Wow, what a difference getting a good fit makes! Full range of hard hitting bass and airy treble! It has all the detail and energy I've been looking for. Every octave sounds tight and responsive. Finally got these Noble X to fit right and they sound so good with live music. Eva Cassidy Live at Blues Alley is just fantastic! If you aren't happy at first with the sound, I think you really need to go through your drawer of old earphone tips...
