Detailed Sound Everywhere

The driving force behind the IE 300 is its refined 7mm TrueResponse transducers that deliver breathtaking acoustic performance in a surprisingly compact design. The diaphragm, reinforced with new materials, dramatically improves response times and consistency across the frequency spectrum. Minimized resonances and enhanced vibration speed bring clarity to higher frequencies, warm mid-tones, and clean, powerful bass response with low harmonic distortion. Transitions between frequencies are clean and vocals retain their silky character, delivering studio-quality sound directly to your ears. XWB transducers reproduce sound that is unique to the Sennheiser audiophile legacy, and are developed and manufactured to exacting precision in Sennheiser's world-class facility in Germany. Despite its small size, the output is larger than life, giving you intimate access to all of your favorite tracks without any issues.

Air Traffic Control

A key element of the IE 300’s balanced acoustic performance is the back volume—a miniature chamber-within-a-chamber that helps manage the flow of air behind the transducer. The direction and overall volume of air is controlled with precision as it travels through and exits the transducer system, delivering a discernibly defined bass and mid-range experience. We further observed a natural increase in the ear canal’s resonant frequency when sealed by an ear tip adapter. The reduced air volume produced a masking effect that obscured critical details within the source signal. A frequency absorbing resonator chamber was applied to reveal those subtle nuances once again. This collection of technologies works together in perfect harmony, establishing the IE 300 as a go-to benchmark earphone when sound quality matters.

In-Ear Peace

The IE 300 ensures that you can enjoy a thrilling hi-fi experience wherever you are. Imagine having a personal, expertly tuned listening room at your command—ready to provide sonic bliss at a moment’s notice. Because the IE 300 shields you from ambient noise, your music stays in control of every listening session. The reduction of ambient noise diminishes ear-fatigue for better, longer listening sessions in practically any location you could dream up.

Inspiring performance

A universal design that feels like it was custom tailored just for you. Included with the Sennheiser IE 300 are (3) sizes of silicone ear tips and (3) sizes of memory foam ear tips—the latter conform to the unique shape of your ear canal for maximum noise-isolating performance. This earphone’s geometry is more than just sleek form—it never gets in the way so that nothing stands between you and your music while on the move.

It's all about connection

Outfitting the IE 300 with a detachable cable was an obvious choice; however, audiophile-grade sound demands a matching level of mechanical reliability. Our engineers were tasked with delivering peerlessly dependable compact earphones that could withstand any wear and impact. To achieve this, they started with gold-plated Fidelity+ MMCX connectors—known for their rotational durability and contact integrity—and seated each within a recessed, 4.8mm-wide socket beneath the housing's surface. This yields outstanding strain relief and stability, providing users with the utmost confidence that their IE 300 will always be ready to perform—especially when combined with our para-aramid reinforced cable rated for thousands of bend cycles. A stereo 3.5mm / ⅛-inch plug offers the standard connection to digital audio players, headphone amp-DAC combos, laptops, mobile phones, audio interfaces—the number of devices whose sound is waiting to be rediscovered is endless. Balanced 2.5mm and balanced 4.4mm terminated cables will be available (sold separately), opening access to the new generation of balanced output devices popular in the audiophile community.

One of the best headphones for the price

First of all, I tried and bought this product from the Akasya experience store, and I saw Comply Foam, which I will talk about in the following parts, there.

Although it is not the best headphone I have tried so far, it is one of the best in-ear headphones for its price. But it's definitely the most comfortable in-ear headphones I've ever worn.

Let's start with the bad first. The ear tips that came in the box were not satisfactory for me. The silicone ones are very thin, they never stop sound and depending on the movement, they can cause the bass to leak. Moreover, when I tried to remove the attached medium-sized silicone tip, it was torn. As for the sponge ends, it was fine, but not for me. They're too short for my ears. The next day, when I went back because the ear tip was torn, I saw the Comply Foam sponge tips. I would recommend these tips to anyone who is going to buy this headset. Although it is a bit more complicated to put on the ear than normal silicone tips, it is extremely comfortable and makes you forget its existence after 10 minutes or so. It has incredible noise canceling, even better than Airpods Pro's active noise canceling. I don't know how long they last, but according to their comments, they need to be changed every 3-4 months. They're a tad expensive. When I bought it, it was around 370TL, but everyone who will buy this headset should definitely buy these tips. Due to the noise reduction, you can focus entirely on the music, not the external sound, especially if you are in a noisy environment.

