IE 100 Pro Wired In‑Ear Monitors | Red | Precision Dynamic Drivers | Detachable Cable | 20 Hz–18 kHz FR | Ideal for Musicians, Live Monitoring, Studio Recording & On‑Stage Performances

I have listened to the lower variants of Sennheiser and I wasn't impressed. I have used Beoplay earset & h3, Focal sphear s, AirPods Pro, Beats Studio and several other budget ones. I have consistently rated the h3 as good. Even AirPods Pro sound good in movies with spatial audio and less with music. On my budget, I was considering shure aonic 215 and Sennheiser ie100 pro. Although I saw more people recommending shure, l was confused as I couldn't get hands on an auditioning piece. I was able to see a YouTube piece which have compared these two earphones side by side with an elaborate setup by TekitouSoundComp. The IE100 Pros had a great rounded audio with clear vocals and decided to buy it. At 6300, I got myself a decent bargain and I am not regretting it. To enhance the sound, I would suggest the usage of a small headphone amp. I use the ifi audio's go-link. It has an impressive sound stage. Played a few tracks, Hotel California (remastered), Coldplay's Yellow and Hymn for the Weekend, Chain by Fleetwood Mac, Blue Heron by Sarah Jerosz, Baby by Clean Bandit and all played with great clarity - both in vocal as well as instrumental. The bass is more than sufficient and does not overpower the music. The sound is well rounded. The mids and the highs are good and does not shrill. Neither does the mid overlap with the highs or the base. I watched a few TV series with this and I wouldn't recommend this for movies. Not that it sounded bad, but once you have heard the airpods pro, you will be addicted to the spatial audio. The isolation with the silicon tips itself is pretty decent and the headphones are very light. Fit is also good, however, if there is someone who needs to talk to you, the headphone must be removed and unlike the direct iems, this takes slightly more time to fit in the ears due to its design. This portion is annoying. This earphones was able to take up any sort of music thrown at it, rock, jazz, pop, bluegrass. These earphones are audiophile quality, and has no mic. They are wired. This piece of information is important as many using headphone amps may not prefer a mic. These are the go-to earphones if decent bass and clarity are top of your list. I am pretty s(h)ure to go with Sennheiser.

This is my first iem experience, I've been used to wired earphones from JBLs, Skullcandys and audio technica CLR100 before. So this won't be a professional review but my personal experience. Quality and comfort : The build quality feels solid, the red colour looks great and these are really comfortable even for long hours. Absolutely no complaints in this department. Sound quality : The first time I listened to these I was totally impressed by the level of detail and the soundstage that this can produce. Every single detail in the song or the recording is audible. Whenever I'm listening to a live recording or some raw ambient sound (like asmr) the sound feels completely natural and real. Coming to the frequency response and tonality, in the very beginning it took some time for me to adjust to the high end sparkle or presence of these. It was feeling too sharp. Maybe because I'm used to consumer earphones which almost always tend to be bassy and boomy. But now since I'm used to it everything sounds great. Bass is present but only as much is needed. Mids and vocals sound really amazing. And the treble clarity is amazing too. Overall to my ears, I still feel these are slightly more focused towards mids and highs but if you're listening at sane volume levels it sounds perfect and extremely detailed. The strings in the background of some songs, the cymbals, the clicks.... These are some of the sounds which you would rather miss on cheap consumer earphones but you can hear all those with these. And the vocals on the songs sound amazing too. Overall I'm satisfied and still going through the journey of getting myself adjusted to these iems and experiencing the detailed sound from them.

I got this product as I was looking to have a upgrade from my previous Sennheiser cx275s which by the way I had absolutely loved from the very first day (great product, worth the money). But to my surprise the ie100 pro's didn't sound very superior to the cx275s given the fact that they are 4x times the price compared to these. Sound staging and sound clarity are great but nothing exceptional if you've previously been a CX series user then you already know (I've tired the cx275s and my assessment is based only on that). Those models in that price range are still the best ones, sadly they aren't being manufactured anymore except for some two models which I haven't tried. However where the ie100 pro's does shine is at noise cancellation, they are quiter. They do a better job at faithfully sending back the feedbacks of the instrument you're playing if you are a musician as I tried, or even if you want to hear you own voice on stage I believe for monitoring, infact they are IEM's afterall. If your looking for some wierd driver enchancer to make music sound great and magical forget these, you're better off with other brands and you'll get one for far lesser price. But if you've been a Sennheiser user for a long time and in love with the Sennheiser house sounding then probably you won't regret buying this (if you're looking for monitoring). If it's for music/movies you're going to hear sounds as they are, nothing enchanced nothing magical! Just as they were recorded. The better the recording the better the hearing at the other end. These IEMs does quite well what they were designed to do monitoring!!! Having said that I wonder how different will the higher pricing models be compared to these ones.

