Because of its fragility (is that the plastoc) and low extent of use this headset is not worth more than € 150 we read. This is the general max 70 euros.
I took this headphone for a closed headphone for recordings and listen to music like hip-hop and dance floor but certainly not for monitoring or mixing.

Price / quality ratio:
zero if Bought 150 euros
good if purchased 50 euros

I repeat that choice right from the conditions fixed in advance.

PS: given its fragility I think it's a bad idea to fold it constantly (although it is planned for). Opt for a small carry bag that does not require bending if you want to carry your DJ sessions and make it last a little.
