Customer Ratings & Reviews

Very comfortable with an excellent sound. With all of the high end options on, they only last about 4 hours before having to put them back in the case but all in all an excellent product and definitely the best earbuds I've bought

These headphones are wonderful to wear! They have great sound and awsome responsiveness to touch and configuration. They will slide out after a long time; all in-ear headphones will.

These earbuds have excellent noise cancellation. The sound quality it top notch. I listen to lots of classical music and these earbuds seem to capture every frequency. The equalizer within the app is a great touch. The price is low compared to all the professional sounding audio you will get from these earbuds.

Top tier earbuds, especially once you fine-tune the sound profile. For audiophiles who prioritize amazing detail, clarity and depth. I've owned other high end buds such as the Sony XM4 and XM5, and the Momentum 4s sound superior, and ANC is on par. Galaxy buds and AirPods aren't worth mentioning since they aren't even in the same league as far as sound quality.

Sound quality with these earbuds is quite insane. Coming over from a reputable brand user of 10 years is a night and day difference. The sound cancellation is unreal and makes everything personalized. The only reason these are 4/5 stars is due the microphone not having any noise cancellation which makes phone calls a big 50/50.

I upgraded from the Sennheiser Momentum True Wireless 2 and it’s worth it! The sound quality is superb and I notice even more sounds than with the MTW 2. The fit feels more secure and comfortable to wear throughout the day as well. If you’re looking for an upgrade? These are one of the best options out there.

Excellent product from Sennheiser, as expected. The only flaw is the midrange and treble are recessed a little. Great bass and sound overall, with detail and high resolution

Good item love the sound and its very comfortable. Only issue i had was i got a lemon and needed it replaced. Happens sometimes but no reason to knock it down a star.

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.

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

Fantastic earbuds! Very good low end bass, Surprised at how dynamic these are. Especially once you mess with the EQ a bit. I don't think these get the credit they deserve! Sennheiser for the win! Side note: if you wear them while working out, try out the bigger fins that they come with (unless you have tiny ears)

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.

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.

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.

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

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

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 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.

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 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.
