Customer Ratings & Reviews

If you liked the sound from the 3s then youll be happy with these. They are basically the same. But i cant help to wish for more. Bigger drivers? Louder sound? Better switching from one device to another? All of the above! Sound is crisp and clear but wanted more.

Excellent sound quality and fit. Support for dope codecs

Having used so many different earbuds these really dont do much to stand outside the norm i feel the price is a bit too much for what you get overall i do t regret buying these but im most likely gonna buy something else

The sound quality and app features make these an excellent choice for any audiophile out there.

Audiophile sound, confortable fit, decent noise cancellation...fair price.

I've been using the MTW 4 earbuds for about a week now. There is a deal-breaking bud that I can't accept. The buds auto-reconnect to my phone when placed back into the case. Every single time. I realize the buds just got released, but come on. If any product has issues out of the box I return it. I'm not keeping the product hoping for a fix. I previously had the MTW 3 and feel these took a step back in sound quality. The MTW 4 don't sound as full to me, with bass really lacking in comparison. I'm sure Sennheiser will release several firmware updates which will improve the sound. But again, for $300 I'm not keeping a product hoping for a fix / update. There are much better options out there if you want to spend a bit more. At $300 at time of purchase, the value isn't quite there. For $50-$100 more you get into a totally different tier of earbuds, such as Denon or Devialet. Both are far superior and blow almost every other brand of earbud out of the water.

These were almost perfect. The sound was great, and the overall fit was pretty decent. There's just something about these that just.. lacked. Pretty heavy ear fatigue after about an hour or so. Call quality was eh, and they cut in and out a lot according to the folks I talked to. I dont think theyre worth the price tag, and they have a lot of bugs to get worked out. Maybe one day itll be a hit, but for now ill save my money.

These headphones sound amazing, with quality sound. Although the anc isnt as good as competitors however i wasnt looming for that.

Sound quality, excellent for running, quick connect

These sound extremely good. Very super clear and crisp. Easy to set up. Good enough price. Better then the bose!

Fit needs improvement, case is too larger. Ok sound quality but you gotta drill it into the ear to get the best sound possible.

They sound good and have an amazing style. However when I bought them they were not working properly. They ended up having an update that fixed the problem later.

I bought this pair to replace a my old pair that was exactly the same, and these are somehow better than the last.

Good sound quality, the Podcast mode makes everything sound more crisp in sound. Not the best for call quality but ANC is good.

One of the best earbuds when it comes to sound quality. Not fitting well on people with small ears. You have to keep adjusting it when walking or running.

You can watch some pretty detailed reviews about these. I already own XM5s and those outshine in my opinion. If you own an Android phone, you will have the ability to fine tune the sound. With iPhone, those adjustmets will be more limited. I think if I could better adjust the sound profile, I would have considered keeping these. Sound is really subjective and if you’re on the fence, try these out. For me, the Sony’s have it all out of the box for the same price.

Love them! Awesome sound quality! Fits perfect in my ear

Really good headphones but the warranty is only 12 months and the left one stopped working after using them for 14 months.

Super clear, strong bass. Very clean sound best earbuds I've ever had. I've tried just about every brand these are#1

They are awesome Earbuds but I just can't give 5-*****'s to something which I feel are overpriced. (make sure you use the sound optimizer feature for the best sound)
