Звучит очень ярко, и сочно.Не понравилось как звучит металл.При регуляторе громкости на 9 часов уже громко.Современная музыка и электронная звучат изумительно.Слушаю на акустике Dali.мне кажется акустика 8 ом чуствительность до 90 была бы больше в балансе.

Sound is fabulous.
I never expected such transparency and spacious soundstage from an IEM.
Simply the best "portable" headphones. Pity it was discontinued.
