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

Sturdy. Use them for walking. Good sound. Worth the price. Buy cheap buy twice.

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.

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.

Really great sound quality and the flexible hook means you can adjust them to comfortably fit your ears.

Disappointed with these buds, got these as a stopgap before I bought some Bose ones to replace ones I had previously - no real sound level to them and disappointed with overall sound reproduction.

Performs overall equal to a 20-30GBP wireless headphones.The premium cost compared to cheaper alternatives is not justified.Note: I did not test the call/phone qualityPro's- Decent sound quality.- Good build.- Fit and wear are good (does take some practise on putting them in).- USB C charging.Con's- Disappointing battery life compared to cheaper alternatives.- "Low battery" voice warning is ~1 min before the battery is fully empty. Sort of defeats the point.- "Disconnected" voice message is annoying: When I turn on the headset it connects to my phone just fine.But when leaving the house (connected to my phone) the headset starts to warn me every 30 seconds that it's disconnected (presumably from my laptop as this is now out of range) and the warnings don't stop.Maybe this is a feature for musicians to warn them they disconnected from one of their sources.But for my daily commute use this is annoying. As I have to power cycle the headset to stop the message- Buttons are placed weirdly and somewhat hard to use- The two in-wire units are somewhat unbalanced (weight wise) so the wire pulls constantly to the left.
