Coming from ie600 which is tuned magnificently to ie 900s these are a defo step up in the clarity of the highs with zero sibilance and brilliant craftsmanship.
Being a gear head the only way forward is little nuances with a huge price tag but hey it’s all for r&d so I’m game. Love the sennheiser tuning and can recommend them to lovers of any music genre.

Masterpiece In ear audiophile headphones
The IE 900 is one of the top choices for anyone serious about their audio experience. Its combination of superb sound quality, premium build, and provided accessories make it a worthy investment for audiophiles and music enthusiasts. I have it paired with a FIIO KA 3 USB DAC and it delivers one of the best sound stages, with clear separation of musical instruments. The ear tip fit plays a major role in determining how in ear headphones sound so playing around with several different kinds can make a difference too.. I played with the stock silicone, AZLA Sedna Earfits and several different types of silicone Spinfits before settling for the Spinfits CP 100s for bass and soundstage. In general the longer the eartip the deeper the bass and the wider the inner diameter of the eartip in relation to the nozzle/driver tip of the headphone the better the soundstage and clarity. Best to try several till you find one that works for you. Almost..yes almost ... as good as their HD 850s (which are my gold standard headphones) however thats kind of comparing apples to oranges. Sennheiser headphones tend to be neutral/warm so take some getting used to for folks new to the Sennheiser sound signature compared to say other families of headphones like B&W and B&O etc. The IE 600 (my previous purchase) comes close but the sound stage and instrument seperation on the IE 900 is clearly superior and the bass is richer and more textured. Overall very happy with my IE 900 purchase espescially with the price reduction on sale.

IE 900
This is my first-time experience. IE900 provides you every detail and crystal-clear sound, feels kind of fresh and new experience not like any other headphones. The best ever before.

Glorious sound
Long time, loyal Sennheiser customer. I own many different models of ie phones. The ie 900s are the epitome of fine listening. I currently am using them on everything from Pink Floyd to Mark Knofler to Doobie Brothers to U2, the Doors, and many more. My running experience is blissful when I pair the workout with good music heard through my Sennheiser ie 900s.
