Rated 1 out of 5 by Rafal from Terrible design! Absolute disaster headphones! It's an absolute waste of money. The plastic hinge or so called 'Unique 3D axis 2 folding mechanism'' is so badly designed it breaks after very short time making the headphones completely useless. The 1st pair broke on both sides after maybe a month of use, only in the office. They were replaced by the shop. With the 2nd pair I was ultra careful, so they've lasted a bit longer, unfortunately long enough to go over the guarantee time. What a rubbish!

Rated 1 out of 5 by David from Horrible design! Sound quality is OK but design and customer service is very poor! The hinge connecting the earpiece to the headband is so weak that BOTH sides broke after minimal use. I used crazy glue to re-attach the first break and was careful to use lots of caution. Then the other side broke at the same attachment point. I called customer service and was told I have NO recompense since they were outside of warranty period. It looks like subsequent designs are poor as well. I would stay away from these!

Will a 2.5mm 3 connector (stereo) plug work in the K490NC or do you need a 2.5mm 4 connector plug for the headphones?
You only need a 2.5mm (4 conductor) to 3.5mm audio jack for you to use the AKG K490NC.

How do I connect my headphones to my phone
The K490NC comes with a 2.5mm – 3.5mm audio cable where the 3.5mm end plugs in to your phone’s headphone jack.
