Excellent fit - awesome sound - noise cancellation is great ... great battery life

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.

These for my tastes are a perfect blend of strong bass, but not muddy bass, and clear mids and highs. The sound personalization is a must to go through. It completely changes the sound and loudness. If you are getting earbuds for music, you should give these a try. Great ANC and Transparency mode as well.

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.

Great sound and noise canceling feature. Fit could be better.

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

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.

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

The Sennheiser Momentum 4 earbuds are top notch. The fit and sound quality are very good. I have had no connection issues. Not the best noise reduction on the market but the best nr earbuds don't have the Sennheiser's sound quality. So a trade off and I didn't expect top tier nr when I made the purchase. The app is fine. I bought the over ear 4's first. Have been happy with those so assumed these would work well for me, too. Haven't been disappointed. I don't know about their durability so will update if I run into any problems down the line.

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.

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)

I would have given it five stars if the left earbud was still work one day it just stopped producing sound the button still work when I touch them to stop or play or rewind music but no sound and everything I've tried has not make it work so I have to send it in but other than that the sound quality is great and the battery lasts about 4 hours of continuous play.

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.

The Sennheiser earbuds continue to improve with each new generation. The sound quality, battery life, noise cancellation, connection and reliability are all amazing and significantly improved over the previous generations. I've given out four of these as gifts over the past year. I prefer them to any apple products, the Devialet Gemini II or the Denon earbuds.

Great service, but it constantly disconnects on my iPhone. Solid performer when it’s connected though. You don’t need the anc due to how well it seals.

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.

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.

I wanted earbuds with excellent connectivity as I move around a lot with the headphones in. These earbuds did not lose any connectivity and the sound quality is exceptional too!

More Full natural sounding notes than the technics az100. The experience close to being in recording booth and not just in the studio
