SennheiserMOMENTUM True Wireless 4 Smart Earbuds with Bluetooth 5.4, Crystal-Clear Sound, Comfortable Design, 30-Hour Battery Life, Adaptive ANC, LE Audio and Auracast - Black Copper

The sound quality is easily better than any other Bluetooth earbuds I have tried. While that's not all that matters in a set of wireless buds, if you are thinking of buying these it's because you prioritize sound quality above all else. It also has a "high end sound tuning" mode which uses a little more battery but is supposed to improve sound quality. I have gotten mixed results, it definitely makes a difference but whether that difference sounds better or worse seems to depend on the type of music you are listening to. With most of my music I prefer the sound without the "high end tuning."They do look very nice (especially in white) and have a good build quality and nice feel to them. They are large but light enough and balanced well enough that they feel secure in my ears. They also have an IPX 4 rating so they are sweat resistant and could deal with getting caught in the rain. I'm not entirely sure about the cloth covered case. It looks and feels nice, but is also difficult to clean and will get dirty if you carry them around with you. I had them less than 2 weeks before someone spilled apple juice on a side table they were sitting on, a side table with a raised edge around it, so the juice just puddled where the case was sitting inside of spilling over the edge of the table and soaked the whole bottom of the case. It was a pain in the a** to clean juice out of and get rid of the discoloration. It's also kind a chunky.The ANC is okay, not the best but as with most earbuds it's only meant for low frequency noise like road noise, engines, trains, planes, etc... Assuming you can get a good seal the passive noise isolation is pretty good on it's own, the sound quality is also very dependent on getting a good seal. It is slightly disappointing that for the price you only get 4 sets of rubber tips, the normal medium tips plus one size larger and two smaller. Unfortunately my ears are slightly asymmetrical inside, so I ended up needing to use two different size tips and one ear usually requires more than one try to get it sitting right. It would have been nice if they included the foam tips from comply that are meant for it. They have included the comply tips with other sets of earbuds they sell, thankfully even though they didn't include them, comply does make tips specifically for these so they fit in the case. I ended up buying them and prefer them to the rubber tips, I think sound quality improved as well (but people seem to get mixed results with that, some saying the foam tips make it sound muffled.) I do have another set of comply foam tips that work better for noise isolation than the ones that are made for these because they are longer, but the downside is you can't close the case with them on.Battery life is not great, it's not bad either and I think it's more than enough for most applications, and the case holds two full charges plus a little extra. They seem to have 7 hours give or take depending on volume and what you're listening to without ANC and 4-5 hours with ANC, which is adequate for most uses other than long jouneys by car, train, or plane, so unless you regularly take long trips and want to be able to use them continuously or are like me and sleep with earbuds in (thin walls and a person in the next room who snores like a freight train and yells in their sleep on an almost nightly basis, plus I have ptsd and sleeping with music or some kind of constant background noise helps distract my mind and prevents/reduces nightmares) and don't like being woken up by a low battery warning, or having the battery die and having to switch to a different set of earbuds/headphones, then the battery life should be more than enough. I usually use my tribit C1's when I sleep, they don't sound anywhere near as good or have ANC and their passive noise isolation isn't as good either but they do have a 12 hour continuous battery life. These have roughly 24 hours of play time including the case (with ANC off) and I cannot think of many circumstances where you would need 24 hours of playtime without being able to get to a charger, save for maybe camping.The app isn't the best, it's a little clunky and the EQ is awful. I do like that you can use the app to switch between paired devices (as long as you connect to your phone first and use the app to switch to the other device) and customize the touch controls. The stock set-up isn't intuitive at all, but it's almost fully customizable, except for volume up/down. You can also turn touch tone on/off and choose between voice or tone notifications, turn ANC, transparent hearing (which works really well, better than any other I have tried,) and high end sound tuning on/off, plus you can turn the earbuds off from the app without putting them in the case (which you can only do from the app, no touch control for on/off.) You also need the app for firmware updates. I like that the firmware can be updated as they fix bugs and stability issues or add features or adjust the tuning. The updates do take a long time though, the last one took 42 minutes, without using them, you can continue to use them while they update, but it takes much longer. The EQ is garbage. No presets and only 3 channels adjusted with either classic sliders or a weird wave form with a dot you can drag around. Why include an EQ if it's going to be awful or useless. It would have been easy to include a more functional effective EQ, sennheiser when asked about it claim it's because you shouldn't need an EQ if the headphones have a neutral tuning that's how the music is supposed to sound... but then why include one at all if they are opposed to them? It just doesn't make a lot of sense. They also have a touch control for whatever the default voice assistant is on the device you are using, which you can assign to any number of taps on either side. These have 6 assignable features/controls and 6 spots, so it's not a matter of choosing which features you want so much as where you want them or you can turn off touch controls completely. They also automatically play/pause when you take one side in or out of your ear, which is a feature you can turn off if you choose. The most recent update appears to have added a feature that automatically answers an incoming call if you take them out of the case and put them in your ears while the call is coming in, as opposed to putting them in and then having to tap to answer, although I haven't tried it yet.People seem to get mixed results with call quality. They work fine for me, no real background hum or white noise, and the mic seems to work alright. It's definitely not the best for call quality, but it works well enough. I usually use my galaxy bud live's for calls unless I happen to get a call while using these or don't have my buds with me.If battery life and really good ANC are really important to you but you still want great sound quality the Sony WF-100XM4's are a great alternative, as long as you don't mind spending a lot more. Even in this price range, an additional $60 is a lot, but the Sony's have a 12 hour battery life to Sennheiser's 7 hours, and better noise canceling. The Sennheiser's I think sound a little better, and in testing have a more accurate neutral sound, but the Sony's aren't far behind and in reality the difference is going to be fairly negligible to most people. Plus the sound quality will vary from set to set and person to person anyway, some sets sound slightly better or worse than others with both models and it's going to depend a lot on which one fits your ear better. The Sony's do come with more choices for tips I believe. The Sony app also has more features, although the Sennheiser's have better touch controls. So if battery life, ANC, and a smoother app with more features are as important as sound quality and you don't mind paying the extra $60 then the Sony's are the best choice, but if it's not worth the extra money and sound quality is your absolute priority then these are the best choice, plus these look and feel nicer and the battery life and ANC are more than adequate.

