Great sound quality, and awesome customisation for fit in you ear

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!

[Employee of bestbuy] These are my go-to earbuds while I’m out and about. The app is easy to use and you are able to fine tune them to your liking. I also ride a motorcycle, and there is a mode to reduce wind noise which I like. I have 14 pairs of high-end headphones, and I use these the most.

Great connectivity with bluetooth and excellent sound!

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.

Pleasantly surprised how much these buds can take i use em all day for work and gym and still have quite a bit of battery left wished they were a bit more comfortable in staying in my ears but pretty good buds overall

Much longer batterlife before having to charge it. Comfort in wearing long periods of time.

Excellent sound quality and fit. Support for dope codecs

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

These earbuds have great sound with the dual type duel drivers. The sounds punch out at you however, the noise cancellation is poor.

Sound great and look really cool. I love the bronze color.

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.

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.

A little to much bass out of the box. Phone App work for basic without an account (eq, firmware up dates, notice canceling) . App will not sign to use all the extra stuff.

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

Amazing earbuds. Great sound and very comfortable. The battery life is almost eternal!!

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.

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)
