Excellent all round, highly recommended.
I purchased these over a year ago after going through a phase of using cheaper brands of earbuds, which all became faulty pretty quickly, I splurged on these and they are really excellent. The stability of the fit is superb thanks to the innovative little fin at the top. The sound quality is very good, not audiophile but nearly there, not too bassy. Excellent all round, highly recommended.

Could be my Best Headphones so Far? 🏆🏆🏆
Ive had so many headphones over the years. Ive always looked for "Good Sound" and durable. The 1st thing i noticed was the "Frequency Response". These Bad Boys go 5Hz to 20000Hz which i think is rare. On my search for headphones it seems most headphones only go as low as 40Hz, with other brands, which is "OK", but for real bass heads you want that boom in your headphones look no further. They are comfortable once you find the Fitting for your ears. they didnt hurt and i could wear them for Hours. Ive also seen people say "Its Not Loud enough". IMO the level is fine. its loud enough to hear all the detail in the music u are listing too without distortion. It also comes with a really good durable case. Battery is great too. Ive seen mixed reviews but i gotta say Senheiser for QUALITY, GOOD PRICE have a real good product here. If ur a Jogger, Gym head, Walker, traveler i think u will like these. Good Purchase, u wont be disappointed 🏆🏆🏆 👌

Left earbud breaks after 4 months
Don't bother buying these. I bought a pair in June 2024. They sounded great but after 4 months the left earbud just died. There was no physical damage, it was fully charged - but it stopped working completely. I returned the pair to Sennheiser and they said it couldn't be repaired and sent me a replacement. Fine - until, another 4 months later, the left earbud of the replacement pair stopped working in exactly the same way. Clearly there is a design fault as it's too much of a coincidence for exactly the same problem to affect two different pairs in such a short timeframe. I'm currently trying to get a refund from Sennheiser because what's the point of getting them replaced again, but they have refused as I didn't buy it directly from them. So I've contacted Amazon and they say I have to get the earbuds back from Sennheiser, then send them off to the Amazon service centre to be checked before they will refund them. So much hassle and meanwhile I am still without a working, reliable pair of earbuds.

Amazing battery life and quality sound
To start off with most aspects of this product are very good, the sound quality is excellent with crisp highs good mids and deep lows, no muddled bass, the volume isn’t as loud as AirPods for example but it’s high enough to deliver loud music without hurting your ears, with no distortion on high volumes. The battery life is absurdly long, I charge these once every 3 weeks and even then the charge has never dipped below 25%, with daily use during commutes on high volume. Fitment is good with 3 different sizes of tips to use, it’s important to experiment with these as I found the medium tips can cause pain for my ears, whereas the large size fits better and causes no pain or discomfort with long wear time, I settled on using a medium tip on one and a large tip on the other because apparently my ears are a little different. Noise cancellation on these is good enough for me personally, I use them in busy town centers and have no problems whatsoever, and the transparency feature while in a call or activating Siri can be very useful to hear what people are saying. Sometimes the left side will not connect, this has happened once in the 2 months I’ve been using them, with a simple solution of placing both buds in the case, holding them both down with fingers for 40 seconds, and then using them, this fixed the issue immediately, this occurs because the right bud connects to the phone and the left bud, and sometimes the right cannot connect to the left. They are a little large, but don’t look obnoxious or strange at all while In the ears, I would prefer a smaller case or perhaps a more flat case, as the rectangular shape of the case can make it awkward to store in pockets. Overall I am very pleased with the product, with very minimal issues during use, and a good rich sound with long lasting battery.

Great set of earbuds
I’ve only had these for a week or so, and I’m aware that some people have reported faults after a couple of weeks, so I may have to update. So far though, I’m really happy. Great sound, no problems with connection (was in the French Alps) Wonderful selection of in ear buds sizes and wings I have the app already for my big headphones (momentum 3), so set up was straight forward. Apple phone. Charging through the holder and in holder during the day all good Look: the look great, but who is looking in my ears! Weight: very light.

Perfect for the gym, but design-limited short life expectancy
I'm editing this review because I've just been informed of something by Senhheiser, after contacting them about an issue I had with the earbuds. It seems that the earbuds do not power off if not put back into the charging case, leading them to discharge over a few days even if not used (not even connected to anything; the phone was turned off). Why is this an issue...? Because keeping them in the charging case keeps the lithium cells 100% charged. That is absolutely terrible for their life span and *will* make them fail earlier. If I could keep them out of the case and only recharge (preferably not fully) when needed, I could do that once a week at most with my use and the cells would probably live twice as long. That stuff is pretty much common knowledge now. With this design, the earbuds will die in half the time they otherwise might. I'm very unimpressed with that. Original review: Sitting on a rowing machine for an hour is boring. With these comfortable earbuds, I can enjoy that hour instead of wishing it was over. The earbuds appear of good quality and the fit into the ear is well designed. There is no slip at all with the right-sized hook selected. So far I've used them for a two weeks after a full charge, training every day and deliberately not recharging them to test the battery out. I've still not had a low warning (I'll charge them now though - don't want to run them down too far). They've survived sweat and rapid rowing without a hint of loosening and are proving durable and very good value. Sound quality is excellent for the price (I'm comparing with my main headphones that cost £600).

Amazing headphones
These are an amazing set. So good that when I lost my first pair, I did some research to see if there was anything better at this price to features and I couldn't. Struggled to find something that would sit securely and be comfortable for long dog walks and gym workouts. They sit well in my ears right out of the box. The sound is bass heavy with clarity over the whole frequency range which I love. There's no sound cancelling but I don't notice due to the secure fit in my ears. Touch controls work every time (even with thin gloves on) with volume easy to adjust without the need to get the phone out. Only grumble with them is the case is bulky as it's like a cube. So yeah, there amazing

A major flaw!
Used these for a good 6 months now, coming from a pair of Bose headphones. Pros: - Battery life is great, used them for a marathon so about 5 hrs out the case. The charge from the case is great so don’t really need to charge regularly. - The fit of the buds once you get the right ones is great, no movement when they are in your ears. - Sound is not bad, can get a bit boomy every so often (mainly listen to dance music) Cons - a major one for me… the touch control! Bearing in mind these are sports headphones they do not recognise the amount of presses, is very sporadic! Top tip if you do buy a pair, turn off the volume increase in the app, otherwise when you think you have asked to change track it will suddenly increase the volume and deafen you! Most of the time if you have even a little bit of moisture on your hands it will not recognise and bleep at you! - They are comfortable for running in even for a marathon but when I’ve used them on a plane or not moving I find them slightly uncomfortable after an hour or so
