Sennheiser IE 100 Pro-Clear in Ear Monitoring Wireless Headphones for Musicians On Stage & Monitoring

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: 8/10Value for money: 8/10Comfort: 9/10Appearance: 7/10

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.
