Let me start by being up front. I'm a Sennheiser fan boy. Always have been. I've owned every Sennheiser IEM from the CX150 through the CX215 and CX300 II all the way up to the 880, IE80, and finally the IE40 Pro and IE800. I also own the HD599 and owned the HD600, 58x, and HD280 PRO, so I know my Sennheiser sound. With a few hours into these newest IEM's, the IE300, I can emphatically say they are the best Sennheiser IEM's they've ever produced.

Yes, even better than the IE800, which remains their flagship earphone. Apparently, Senn took the 7mm XWB found in the IE800 and IE40, and refined it? From the sound of it, YES THEY DID. These are a very refined listen. They remind me of the sound coming from my HD599 cans more than they remind me of any previous Senn earphone. They have much more controlled highs than the IE40, and are as refined as the IE800 highs. Where they separate from the IE800, aside from crushing it in in fit and comfort, is the pinpoint imaging. The soundstage is as wide, but the imaging is world class. Better than just about any IEM i've ever heard, and i've heard over 100 from $5.00 to $1,000.

With great air and instrument separation, the placement of instruments in their place is just a revelation. What a treat! Mids are balanced, but not forward. These are mildly V shaped, with present bass that's never bleeding into the mids, but that have weight, impact, presence, and moderate speed. As I mentioned, there's have a very 3D presentation, with plenty of depth and height. These are very refined and mature sounding. The Sennheiser veil isn't very present here at all, certainly not like the IE800. The mids are more forward than the IE800, and the bass a touch less. Above average air and instrument separation. Timbre is also above average, but not what i'd call world class, but that's because the treble, though very refined and present, isn't overly extended, and there's no peaks, that would give the illusion of overly transparent highs or weighty timbre. It's just right.

Extension is excellent and so is timbre, and realistic (don't listen to those who said the timbre isn't realistic..they are WRONG). It's just not overdone and very tasteful. The cable is so much better than anything else offered by Sennheiser. Why oh why did Sennheiser not use this cable on the IE800?! or even the IE40 pro or it's siblings? If they had, they might have had an earphone as popular as the CX300, which put Sennheiser on the IEM map in the early 2000's. Comfort is supreme. The components are attractive, well built, and smallish. I'm really impressed with the build quality here. The sound is fun, coherent, clear, refined (have I mentioned that yet? lol), with strong bass response. Ok, time to go listen to more 80's music with these! Later!
