Headphone Profile

Sennheiser IE 300

Sennheiser IE 300

Sennheiser IE 300

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.

Sennheiser IE 300

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.

Sennheiser IE 300

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.

Let’s take a look at the specifications...

  • Frequency response: 6 – 20,000 Hz
  • Impedance: 16 Ohms
  • THD: <0.08%
  • Sensitivity: 124dB at 1 kHz, 1V
  • Cable: 1 meter (3.3 feet) total
  • Included accessories: (3) pairs of silicone ear adapters (S/M/L), (3) pairs of memory foam ear adapters (S/M/L), cleaning tool, deluxe travel case

    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.

    5.0 out of 5 stars The Best Sennheiser IEM with caveats
    Reviewed in the United States on April 20, 2021
    Verified Purchase
    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!

    5.0 out of 5 stars Fantastic performance

    This is the "home" pair of earphones you always want to return to. The fit, comfort and noise isolation are all just right. I'm a fan of the 360deg swivel. Sound is simply phenomenal - very musical, fun and non-fatiguing. It features a typical Sennheiser sound: V-shaped, yet highly detailed and smooth; it can be said to have the Sennheiser 'veil' (because of this sound signature). Forgiving and pleasant. Plenty of bass, and slightly emphasized treble (but never fatiguing). Amazing soundstage and good imaging. This specific sound profile has the advantage that you can listen at above-average volumes, and the loudness is never tiring, always beautifully diffused (unless you go crazy high of course). Very refined, detailed, and SO comfortable. Can be worn for hours on end and you'll enjoy every minute of it.

    This is my 2nd Sennheiser product, the previous being the HD 598 SE open-back headphones, and I am very satisfied. This review just gives an overall picture and focuses on the sound, which is just sublime. Another point of note is that these earphones cannot be said to have an audiophile sound - although it definitely has audiophile-grade quality and build - because I understand an audiophile signature to be more neutral, more unforgiving and exact. This leans towards purely music lovers, anyone who can appreciate phenomenal sound reproduction of their favourite music - as the box says, "High-fidelity earphones for sophisticated music enjoyment".

    1.0 out of 5 stars DONT BE FOOLED BY THE SALE, THE OTHER REVIEWS ARE RIGHT
    Reviewed in the United States on January 14, 2023

    You might be like me, wanting to give the IE 300s a try despite all the bad reviews because it's on sale and Sennheiser is known for their amazing quality. Well, at least in the past that is. Now, my perspective on Sennheiser has completely changed, and you should seriously consider rethinking this idea of yours to purchase these.

    First off, the sound that's produced from these are amazing. Music, videos, games, everything sounds great from these IEMs, and even better if you plug them into an amp. Despite the amazing sound, it's quite obvious after the first couple seconds of plugging these headphones into multiple different connections, that I was either given a faulty pair, or this product line is just complete trash. The left bud crackles randomly and the audio will completely cut out from time to time, even when you are sitting still and not moving your head / cables. Also, like other people have pointed out, anything the cable rubs up against while the buds are in your ears, will cause instant ASMR in your ear hole. My shirt, my desk, my arms and anything else the cable touches all make lovely disrupting sounds in my ear when wearing these. Usually this is pretty easy to ignore, however during a long video or if using these while gaming, it can be very distracting and ruin immersion entirely.

    Don't buy these unless you want to play the lottery with your IEMs. You may not have any experience like mine and the countless other people who are in the same boat as me, but why don't you go check on their support links with Amazon. Oh, and their phone number linked their too. It's all disconnected, and Senn hasn't responded to my email that I sent days ago through their newly hidden contact center. You are SOL if your product dies after the 30 days, so best of luck.

    5.0 out of 5 stars I Thought These Were Headphones
    Reviewed in Canada on June 2, 2021
    Verified Purchase
    I had given up on trying to find IEMs that could stay in my ears untillll I saw Z Reviews video of the IE300 on April 20th. After I finished watching his review I immediately checked the price on Amazon.ca and saw it for $280 (Ships from and sold by Amazon.ca) which shocked me cause it is $400 at MSRP here in Canada. I watched other reviews from other YouTubers such as DMS, Joshua Valour, and Chrono from The HEADPHONE Show to hear more opinions and bought them afterwards.

    Once I got them I tried the smallest foam ear tips cause my ear canal are extremely small and they are pleasant to wear that it fits like a glove for me! Extremely lightweight cause of the plastic build and compact shape. The cable has this memory retention thing which is annoying to get used to but it actually makes the IEMs stay in my ears forever without budging.