I don't like the cable of the headset either. Although not one of the worst cables I've seen, it's cheap compared to this headset. First of all, it has a smell that I don't like and has a slightly sticky texture. Because of this, all the friction can be heard. Even the cable that comes out of the box of a 6 times cheaper KZ headset gives a better quality feel. The good thing is, since the cable can be removed, you can optionally attach different mmcx cables. I haven't tried it, but there are people who use a 4.4MM balanced cable with this headphone because the cable broke.

Let's get to the structure, enough bad thoughts. The headset is extremely small and has a body made of the best plastic I've ever seen. When you look at it, there are yellow red white dots on it. It's like you're looking into space. If you don't use it badly, it has a lifetime structure. Although it is not made of stronger Zirconium or aluminum like its older brothers IE 600 and 900, I have never seen a higher quality and durable plastic in my life. Again, the most comfortable earphones I've ever used. Due to its small structure, you can easily lie on it when attached. And after I put on the Comply Foam tips, I couldn't drop it from my ear even though I shook my head enough to cause a brain injury and pulled the cable. Headphones have now become part of my ear.

Let's get to the sound quality. One of the best sound quality headphones you can get at this price. The sound is as natural as I expected, the clarity and tonality are top-notch. The bass is pretty balanced. It can easily respond to any setting, whether you EQ and root it or lower it. Although the stage width cannot compete with an on-ear, especially an open-back headset, it is legendary for an in-ear headset. The separation of vocals is exciting. It's good enough to compete with very high-end IN-EAR headphones, even though it's entry-level. If IE 8, 80 etc. If you've used Sennheiser's old entry-level headphones, I definitely recommend switching to this one. It uses the technologies that Sennheiser uses in its high-end headphones such as the IE 900, and it is much more comfortable and extremely good in sound quality. Here, I am saying the inside of the ear by pressing, because in-ear headphones and on-ear headphones are incomparably different categories.

Although you can use the headset without an extra DAC thanks to its low impedance, I definitely recommend using it with an extra DAC. Because that's how you see the actual performance of the headset. In addition, I recommend you to use a product such as Fiio KA1 or KA3 as an entry level, Fiio Q3 or Q5s as an intermediate level, Chord Mojo 2 as an upper level, or Astell&Kern SP2000 that you can try in the store. They can reach a level that can make you deaf in terms of output power, and they can give a much cleaner sound than the phone or computer's own headphone jack.

In summary, Sennheiser IE 300 is one of the best and ideal music listening headphones in terms of sound quality that can be bought at this price. Also, thank you very much to the acacia store for the experience. Staff are very friendly and helpful people. They helped me with whatever I asked for and allowed me to try almost all the headphones and amps for quite some time. I would definitely recommend you to go and try it out. Moreover, I am a difficult person in these matters. I would like to thank the employees of Akasya hifilife for putting up with me and contributing to me. There are 100 places to sit in the store, go and try all the products, I recommend the store experience until the end.

Unlike other brands, it is the headphone that Senneheiser launched with a single dynamic driver. Its older brother, the ie 900, also comes with a single dynamic driver.

It's a very small and unpretentious headphone. It has a structure that I like very much because it does not attract attention. it almost disappears in the ear, so it can be used while sleeping.

The eartips that come in the box are not very satisfying. Although it comes with 3 silicone and 3 sponge tips, I haven't been able to find the tip that fits me for a few weeks.

cable supports mmcx connection, but unfortunately not all mmcx cables are compatible with sennheisers. this is a minus.

In the reviews, it is mentioned that the cable has a microphonic effect. I have absolutely no such thing. I don't hear any sound coming from the cable while playing music. maybe it can be heard when music is not playing, but I don't know why it gets stuck in the ear without music.

The sound it gives is not flat. quite colorful on the contrary. Sennheiser aimed to listen more fun than realistic in this earphone. The bass is quite forward and powerful. but it does not mix with mids at all. this positions the headset in a different place compared to its counterparts. The mids and trebles are just as they should be.

I think the striking part of the headset is instrument separation and positioning. Although the stage is quite wide for an iem, it is behind the earphones that completely cover the ear. despite that, instrument separation and positioning on stage are great. you can hear the position of each instrument and all the details it outputs.

vocals are usually positioned in the middle of the stage while the pieces are being arranged. With this headphone, one can focus so much on the instruments that the vocals don't stand out much. but when you pay attention, both male and female vocals are very successful.

I use it on iphone with apple's own adapter. I never felt the need to turn up the volume all the way. In the reviews, it is said that this cable (including a dac) is sufficient to power the ie 300. I haven't tried it with a different dap or dac, but I don't think it will make much difference. One of its best features is that it can be productive even with a phone.

According to its price segment, I can say that it is one of the best in-ear headphones that can be bought right now.
