Sennheiser IE 100 PRO BLACK In-Ear Monitors | Dynamic 10mm Broadband Transducer for Powerful, Precise Monitoring | 1.3M Cable & S/M/L Silcone Adaptors Included | Black (508940)

I spend a lot of time each day doing video/conference calls with virtual teams from across the globe - and that in itself has so many issues wrt to dealing with various audio issues - different accents, people speaking quietly, louder speakers, distortion on the line, audio breaking up, etc. etc. Thereby audio (listen and sending) is critically important - I need to be able to CLEARLY HEAR people and for my voice to be clearly heard.I am currently using a Blue Yeti mic as my voice input (which is just outstanding), and I NEEDED a good pair of in-ear earphones ... all the 'good' earphones I have tried so far put a lot of emphasis on base ... which is great for music listening, but not so great for listen to such a vast difference of people speaking.I needed a pair of earphones that I could use WITH my yeti mic that provide good CLEAR and CRISP voice (I don't need/want a base bias set).These earphones are PHENOMENAL - the the vocal audio is so CLEAR and CRISP.As for listening to music using these (although that is not the main purpose I will be using these for) , when using the BLUETOOTH adapter, as with ALL BLUETOOTH Earphones I have ever tried, there is a definite lack of max volume but there is great base available and the vocals are so much clearer.Using them wired, then there is no problem with cranking up the volume to as loud as I want - at VERY loud volume, these still provide fantastic performance with no distortion.These are by far the best In Ear earphones I have tried as a output in conjunction with my yeti mic as the input.Overall, at £122 (at the time of review - September 2022), sounds expensive, but I would say that is great value... I would definitely recommend if you are looking for decent in-ear earphones that provide clear and crisp vocals, decent amount of base AND can be used wired or wirelessly (BT).So yes, expensive, but oh so worth it - an easy and definite 5 ⭐⭐⭐⭐⭐ imho.

AMAZING quality and sound canceling in ears. The cable length is perfect and doesn’t get tangled easily. The sound is super clear and the bass is boosted which I like

Thought these sounded really tinny out of the box, but then I noticed the medium-sized ear tips seemed to be a fair bit smaller compared to others I have. Swapped them out for the large ones and the difference is night and day. They now have a really nice, balanced sound, although can still get a bit too bright for my taste at higher volumes.Comfort, fit and aesthetics all pretty good, although only 4* as you could get better sound from a Chi-Fi IEM at this price point. However, if you prefer to stick to established brands, you’ll be happy with these.(Bought for casual listening with an old iPod classic)

These Sennheiser IEMs were purchased for one specific purpose, which was to provide me with a nicely isolated and high quality fold-back audio mix on stage whilst performing. The earbuds fit well into my ear with the rubber grommets supplied, with the option of other sizes in the pack for different shaped ears. I put them on back to front first of all, and whilst they fit OK, they do work a whole lot better the right way round. The part of the cable that curves over the top of your ear is pliable and comfortable, ensuring a comfortable fit.Without going to the trouble and expense of going to a specialist to get a mould of your ear made and then a perfectly tailored pair of IEMs, this is an excellent and cost-efficient alternative. I wear them for hours at a time and they remain comfortable. Sound isolation is good, so you don't have to have the volume cranked up to the point that your ears ring after prolonged wearing.A pleasure to use and exactly what one expects from this brand. Recommended.

Great sound but an absolute nightmare to actually get them in your ears..

These were purchased as "used - very good" and turned up in all of the original packaging with all accessories.Easy to follow instructions.Easy to pair.Happy with the selection of ear fittings.These are a great pair of in-ear bluetooth monitors. I'm only using them for Bluetooth music whilst drumming - either to click tracks, drumless music or just my favorite tunes.I find the bass delivery a little bit lacking but as I'm playing drums that really doesn't present a problem for me.Worn non-stop for a good 2-3 hours with no irrotation or problems. That length of times - usage reduced the internal battery to 80% so that seems perfectly acceptable.They look good too. Comes with a small pouch that would accomodate them both easily enough.All in all, a real value for money purchase for an established brand.

Using these for live in-ear monitors when gigging. Really clear and balanced sound with a reasonable degree of noise reduction. They don't have active noise reduction so don't expect it but they provide enough to block cross contamination even with foldback volume low so reduces ears ringing for days after a gig. They do become a little uncomfortable after a while but we tend to play 2 - 2.5 hours without a break which is a long time with any ear buds.
