The end result is a frequency response from 6Hz to 20kHz (no tolerance given). Other specs include a nominal impedance of 16 ohms, which is plenty low enough for portable devices to easily drive it. The maximum sound pressure level is specified to be 124dB SPL (1kHz/1Vrms), but I strongly advise against playing music that loud; it will damage your hearing in only a few minutes. None of this is a slight on the IE 300. As an IEM designed to bring home some of Sennheiser’s trademark sound at a price point favoured by more casual consumers, it delivers much more than that. Not only does it take its design cues from on-stage IEMs, with its fold-over, over-ear aesthetic, but the driver and technology inside the shell also have a storied history of innovation and manufacturing precision. I greatly admire Sennheiser headphones—I’ve had a classic on-ear HD 414 SL in my recording studio for 40 years. These days, the company also makes in-ear headphones (IEHs), including the IE 300, which was introduced at CES 2021. Dynamic range is also very decent, impressive even, with the IE 300 able to articulate subtle nuances and sudden bursts of volume in equal measure. When Hans Zimmer’s Mountains bursts into life at the 2-minute mark, the emotion communicated through the crescendo is palpable, while all the subtle details and effects in and around the main strings and piano strikes are clean and clear. Likewise, I was impressed by how the build-up to Max Richter’s Winter 1 wasn’t totally obscured, with subtle cues in the opening string instruments loud enough to enjoy, even at lower volume. Full disclosure: Sennheiser sent me a sample IE 300 for review in exchange for my honest opinion, without any deadlines or expectations. The opinions expressed in this review are entirely my own, so feel free to PM me should you have any questions or comments about your own preferences or experiences.

Like with many of Sennheiser’s IEMs utilising the Helmholtz resonator technology that first popped up in the original IE800, the IE300 has a boosted treble response that is simultaneously sharp yet restrained enough not to fall into sibilance or harshness. Again, the IE300 has a treble that is decidedly north of neutral so those sensitive to higher frequencies should stay away regardless, but this has always been Sennheiser’s strong suit in the IEM game so it’s good to see that they’ve at least maintained it. Spec-wise, the IE 300 is fairly ambitious, quoting a frequency range of 6Hz to 20kHz, 16 Ω impedance, a sensitivity of 124 dB (1 kHz / 1 Vrms), and a THD of < 0,08 % (1 kHz, 94 dB SPL). These are very similar to the IE 900, although the IE 900 extends further with even less distortion. In practice, I find the IE 300 very easy to drive, although it enjoys as much power as you can give it and will respond to beefier amplification, even though it’s not strictly necessary. This is fitting to an almost cinematic narrative level because the IE 900 was revealed at the same time as the news that the company's consumer division had been sold offbroke, as per the announced intention to do so earlier in the year. The nature of this sale is not a ‘clean break’ and Sennheiser looks like it will be involved in the development of future product but, until we know how that truly works in practice, what you see here is very likely the last of the Sennheiser home audio division products developed in the ‘old way.’ IE 300 ใช้ไดรเวอร์แบบไดนามิกหนึ่งตัว 7mm (Extra Wide Band) เป็นไดรเวอร์ที่ทาง Sennheiser คิดค้นออกแบบใหม่เพื่อถ่ายทอดย่านเสียงและมิติเสียงให้มีคุณภาพไปใช้งานในระดับมืออาชีพได้เลยครับ ตอบสนองย่านความถี่ 6Hz – 20,000 Hz ความต้านทานที่ 16 โอห์ม THD < 0.08% ( 1kHz,94 db) ความผิดเพี้ยนน้อยมาก ๆ และขับง่าย ต่อตรงกับมือถือเล่นได้เลยครับRight now, as I type this, I’m listening to the IE 900 playing Brian Eno’s An Ending (Ascent) both because I have a mild flair for the dramatic and because it contextualises where this headphone sits in the wider scheme of things. This is among the last, if not the last domestic Sennheiser product we’ll see before the new ownership arrangement starts to make itself felt. On the one hand, there’s a degree of sadness to this because, not only is the IE 900 the best earphone Sennheiser has made, it might well be the single best thing of the company's I’ve ever tested (it’s a three way tie between this, the original IE800 and the PXC550). If this is an ending, it is truly going out on a high. IE300 has a very good depth in it and very good imaging capabilities; Although as a result of which the soundstage suffers a bit giving an average width and quite decent height. Listening to Bassnectar – Reaching Out and Dream Catcher has similar impacts with very good bass response, imaging and instrument separation but fails to give a holographic presentation but the overall tonality and presentation is amazing that hit on the soundstage doesn't even come to notice if not listened critically. LOWs: crisp and very impactful. I get goosebumps and eargasms with a smile when crisp and punchy low sub bass notes hit The IE 300 earphones are designed and engineered in Germany and they feature a special German made 7mm XWB (Extra Wide Band) transducer. The IE 300 is a single dynamic driven IEM, but its performance is exceptional. More on that later in this article. These earphones charm the ear, but their treble and upper-mids hog the limelight; they don’t allow the mids enough room in the rendering of the texture of vocals. The mid detail is there – it isn’t as soft as a pancake as it is in some lower-end earphones. But the choice to emphasise the treble and bass leaves the mids noticeably recessed in comparison to other similarly competent pairs.

