figure a college graduate would want a new car or a down payment on an apartment. But now I can keep my son around for much longer! But hey, at least when I give him rides to the store for energy drinks, he will ride with a smile!

Rated 5 out of 5 by from Love them I bought these a month ago and had to sell my Honda Civic but it was so worth it! I just listen to sounds of civics reving on YouTube and it sounds even better than real life!! My wife was mad at me because it was our only car but who cares for headphones like these! 10/10 would buy again.

Rated 3 out of 5 by from Volume control is not working The sound is great, however I cannot do the volume control with the remote. It should work perfect with iOS products, so I am still finding the solution.

Rated 2 out of 5 by from Pricey but not worth it. bought these for my child, he was not too impressed. He was mad at me because he wanted a new PS4, but i mean headphones have so much more versatility. He was also wanting the Nintendo switch, buttttttttttt, headphones right? Durability is great! he chucked them against the wall a few times but all working. ALSO, WHY IS THERE NO BLUETOOTH.

I may be purchasing a used k3003, it is not a k3003i. I have seen pictures it says made in Austria and has no controls on the cable. Is the a copy or did AKG make this and if so how long ago. Thanks

Does its remote and microphone works on AndroidOS, especially with Samsung Galaxy phones?

Asked by: Bekhruz
The microphone should work on Android and Samsung phones, however, you will not have the capability to control the volume because it is specifically designed for an IOS device.

Does this have active noise cancellation technology built in? I ride a Harley with a very loud exhaust, at 85 mph (yes legal), I cannot hear the wind noise (110db) over my exhaust. Will this significantly reduce the wind and pipe noise?

Asked by: NatalieEGH
It may be legal but it's incredibly risky for you as well as any passenger and anyone else on the road.
