Yes sound is lower, but even when i equalize both sounds from hyperx dongle and apple dongle, apple one is more muddy.
Im definetly aware of the danger going down dac/amp path, thats why wanted to try this cheap dongle first, i guess i will buy Akg K361 or something instead going to dac route.
It is USB-C to 3,5mm jack.

I guess this is not called lightning then, but it does have dac in it, thats what i read.