Look up my reviews by clicking on my name to see my lengthy positive review of the 1st Gen Momentum True Wireless. I loved the MTW1 sound that was full and rich, spacious and refined, but maybe slightly darker sounding. My only concern of the original was the shorter battery life (about like a 4 hr AirPod), and the battery would drain when sitting unused in the case, forcing me to leave them plugged in all the time in order to be ready to use at a moment's notice.I have 2 pairs of 1st Gen, one for my computer and another for on-the-go with my iPhone; because with 1st gen if you went to another room with them in the case and then popped them into my ears they would accidentally connect to the computer in the first room (the last used device). Then I couldn't always get them to connect to my phone that was with me unless you went back to the computer in the other room and manually disconnect from it.With MTW 2 you can go into the Sennheiser app and disconnect or connect to any devices you have paired with, without physically going back to the 1st connected device to disconnect. Jabra 75t can be connected to 2 devices at the same time, which would be nice to have here (watch movie on PC, answer call on phone).With the MTW 2 the battery doesn't drain when in standby while in the case anymore, and now I don't pick them up after being unused for a while to find the battery flat. Although I haven't tested the 7hr battery life claim from full to dead, they outlast my 1st gen for sure. I can only tolerate universal fit in ear monitors for about 4-5 hours at a time, as my ear canals feel itchy from the silicon tips (I prefer to use custom molded acrylic earpieces). When I need to use a true wireless all day long, I have to use my Powerbeats Pro which rest at the opening of my ear canal instead of sealing inside the canal.The transparency mode isn't too quiet anymore, so I feel safer when walking down the street with these in my ears - it's almost as good as Apple AirPods Pro transparency, but not quite, as it is slightly more "hissy" in transparency mode than Apple. The transparency mode sounds that are filtering in aren't tinny sounding like Samsung GBuds+ or Jabra 75t, but rather it lets full frequency sound through. And, with passive mode or with ANC on there is no hiss.The Sennheiser ANC mode is an appreciated addition vs the 1st Gen, again not quite as good as AirPods Pro or Sony WF1000-XM3, but it does help a lot with fans and running water or car engines. It's maybe as good as Master and Dynamic MW07 Plus ANC or slightly better. If my ear canal size wasn't somewhere in-between medium and large silicone tips, I guess I'd have a better seal and better ANC performance.Sound quality beats the AirPods Pro again with more realistic timbre and tone than Apple; and it also adds more detail and clarity vs the 1st Gen Momentum TW, without losing the open and spacious soundstage of the 1st Gen. Sometimes I turn up the bass in the Sennheiser app just a little for quiet listening, and it remembers those settings when I switch to using them with my MacBook - the Sennheiser BT LE app will let you control the EQ and settings from your iPhone while listening with your MacBook, if you need to make changes.But I am perfectly happy with the Momentum True Wireless 2 with no EQ as well, just like my original 1st Gen MTW that sounded a little darker without EQ. The Jabra and Sony can be EQ'd via their app to make them sound closer to the Sennheiser, unlike the GBuds+ (horrible in-app EQ) or AirPods Pro (no EQ). My Master and Dynamic MW07 Plus have a U-shaped frequency response and no app to EQ at all, so Sennheiser wins there. However, the EQ'd Sony XM3 doesn't sound as spacious and open as the Sennheiser.EQ'ing via the Sennheiser app doesn't introduce any distortion that I have noticed, and you can use two different interfaces to EQ the sound, depending on which way is easier for you - a single slider to get a curve, or 3 sliders for bass, mids, treble. I'd like to see a 10 band EQ, but there aren't enough flaws in the sound to need that fine of tuning.The programable features available in the app are much more complete than with the Gen 1 MTW. I can choose how I want taps and press-to-hold to work, but out of the box the settings are good. Now I can get "play" with a single tap on the left side and "Siri" with a single tap on the right side. Same with Transparency and ANC mode vs skip forward and back, where each side is doing something different - I can double tap on the right to go into transparency and triple tap do ANC, but I have the left side do skip forward and back with double and triple taps. Press and hold left is volume down, and on the right it's volume up. That's 4 functions per side, 8 total, and nothing is missing. Some of my ear buds can only do 6 functions with taps/press due to duplication of a tap on both sides, and so I can't control volume or some other feature.Overall, the Momentum True Wireless 2 are a great option for music and phone calls, having added sidetone (your voice) when on a phone call, which Momentum TW 1st Gen doesn't have. These have improved battery life, great sound (via AAC, SBC, or Aptx), and a lot of features of which you are in control.Now my main complaint is that while the charging case is slightly smaller it's not as small as I'd like for keeping in a front pants pocket vs the inferior sounding Jabra 75t, Samsung GBuds+, or the AirPods Pro. And of course, I miss the Qi charging of the Galaxy Buds+ and AirPods Pro. If Apple and Samsung can squeeze that into a smaller case, Sennheiser should have tried too, especially at this price point.
