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 say they are the best Sennheiser IEM's they've ever produced, but with a caveat. 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 V shaped sound signature, with very present bass that's never bleeding into the mids, but that have weight, impact, presence, and moderate speed. That's the caveat. THESE ARE BASSY. These are without a doubt a bassheads dream earphone. Though there's no bass bleed, the mid bass is very present and the sub bass digs deep. Where these fail me as a be-all end all is that the bass speed is only moderate. They aren't the most resolving bass as far as speed and resolution, so they can lag just a tad with the fastest of tracks. So this is the caveat that, though technically make these a superior Senn, also makes me reach for the Sennheiser IE100 more often. The ever present bass. 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 more prominent. 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, bassy, coherent, clear, refined (have I mentioned that yet? lol), with strong bass response (mention that too?!) . Ok, time to go listen to more 80's music with these! Later!

The heartbeat of the IE 300 is a refined version of our Extra Wide Band (XWB) 7mm driver, made in Germany and revered for its breathtaking acoustic performance in a deceivingly compact package. A new blend of materials in the diaphragm provides high frequency clarity, subtly warm mids, and clean bass response with low harmonic distortion.

Headphone Profile
In-Ear
Sits comfortably in your ear canal to deliver a private listening experience in a compact size.
Sealed Fit
Includes an ear adapter kit for a comfortable fit that maximizes bass response while blocking noise.
Wired
Comes with a detachable cable for connecting to singled ended 1/8-inch (3.5mm) outputs such as digital audio players, DAC-amps, headphone amplifiers, mobile phones, laptops and more.
Air Traffic Control
A key element of the IE 300’s balanced acoustical performance is the back volume—a miniature room-within-a-room that helps manage the flow of air. The direction and overall volume of air is controlled with precision as it travels through and exits the acoustical system. Further, a frequency absorbing resonator chamber was applied to overcome masking effects that regularly occur in the ear canal, unearthing nuanced audio details previously buried in the source signal.
It’s All About Connection
Sennheiser’s engineers were tasked with delivering peerless sound AND dependability.
They started with ultra-durable gold-plated Fidelity+ MMCX cable connectors and seated each within a recessed, 4.8mm-wide socket for outstanding strain relief. The para-aramid reinforced cable is rated for thousands of bend cycles, adding exceptional durability to the overall listening experience. Included are (3) sizes of silicone ear tips and (3) sizes of memory foam ear tips to conform to the unique shape of your ear canal, maximizing noise isolation.

Engaging, warm, and comfortable IEMs. Good value for $200
These are really comfortable as they are small. (although I went with final audio tips as they gave me a better seal and less so with its stock tips). The wires that goes around the ear has memory in it. I like it, some may not. These have a bit of a V shaped sound, with increased bass and treble. It has increased bass but not overbearing. Has nice impact making music more engaging. Bass is not muddy or sloppy it is well done for my taste. The mids are recessed a bit but it does not bother me as I'm a vocal lover. The overall sound signature is warm and non-fatiguing. It comes with a nice pocket sized case with 3 sets of silicone tips and 3 sets of foam. I much prefer silicone as foam tips irritate my ear holes after a while. I could get good sound from the stock silicone tips but when yawned, moved my head or jaw the seal would sometimes break and the bass completely falls off. I'm happy with these for the sale price of $200. I think they beat my ikko oh01s and complement my Blessing 2s when I want something more fun and need to wear for long periods of time.