    For sound quality I would say this is a very fun and enjoyable listening experience. It is not trying to be a flat and accurate tuning here, so do not consider this product if that is what you look for. It feels like I am listening through headphones because it has a nice sense of space around you with good imaging and presentation for vocals. I thought I would not like this tuning cause I enjoy vocals the most with my music but there is just something about these that make it feel special. When it comes with female vocals that sound soft, it just feels so dreamy with these IEMs it makes me melt (Example: MISIA - Everything). And even though the vocalist is not in your head, it is more like they are in front of you like you are on stage with them as they perform because of the soundstaging this is capable of. Even though vocals are not as intimate as I like, they still get that spotlight with these IEMS. However, these do lack the timbre of like other Sennheiser series like 58X, 6XX, and 660S, which is what I miss a lot but the IE 300 are still so so so much fun to listen to. Sometimes with the highs it does hurt my ears but that is when I listen to music at higher volumes than normal. Oh there is also a lot of bass. It says it can go all the way down to 6hz and I believe it. I thought I was a basshead but man it is WAYYYYY too powerful for my liking. But... It is also awesome when you in the mood for it lol (Example: ZHU - Only).

    So was it worth for $280? Heck yeah! What about $400? Now that is a tough choice cause there is many other options you could pick in that price range. I personally would have bought these over anything else because I prioritize comfort more than sound quality when it comes to IEMs cause I enjoy long hours of listening and being active without worrying they will fall out. For me these IEMs are all that I could ask for which is why I give them a high praise.

    One thing I absolutely hate about these IEMs is the recessed MMCX connector... Sennheiser you guys thought you were so cool making them detachable and swapping out cables but nope. You guys suck for doing that. I love this cable but not everyone does.

    Oh yeah I am running this off of a BTR5 non-balanced, stock foam tips, and sources are FLAC files and Spotify streaming. Does not need a lot of power so this and the Apple Dongle would be the best pairing for the money.

    Update [10/18/2021]: I voided my warranty and used an exacto knife to shave off the R&L colour indicators which also makes the MMCX connectors recessed. I did it so I can use FiiO's UTWS3s and IT WORKS muahahahah. I recently found out about the UTWS5 but I am happy with mine since it is enough to power the IE300s (but if reviewers say it's amazing to upgrade I wouldn't mind getting it...). So now I have very amazing TWS earphones that are lightweight and comfy :D

    2.0 out of 5 stars Disappointing
    Reviewed in Australia on October 3, 2023
    Verified Purchase
    Very uncomfortable to wear, mainly due to the cable being too large or unflexible and stiff.

    I was unable to get a good seal with any of the included tips as well as my own (i have 7 different sets of tips - none of them fitted, too small for some reason)

    The connectors seemingly at random would cut in and out

    I was unable to confirm the sound quality due to poor seal, however it did have a very poppy feel to what Ive heard so far even without a good seal

    If youre planning to buy this, be ready to fork up some more bucks for additional replacement parts

    El equalizador en V se nota mucho y los eartips de memoria foam son muy comodos y aislan el ruido muy bien, buenos para la mayoria de musica pero tiene sus peros, son imposibles de poner rapido y aun mas dificiles de poner si tienes el pelo largo al rededor de la oreja.

    5.0 out of 5 stars An excellent IEM form factor, with "premium vanilla" sound
    Reviewed in Canada on March 20, 2023
    Verified Purchase
    I am someone who generally does not like the IEM form factor; I don't like the plugged-ear feeling, and I have a hard time keeping them in place. This doesn't escape those issues, but as IEMs go, its hard to do much better than this. The body of these IEMs is exceptionally small and compact (a lot of IEMs have *very* chunky bodies), and it comes in the box with a good variety of tip options, including foam.

    The sound quality is what I'd call "premium vanilla". It doesn't have much in the way of personality, it's mostly flat with limp bass (even with a big EQ boost the bass is still soft), but it's clean, detailed, and transparent. The sense of soundstage is relatively wide, for an IEM. I've also tried the IE600, and those were similar, but even cleaner and more detailed--though I think the IE300 is the better value, especially if on sale.

    I've had them for many months now, but haven't been using them much in the winter, because I find it painful to wear a hat over an IEM (and when I'm indoors at home I prefer using open-backs). The hat over my ears adds extra pressure onto my ears, and it starts to hurt after about 5 minutes. Apart from that, they're a very good portable headphone option, they pack a lot of sound quality into a small package.
