My AZ80s battery went bad. Got these to try the out. Since the AZ100s weren't avaliable at the time. Sound is good but the interface was terrible for me. Most of the time i wear at work have one bud in. But to have the 2nd bud connect i have to put back in case and take both out. When my AZ80s and now my AZ100s i dont have to that.

Im going to keep this review pretty short and simple. These headphones are some of, if not, the best wireless headphones on the market. Anc is clean. The soundstage is perfect. Battery life is excellent. They are my everyday carry for the construction world and they hold up. I highly recommend.

I have a pair of MOMENTUM 23 that I have used heavily, and battery runtime was becoming an issue, so I bought a pair of MOMENTUM 4 to sit on my wireless charger and always be available to use. The 4's background sound is clearer and they fit more snugly. They seem to connect faster.

Fit perfect rifht out of the box. Sound quality far exceeded that of my Samsung Galaxy Pro buds. Bass response is fantastic. The app is intuitive and easy to use. I highly recommend thhem.

I bought these for the musical sound I heard about them and they didn't disappoint. The call quality is good too. I like the custom sound aspect. It allows you to dial in the bass/treble for the perfect sound.

Require a bit of tinkering with to get the best out of them. Make sure you play around with the ear fins for the best fit. App could be better but once tuned it's great.

Sennheiser is a well known and reputable brand. Their products are known for high quality sound, durability, and reliable performance, and they are widely used by both professionals and everyday users.

Headphones have been nothing but stellar. The sound is great, the case has a nice feel and the magnets pull them in smoothly. Full bass sound from such small speakers.

Love how they work in various environments. Especially at the airport or even in the airplane. You’re able to cancel noise very well while listening you one’s content and even hear airport alerts.

Does exactly what they are intended to do. Great sound, more than acceptable ANC, wireless charging case, multi point connection. Slightly uncomfortable, but most in ear buds are to me. Great product.

I mean its Sennheiser sound quality. Never disappointed me in that regard. It has a lot of issues for me. The most important one is noise cancelling. It says its active nc but I highly doubt it. In an office environment, when these are on, even while I am playing some binaural beats, I can hear even the chair squeaks of my colleagues when they just move about. I can hear everything they are saying. When I turn off the noise cancelling, it channels more noise in which is fine but there is no just off button. The reason I even looked for "normal" state is because when you turn on the noise cancelling, you get to hear this faint hissing sound that is base-e. I guess thats all the noise cancelling it does. That base heavy hissing sound cancels out the noise from things like if you have a fan near by or you are in an airplane but you still hear everything else. The second issue is the connection. I never experienced it to just connect and start playing. I always have to give it like 20 seconds for it to settle down after connecting to a device whether a laptop or my cellphone. After connecting, the sound randomly cuts off in one ear, then it comes back and then the other ear is off and so on until it settles. Then it is fine. The comfort is another issue for me. Yes it does give you lots of options to customize it but in some configurations you loose the base when you gain comfort. That's not much of an improvement is it? I have to sacrifice sound quality for comfort? At this price point? As I am typing this review, I hear every key click from my keyboard. How is this a noise cancelling headphone? Wow my friend just walked by my desk and I heard the smacking noise from his flip flops and I am playing binaural beats with heavy base right now.

Wish the eq was more detailed like with the previous model other then that they sound amazing

These earbuds are amazing, sound quality is nice and it does feel like you’re using headphones, I do recommend tying them first before buying them because of the sizes but you can change them too

My go to earbuds for the gym and flying. The active noise cancellation does its job, as well as the transparency mode. The sound on this earbuds is amazing and being able to customize the sound is plus.

Pretty great the sound is amazing. My only gripe is that the function it uses for Bluetooth pairing is kinda buggy if you pair it to more than one device the earbuds won’t know which to connect too and will keep bouncing back and forth between devices unless you turn one devices Bluetooth off.

I got these for my husband, and he uses them everyday! We also have AirPods and he likes these better. Sound quality is perfect and the noise cancellation is amazing. Connectivity is great.

Very quality, definitely worth the sale price. I might prefer the technics-az80 a little, but I’m not an audiophile. Still great sounding earbuds and a comfortable fit.

When it comes to having some of the best sound around this is definitely it, build of device is also very premium. Great pair of earbuds but maybe not the most comfortable or for running

Sound quality is very good. EQ is alright, it didnt make enough of a change to consider having my own custom mode. The app is nice but the real highlight is the sound quality. Balanced and loud sound. Deep bass without being overpowering.

Amazing sound and great quality. Worth buying in my opinion.
