Sennheiser - MOMENTUM True Wireless 4 Smart Earbuds - Gold

4.5 stars if I could. Having previously owned the gen1 Momentums, these have come a long way and I'm overall pleased with them. Only one big gripe which I'll detail. Sound: I personally find these worthy of the Sennheiser name. They probably won't knock your socks off like some high-end IEMs but the sound is solid with sparkling highs, clear mids, and satisfying bass. Everything comes through. The in-app EQ has also come a long way in allowing you to really tailor sound to your preference. Noise Cancelling: This is decent. I think the silicone ear-tips kinda work against them in the noise cancelling performance however. I really prefer the foam tips that I previously had on my Sony xm4s which did a little better at blocking out train noise and chatter around me. Battery: No complaints here. Battery life seems as advertised. Only time will tell if the batteries in these last for more than a couple years though. (unlike my Sony xm4s) The app features an optional battery health mode which restricts the case and buds to charging up to 80-90% respectively. Charging all the way to 100% will cause the most wear on your batteries so I appreciate this feature. Fit/Comfort: These fit my ears just fine but again I find myself missing the foam eartips I previously had. Sennheiser has added an additional size of tips as well as different wing shapes that can help stabilize the bud in your ear but I never have issues with them falling out. They're comfortable enough to wear for a few hours. Case: Wireless charging is greatly appreciated and it looks pretty with the fabric. However, I'm quite frustrated with the dimensions. I can't believe they are now on gen4 and still have this case that is way too thick. It's like packing a sizeable rock around in your pocket and gets annoying as soon as you want to walk anywhere. They slightly shrunk the case length-wise but that's the only difference between this and the gen1. The charging port also shouldn't have been moved to the front. I find myself trying to open them on the wrong side now because it more closely resembles the hinged side if I'm not looking closely. Quite annoyed with the case overall which is mainly what keeps these from being a 5/5 for me. App: It's decent. No issues with connectivity so far and I like the EQ and battery life settings. I use the buds with a Pixel 7 and they pair quickly with no skipping.

After about a month or two of owning these wireless earbuds from Sennheiser. I’ve realized something… I will never buy another pair of wireless earbuds that aren’t hifi audiophile grade. The sound quality paired with the amazing wind and noise reduction, easy transparency mode switching. Audiophile geared tuning and app control. All ties together when you realize you can rock these earbuds for around 20 hours without charging the case. And even then, I just throw it on my wireless charger! If you charge them on your wireless charging mat passively, it’s an easy way to assure you never are worried about not having that crispy sound in your ears. Thanks Sennheiser! Truly, you can tell German craftsmanship apart from the herd. Just look at the frequency response!

These are by far the best sounding wireless ear buds that Ive experienced thus far. These give details that I had previously missed in ny past years of streaming. Granted, most of my streaming experience has been using apple products... The stage is in your head with the TW4, and the layering is close though you can still hear the separation and quality of detail. They arent the most comfortable which kind of steps on the experience as after a few hours youll want to take a break. I would have been able to survive with that, though the reason I'm returning them is due to the intermittent connectivity issues especially when using both earbuds. I usually have one in while driving or working and will experience no issues as it's usually audible/youtube/podcast while driving and music while working. Though once i get home and want the personal immersion of quality music the right earbud is the culprit to either crackle or completely cut out the streaming but remains responsive to touch input. I notice that its usually when the codec is switching between aptx adaptive and "lossless." I know that hi-res can be unstable or unreliable with bluetooth, but I wonder if these would have more stability if they were using LDAC over aptx. The sound is worth the premium, but the connectivity issues kind of negate that. Im using a Motorola Razr ultra 60 at the time of this review (just incase time reveals that the issue maybe phone BT connectivity). Overall, they bring music to life... When they work.
