SennheiserIn- Ear Audio Monitor, Clear, Wired (508941)

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.

Bonitos, cómodos y excelente sonido.

Tenía debate sobre cuáles in ears comprar.Mi esposo tiene los Shure Se215 y me gustan mucho como suenan, sin embargo con ningún tipo de almohadilla ni talla me sirvieron nunca, ya que mi oído era demasiado pequeño, con Sennheiser encontré el adecuado para mi, ni moviendo demasiado la cabeza, ni hablando, ni nada se llegan a salir o mover del oído, tiene un excelente agarre. Trae diferentes tallas de almohadillas y puedes escoger la que mejor se adapten a ti.Me decidí por los Sennheiser IE 100 PRO, a ciegas y significativamente superaron las expectativas, pese a que mi oído es muy pequeño, se adaptó perfectamente, y hablando de sonido, supera por mucho a los Shure Se215, en una comparativa muy específica, con los IE 100 escuchas cosas que no se aprecian con SE215.Opinión final: después de una comparativa real, me quedaría mil veces con los Sennheiser IE 100 PRO.Si a Sennheiser IE 100 PRO hubiera que verle algo que mejorar, sería un poquito más de graves, pero nada que una buena ecualización no resuelva.Y algo realmente importante para mi es que no trae un estuche qué realmente proteja, que si lo incluyera, realmente tendría mil puntos más a favor.Después de ahí, todo excelente, los amo!!!

Great sound! Cancels all noise around you. I use them mostly on airplanes and I can not hear the babies crying lol. Great price too. Definitely bass there !

The media could not be loaded. Gracias ☺️

I found out that I'm an audiophile with these things. I was a long time lover of the Bose QC 20 NC wired earbuds - tried to replace them and realized that anything you can find online today are all knockoffs with good sound isolation but horrendously cheap tinny and thin sound.So, I went on the hunt. These things won. Big.Great price point for what you get too.They have an amazingly crisp yet dynamic feel. A fairly neutral profile that very much highlights the essence of what the music was intended to sound like. Super fun to listen to plugged into my computer on Qobuz. Great accurate bass, trebles have a realistic studio quality feel and the mids are present but not overpronounced like some 'neutral' devices. I love, love, love these things and think you will too...

I just knew with a name like Sennheiser, some good reviews, and a moderate price that I would be able to use these in-ears successfully with my existing monitor tx/rx system. I already knew my system was great with my mid-level AKG headphones, but don't want to wear full headphones all night onstage. I carefully unpacked these buds and hooked them up just like I had the 'phones, and the sound was atrocious. Full fuzz on the low notes of my guitar, and lack of any definition on the mid and upper registers. I was prepared with a 10-band equalizer to fix any issues I might have. After rolling out all the sliders from 31hz to 250hz, the fuzz was gone but I couldn't get any definition throughout the spectrum no matter what. I finally came up with a compromise for the guitar and checked my Shure SM57 mic. It sounded very much like a toy mic that would be included with a child's first karaoke set. I never succeeded in getting the mic to sound passable, and anything I adjusted destroyed the flimsy compromise I had made for the guitar sound. I guess I will use my in-ear system (with headphones) for rehearsal at home and continue to use floor wedges for live work. These are going back to the seller.
