Sennheiser IE 100 Pro-Black in-Ear Monitoring 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.

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.
