FLUX IN-EAR PRO - Headset ( In-Ear Ohrhörer )

Hello I have these headphones I use them for frequent telephone and on the road I like them very much They sit comfortably, have good sound insulation, good equipment several interchangeable nozzles, case, adapter two Jack 3.5 mm The sound I liked, but as for me there's too much treble, and bass is virtually nonexistent In General, can rate 7/10 (despite their price)
