The earphone is very midrange and treble-heavy. Bass go but under very. The comfort, however, is very good and you can 'quietly' hear the phone in the background. The model is out of date (2015). Unfortunately there is no good open earphones longer on the market. For me unfathomable reasons, the production of good-sounding earphones OPEN has been set for more than 10 years. What shoud that? Each earphone manufacturers currently focuses solely on closed earphones that mean in my ears an absolute no-go. These closed earbuds you no longer hear the ambient noise - neither quiet home phone still traffic while jogging. What shoud that? Sony had released 20 years ago so good open earphones - with the label '... 975B'. Later, about 10 years ago, Sony had something cheaper and only sound slightly inferior model 'Sony MDR-E 931 LP / S earphones' released. And now there's this beauty and not to buy. Why, I wonder ?! Want because everyone who wants to listen to good music sound quality outdoors, waive any phone calls or even vital traffic information ?! We would like for all acoustically insulate public? Not me !!! ;)
