Sennheiser IE 300 2

The Sennheiser IE 300 IEMS are wired earphones. No Bluetooth. No uncertain radio communications potentially degrading the signal. Just real wire. The wire is 1.25 meters long and terminated, of course, in a 3.5mm stereo plug.

IE 300 E

The IE 300 being a cabled set of headphones allows for incredibly compact driver housings that sit flush with the ear when worn – a far cry from the battery-toting true wireless in-ears that are dominating the market.

They actually look really nice. Design-wise the IE 300 is a hit. They are small, nicely rounded, and very small.
The right earpiece has a red ring, and the left one a black ring. Connecting and disconnecting the cables is easy and you get a nice click feel and sound doing so.
Design-wise there are 3 highlights. First, the tiny Sennheiser logo on the outside/faceplate. Second, the slightly tilted nozzle, supplying a perfect fit, and lastly the grill design at the end of the nozzle which is repeated in n-both the provided silicone and foam tips. It’s all in the little details.

Packaging and Accessories

The IE300’s blue and gray packaging matches that of other headphones in Sennheiser’s audiophile series of products.

Inside the box, you’ll find the IE300 alongside a sweet array of accessories. Included with the IE300 are 6 different sets of ear tips; three small, medium, large silicone tips, and three small, medium, large memory foam tips. The stock cable is using MMCX connectors on the headphone side, an angled 3.5mm jack on the source end, and it measures roughly 1.2m, which I find to be a very comfortable length for most use cases. Additionally, the IE300 includes a very nice, portable hardshell case; it’s low profile and easy-to-pocket, but it still has plenty of room to house the IEMs as well as the included ear tips and cleaning tool.

Audio performance

Review the Sennheiser earbuds IE 300

Once a successful seal was made, the IE 300 offered a truly rich and spacious musical experience. One notable feature of these particular in-ear buds is their ability to create an excellent sense of space in their reproduction of music – a characteristic that’s very rarely found within the category.

Quite often, the inherently limited design of in-ear devices means that the listener ends up with somewhat compressed audio (albeit with some clever tricks to mask this, in some cases) due in part to the smaller drivers.

The IE 300 uses 7mm Extra Wide Band (XWB) transducers in combination with extra air chambers to provide clarity in the audio reproduction and offer that aforementioned sense of space. Precision engineering pays off.

In use

The IE300’s build is a slight departure from that of other headphones in Sennheiser’s audiophile-oriented IEM line-up, instead of more closely resembling the design of the headphones that comprise their Pro series. As a result of their Pro-audio-inspired design, the IE300’s chassis is very small and lightweight, which makes for an IEM that is durable, lightweight, and easily portable.

Fitting the IE 300 over and around your ears is incredibly easy, thanks to the swiveling connection that the buds have to the cabling along with the malleable ear hooks. We even found these hooks thin enough to coexist rather politely with the arms of eyeglasses, for those that wear them.
The memory foam tips are outstanding. They conform very nicely to the user’s ear canal, which I found made for significantly more comfortable listening sessions, they greatly enhanced the passive noise attenuation of the IEMs, and I felt as though I got the most sound out of them since the seal was just right.

The bass region on the IE300 has a pretty significant up-shelf under 200hz. This emphasized mid to sub-bass region makes for a very warm-sounding bass response, which for my tastes and preferences made the bass come through as a little bit swollen at times.

Nonetheless, the bass here to be very enjoyable. it no was overbearing or intrusive of other frequency ranges, and the roundness and fullness that the bass here provided to instruments’ lower registers.

Build Quality & Cable

The build quality is excellent and with the soft, round edges the IE 300 looks comfy, high end and professional. The Sennheiser IE 300 has a very plastic look at feel, but it’s actually very well built.
The IE 300 cable according to Sennheiser is para-aramid reinforced and terminated with gold-plated Fidelity+ MMCX connectors, which are recessed with a 4.8mm-wide socket. We all know that MMCX is very durable, so that’s always good. On the other end of the cable, you’ll find a 3.5mm plug.
Because of the special MMCX version you might have issues hooking up your aftermarket cable to the IE 300. A balanced 2.5mm and 4.4mm terminated cable will be available (sold separately) from Sennheiser, but at the moment the stock 3.5mm termination is the way to go if you want to stick to an original Sennheiser cable.
