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

Sound quality: neutral sound, a bit on higher side. Low is very good and clear. Sound signature is really of my taste. Crystal clear, crisp, on point sound. Most noticeable attribute is sound stage. Very wide spacious sound stage. Build quality: very comfortable and light. Best fit in ear. But feels delicate specially on the point of connectors. Connector: the connector is not typical ‘MMCX’ type. It is Sennheiser exclusive connector. This is the only drawback i have found. A universal connector helps in having choices over buying different quality and of different length of cable. Though the cable quality is very good. Soft and durable. Bluetooth connector: Bluetooth connector is just for casual listening. I noticed a huge difference in sound stage while shifting from wired to Bluetooth connector. With Bluetooth connector it sounds just like any other Bluetooth earbuds half the price. So I never use Bluetooth. It is just for ‘just in case’ type of purpose. Overall I found it to be really good sounding and best fit among all other earphones in my collection. I have bought it in 8.7k with Bluetooth adapter which is a great deal. ** The wireless version is not just wireless. It comes with both 'Bluetooth adapter' and '3.5mm cable'. So wireless version is basically the wired version along with an additional Bluetooth adapter. See the box contains in my uploaded picture.

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.

I love these IEMs. Probably will be nitpicking things that are stopping it from being the greatest pair of affordable IEMs ever created. Cons: 1) It looks archaic. The two dangling modules look ugly. I wish Sennheiser comes up with better looking blutooth modules in the next version that wraps around the ear and doesn't have flimsy wires like the current one. No complaint with 3.5 mm wires though. 2) A little more range. I like to have the freedom of walking around different rooms while forgetting about the range of a BT earphone. So when I go a little further than expected, the earphones start crackling a bit. A little more range wouldn't hurt anyone. 3) I've noticed my right bud has a noticeable driver flex. Not annoying. But I notice it from time to time. 4) Poorly recorded music sounds poor. Not a con, but the IEMs do justice with clarity. Any unwanted distortions become very apparent. 5) I use it with Windows OS as well. It's an absolute nightmare with windows. Connectivity issues, voice lag, poor quality while calling. It's a whole package. All of it could be solved if Sennheiser made a native control app for windows. Plus, if it also had an Equalizer. Pros: 1) They sound good. Good bass, decent mids and treble. The stock tuning sounds great. Though I have noticed distortions while using tweaking the frequencies to the extreme ends on an Equalizer, but nothing too serious. 2) They are cheap if you manage to get a good deal on them. 3) I love the interchangebility of wires. I edit music with wires and casually listen to it without them. It also means that I don't have to throw the pair when the wires go bad. I can simply get new connectors which is cheaper in the long run. 4) They're mad comfortable. I had a pair of galaxy buds, this made them look like ear dumbbells. I can wear this for hours with 0 discomfort once I get the fitting right. Verdict: Sound: 8/10 Value for money: 8/10 Comfort: 9/10 Appearance: 7/10

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.

This is definitely the worst tech purchase I’ve made in a while. For a brand like Sennheiser and a ₹10,000 price tag, I expected significantly better quality across the board. Sound & Build: The sound quality is just okay—there is absolutely nothing extraordinary about it that justifies the cost. Worse, the construction feels incredibly cheap and plasticky, completely lacking any premium feel. The Dealbreaker (Bluetooth & Mic): The absolute worst part of this package is the Bluetooth adapter. The call quality is practically unusable; it's nearly impossible to hear anything meaningful on the other end. To make matters worse, the microphone seems to pick up every single ambient sound in the room except your actual voice. Battery Life: Rounding out the flaws is the terrible battery life on the wireless module, which drains far too quickly for reliable daily use. Verdict: I strongly advise against buying this. It’s severely overpriced for the poor experience it delivers. I wouldn't recommend this to anyone.

Costlier

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.

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