IE 900

I own ie300 and wanted to upgrade to the best Sennheiser can offer today. Well, I'm very impressed! Everything about the ie900 is amazing. Looking forward to get the custom comfort eartips in the US to reach the audio-nirvana :)

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.

Great IE900 sound.Great Sennheiser!!Great service!!!

One of the best single dynamic drivers in the market. I've been using a lot of other multi-driver unit including hybrid and BA and ES. IE900, after being an IE800s and IE800 user, has taught me again that the level of "completeness" and the "seamless" transition between highs and lows prooves the unshaken place of single dynamic driver IEM's. IE900 has again improved from the IE800s, bringing the lows even more accurate while increasing the clarity of the mids and highs again. Fantastic product.

Very detaieled natural sound in a different league to mass market ear buds