The ear hooks may give the Sennheiser IE 300 a sporty look, but these earphones come with no claims of water-resistance. Instead, this is a design borrowed from professional IEMs, the earphones a lot of musicians use to hear what they’re playing on stage. Key to the IE 900 is that Sennheiser hasn’t changed its basic preferred configuration to make them. Where many rivals are armature designs, with multiple drivers on each side, often supported by a dynamic driver handling the bass, the IE 900 has a single dynamic driver in each enclosure. This is responsible for the entire frequency response and the IE 900 uses an all new one called the X3R. This builds on the ‘Extra Wide Bandwidth’ principles that have been seen in the IE 800 and IE 800S and begins by increasing the size of the driver from 7mm… but only to 7.7mm. Bonus bass and treble seems like a technique that would be enlisted by a lower-end pair than this. But hearing it transplanted onto the Sennheiser IE 300, plus their great 7mm dynamic driver, is a recipe for good times. Instrument fundamentals in the midrange generally have a very natural, life-like timbre, as you’d expect from the tuning experts at Sennheiser. Guitar strings and piano strikes are probably more influenced by the bass lift than any residual treble peakiness, of which there is very little. Annelie’s rendition of Tomorrow, from her solo piano masterpiece Hetrz, showcases the rich, smoky overtones of the sustain pedal rather than the brighter key strikes, and while Joe ‘Satch’ Satriani’s guitar riffs in Always With Me, Always With You are clear and crunchy, they’re also nicely rounded with a slightly warmer edge. The build quality is excellent and with the soft, round edges the IE 300 looks comfy, high end and professional. As said, the Sennheiser IE 300 has a very plastic look at feel, but it’s actually very well built.When you have a passion for audio, detail matters: Created for audio enthusiasts, Sennheiser’s new IE 300 earphones have been crafted to deliver a high-fidelity listening experience anywhere you go. The Peer Gynt recording of Edvard Grieg’s “In the hall of the mountain King”. This piece has more dynamic range than most and gives the ie300 a chance to really show off the distance between the quiet passages while retaining detail and the elevated passages without loss of control of the low end. I began by trying the largest included eartips, both silicone and memory-foam. I have relatively large ear canals, so I need large eartips to achieve a good seal. The largest eartips that come with the IE 300 are about 13mm in diameter, and both types worked fairly well at sealing my ear canals—in fact, they fit me better than the tips included with most IEHs I’ve tried. The issue with the silicon tips may be a result of a slight warping of their shape, which was the state we found them in out of the box, but this is likely to be an experience that varies user to user, as is often the case with in-ear fit.

The venerable HD600, released in 1997 and based off the HD580 in 1993, later spun off to the HD650 in 2003 and then made cheaper in collaboration with Massdrop as the HD6XX in late 2018. The HD800, introduced in 2009 and then further refined into the HD800S in late 2015. The HD25, an industry staple in both the DJ and broadcasting world since 1988. And lets not forget the “concept headphone” models in the Orpheus, the HE-1, and various other “babies” in-between. Turning to bluegrass, I cued up “Suzanne” by Mo Pitney from the compilation album Industrial Strength Bluegrass: Southwestern Ohio’s Musical Legacy at 24/96. Once again, the IE 300 sounded clean, clear, open, and well-balanced from bass to banjo with great imaging and entirely natural-sounding tight vocal harmonies. IEM จากทาง Sennheiser แบรนด์เยอรมัน มาแนะนำครับ เกริ่นนิดนึง ผมรู้จักแบรนด์นี้จากเพื่อน ๆ ที่เล่นหูฟังบอกกันปากต่อปาก ในตอนนั้นที่นิยมเล่นกันก็มีรุ่น CX300 รุ่นยอดนิยม แต่ผมได้เป็นรุ่น CX280 มาครับเป็นหูฟังคู่กายเลย เสียงแน่นฟังสนุกทีเดียว The cabling is a dark grey and has a slightly grippy texture (more on this later), and has been reinforced with para-aramid (the type of material that the brand Kevlar uses) for increased durability and “thousands of bend cycles”. For the first week or so I used the silicone tips, and was never quite sure if the seal was quite right. No such problem with the foam tips.

My usual thanks to all my current supporters and shoutouts to my big money boys: The right earbud is labeled as: “IE 500 Pro” for model identification (the 400 Pros also have this, the 300s do not) In today’s review we’ll be taking a closer look at the IE 300 IEM: Sennheiser’s newest single driver, closed earphones. The IE 200 and IE 300 are both great IEMs that are priced in a generous way. I wish there was a space for both of these IEMs to exist, but only the IE 200 is readily available, and it’s not a bad trade-off at all. I think the IE 200 is a worthy upgrade from the IE 300, but there are some aspects of the later that you may personally prefer.

Bendable ear loops help keep the IE 300’s earpieces securely in place. Sennheiser IE 300 performance You probably could guess the verdict of this review since the IE 200 is now the lowest-priced among the Sennheiser IE-series. What if I tell you that you guessed wrong? The IE 200 is actually a more balanced sounding earphones compared to the IE 300, which offers prominent bass with sizzling hot treble, the IE 900 refined the treble transparency to the next level while keeping the bass controlled and less bloated. The IE 600 attempts to re-align the sound towards a more balanced, neutral sound and keeping the sound staging a little tighter, so it loses that airiness of the IE 900 but still presents excellent details. My sound signature preference: My preference is to have a great soundstage where the bass is impactful and delivers a punch that I can “feel” but does not over power the rest of the frequencies allowing for me to hear everything. Separation is important as well. The better tuned/balanced sound, the better.Sennheiser did have a brief stint with the pro-audio market, releasing the IE40 Pro, the IE400 Pro, as well as the IE500 Pro. Again, all IEMs catered to the pro-audio crowd (hence the “Pro” suffix) but now it seems that Sennheiser is ready to dip their toes into the audiophile pool once again.

They aren’t, but I hear more complicated and nuanced imaging from earphones and headphones that are significantly worse in most other respects. These earphones also have a little more mid-bass than I’d usually expect from an “audiophile” pair, which reduces their transparency a bit.
