Sennheiser CX 300S In Ear Headphone with One-Button Smart Remote - Black

hello i will make a review of two of sennheiser's in-ear headphones it's the momentum in-air and the cx300 as reference sound i've used leonard cohen's song darkness which i think has an interesting mix and i also used his song nevermind usually i use leonard cohen's latest recordings as reference when it comes to earphones headphones loudspeakers i also used the han simmers song time and i used a recording of gustav mahler's second symphony from deutsche gamophone i think they have several recordings but usually i trust deutsche gamophone for sound quality and the symphony number two by gusta mater is also very dynamic and that makes them makes it good for reference i also use some metal progressive metal by evergrey they're a song from their latest album called where august where august mourns so i will tell you a little bit about each of the headphones when it comes to the momentum i