It’s a classic wired headset for the ones looking for non Bluetooth options under 10k. Clear and precise sound. Takes a bit getting used to wearing it and fit into ears. Expected Sennheiswr quality.

It’s very good.

Costlier

Very good in air i am using it since 1.5 years good quality and till now the sound quality is same

I liked the vocal tone it produces, also, I would like to mention, I know as entry level IEMs, there are options available from KZ audio, 7Hz etc. but in my opinion, it’s worth spending more and getting the Sennheiser’s, especially if you are vocalist, keyboardist or guitarist, basically for melody section… People say they didn’t feel much bass, but for me, the lower end punch is just adequate, not like any bass boosted cheap earphones… Fit was also good, gets locked perfectly into the ear, might be discomforting for some people after a long usage, but that’s the case with most of the IEMs, so no complaints for it from my side at least, stereo imaging is just great!

I rated 5 stars because they work for what I want (monitors for guitar practice). Pros Extremely light and comfortable Fit very well to the point I forget I'm wearing them. Audio quality good enough for my purpose. Probably won't fall even if you get a kick in the face. Cons You won't get a lot of bass (again, this is not for day to day audio listening) Audio isolation really depends on how well the tips fit your ears, don't expect magic to happen. These are by no means a super high level pro device but for my in house guitar practice it is amazing. Don't buy these expecting you are going to get concert grade IEM. My only regret is that the wireless version is a couple dollars more, probably would've got that one if I knew before.

Halten sehr gut in den Ohren auf der Bühne, selbst beim Tanzen mit den wildesten Kopfbewegungen. Sound auch super, leistet mir seit Jahren gute Dienste auf der Bühne.

Very good earphones for a good price

Um pouco mais basshead que o resto da linha Sennheiser. Extremamente confortável e sonoridade impecável.

These are going to be my first dip into pro-ish level in ear monitors. When it came to other iem's that I have tried, I have only ever bought consumer level in-ears and some of the budget oriented monitors from KZ like the ES4 and ZSN Pro X. This is actually my first Sennheiser as well so I was rather excited due to the company's lineage and experience. Inside the box was nicely laid out and came with everything I needed. The only gripe I had was the little "bag" that was meant to hold the iems in. It's one of those "snap bags" but instead of having a magnetic clasp to keep them closed, its just two bits of stiff plastic that keep it closed by simply being rigid, and if you want to open the bag you push in the sides to snap it open. They really should have included a zippered bag of some kind because that would have been simpler. The comfort of the monitors is simply great. They're small and could fit into most ears and the stiff over ear hook can easily be bent into any shape to fit any ear. Some might not like the wire design but I think it works out just fine. One very important thing to note about the silicone and foam ear tips is the cylinder of foam on the inside. Please take care when switching out tips because this foam is CRUCIAL to keeping the sound profile right. Yes, even though you can swap out the tips for more comfortable ones, you will have a VASTLY different sound profile due to the lack of dampening foam. Also, be sure to double check the nozzle itself because it too has some foam inside. For the most part, just be careful when switching tip sizes and use the cleaning tool to orient the tubes of foam so they sit correctly inside the nozzle and ear tips. I know it sounds like a hassle, but once you are aware of it, there should be no issues. For the sound quality. I have to say that these things are well balanced with some boost in the trebles that add a bit of brightness to each song. Snare drums and cymbals sound a bit more forward, but this is where the small fault comes in. There will be some songs in which the "S" and "T" sounds from vocalists will be a bit harsh, but not unbearable. Think about how recording a voice sounds like without a pop filter and you will get the general idea of what I'm talking about. This doesn't mean the sound is totally bad, far from it. It's just a warning that some tracks with certain lyrics will not sound the best unless the mastering of said track is a bit warmer. I have tried many genre's with these monitors and I will say all of them are pleasing and detailed. Even the bass is well tuned and you can get a nice thump, nothing that is head rocking and muddy but good enough. I will say that these do fit within the pro range and have a rather flat curve, in spite of what you might see on some frequency response graphs. I will say that minus the occasional shrill tracks you might run into, these will fit most, if not all genres of music. In the end, these are indeed pro level in-ears that you can get for a mere $100 and they will not disappoint. If you want to hear familiar tracks in a different way, I would recommend these. But also be sure that you are listening to a good source because the clarity of these in-ears will reveal badly recorded or low quality sound files very easily. A definite must-have for music enjoyers.
