I just received these Sennheiser Momentum 4 cans about 7 days ago. I bought them for $270, and now I see you can get them $20 less. I made the purchase, despite the negative reviews posted on Amazon simply because I have learned that reviews don't tell the whole story. Such as often times when it comes to Bluetooth devices, there will be a new firware/update that will need to be done, depending on how old the product is. In my case, that was the case. The firmware update was easy, took maybe a minute or two, and I was off and running. I have owned, and sold several headsets, from JBL, Beats, SkullCandy, Sony and yes, Bose. Now, for me, and how I like my music to sound, the Sennheiser 4s are by far the best sounding Bluetooth headphone to grace my melon. Mids, highs and lows work amazingly well. Wind and string instruments sound crisp, and suppurb! The lows/bass work harmoniously with the above mentioned. The Sennheiser equalizer is easy to use, and gets the job done. Touch controls: they take getting used to, but, once you adapt, it works great. Yes, at times you may pause music when touching the right ear cup, but again, you will adapt and recover. Comfort. These cans are extremely comfortable. Even for my large head. Ear cushions are comfy, as is the head cushion. Could it use more cushion? Maybe if you wear them for 8 hrs straight. Weight. Yes, they way a tad bit more than the competition, but, that is to be expected as the battery is slightly larger...hence why you can get up to 60hrs of life on these bad boys! The cans don't feel cheap, they feel solid. And that is something I can appreciate. Are these cans perfect? They are as close to perfect that you will get (IMHO) on Bluetooth headsets. Are there better cans out there? Sure, If you go wired, and spend a few hundred more, then yes. Even Sennheiser wired headsets (depending what model you get) are better, but that's because they are wired. Of course they will sound better. One thing I didn't discuss is noise canceling. They get the job done in fine fashion. I have tried the Sony 5s, and they are slightly better than the Senn 4s. I have made several phones calls, FaceTime calls and the voice activation works wonderfully! I am 7000+ miles away from home, and not one complaint on how I sound, or, how the other end sounds. Lastly, battery life. It claims you can get 60hrs of life once fully charged. That is a fact, as I have tested that claim and 59+ hours the first charge, not quite there for the second charge. Mind you, it will lose an hour or two depending on what you have activated. Accessories. Well, you can listen to these cans wired, especially if you run out of charge. You will need a dongle (I purchased one from Amazon) and they sound great. It will sound different, and you may need to adjust you equalizer. The case the cans come with is a solid, good quality case with charging type C cable, 3.5 wired jack, and an airplane adaptor to plug your cable into so you can listen to movies or music that the plane is playing. And it all is neatly stored within the case. Final thoughts: I honestly feel that alot of the issues that some people reviewed on Amazon is these headsets have "buggy" issues, or connectivity issues. Perhaps some just don't know how to do firmware updates, the phone they are using is dated? Not sure, all I know is mine cans fired right up, and I did the update straight away. These cans have Bluetooth 5.2, so it should be able to connect to any device that's out there currently. Yes, touch panel does take some getting used to. Much like driving a truck, then driving a sport car. It may take a moment to get familiar with the vehicle, but once you do, it's a piece of cake. I decided to take a chance, I did my research outside of Amazon reviews, and watched the pros on YouTube, and that's how I ended up buying these. Big risk considering I am a world away. Give em a try, you can always return them if they aren't for you.

I upgraded from a Momentum 3 with a Creative BT-W3 dongle for atpX Low Latency. I upgraded to the Momentum 4 with an Avantree DG60P dongle for aptX Adaptive in low latency mode. This allows for PC gaming on Windows with great audio quality and no perceptible latency. I am extremely happy with the upgrade. (Note: though it supports aptX Adaptive, Sennheiser's own BTD600 dongle is not well suited for gaming, due to its high latency.) Comfort: Comfort was my main reason for upgrading from the Momentum 3. It's very satisfactory on the M4. It's better than the Sony XM5, and far better than the M3, but many say that the Bose QC Ultra is better. I've only briefly tested the Ultra, but this seems right to me. The headbands on the M3 and XM5 both get quite uncomfortable after a few hours. Design: The black and copper design has been my favorite of any headphones I've owned so far, even worth the extra $30 to me. The case is also sleek and feels premium. Sennheiser has taken a more "boring" modern design this generation but the result outclasses the XM5 and QC Ultra in my personal opinion. Sound: The sound quality is a noticeable step up from the M3, and the M4 is my favorite sound signature compared to the current generation's Sony XM5 and Bose QuietComfort Ultra. The EQ is highly customizable in the app. Sennheiser is famous for its audio for a reason. Companion App: Easy to use and convenient for managing your connected devices / checking codecs. You can even see the codec being used when playing audio from a different device. The Sony app has more features and is generally better. Both apps are simple and functional, which I like. The Bose app is a pain every time I have to use it: failing to identify devices, failing firmware updates and necessitating factory resets, forcing between ANC/transparency with no "off" setting, and having the least useful equalizer of the three apps. Touch Controls: A big upgrade over the tiny buttons on the M3. They feel on par with the touch controls on the XM5. Gestures: Unfortunately the controls are not customizable, but they are simple and do everything I need. The XM5 has more useful gestures/features, such as cupping your hand for temporary transparency, or activating transparency by speaking. Active Noise Cancellation: it's pretty good, definitely better than the M3. But today's XM5 and Bose QC Ultra do better. Its intensity is customizable via the app. Transparent Hearing: It's loud & clear, but doesn't sound very natural. It sounds more like a recording. Also customizable in the app. I think the XM5 does this better. I haven't tested the QC Ultra on this. The auto-on / auto-off feature is extremely convenient. By putting the M4s in the case, it will automatically turn off. Taking them out of the case will automatically turn them back on. This is equivalent to the M3s, which would turn on by unfolding them. Multipoint makes for a pleasingly simple experience. I don't have to spend time pressing buttons to turn the device on/off or pair. I just put the headphones on and start playing audio from either my PC or phone. I haven't tested the battery life, but it dominates the market right now at ~60hrs. Not so useful for my situation but great for travel. Conclusion: All-around fantastic headphones with many strengths and no major weaknesses. If you care about design, wireless PC gaming, battery life, or sound quality, the Momentum 4 is a clear winner coming in at a lower price. Depending on your situation, you may be better off with the Sony XM5 (for features/ANC) or the Bose QuietComfort Ultra (for comfort/ANC).

I bought these after craving some better sound quality from my personal pair of headphones. I upgraded from the Bose NC 700's. These were a big upgrade in the sound quality department. Comfort is fine, but Bose headphones are slightly lighter and much more comfortable over all. Bose headphones definitely have better ANC without a doubt. The build is sleek, attractive, and light weight. I got these on sale for $250. Amazing bargain and easy choice over its competitors such as Bose and Sony that cost more at the time. I have listened to all the new headphones such as the Ultra QC, and 1000XM5. Sound quality wise, the momentum 4's are better. The negatives: The only reason I didn't give these headphones a full 5 stars is because they are sooo buggy. I have had issues pairing with my mobile device, issues with the touch controls not working at all or only intermittently working, sound randomly cutting out at random intervals for about a second. They all have their pros and cons, if you are like me and you only care about sound quality, these are it.

I'm usually only an earbud guy. I've always considered myself a high end audio enthusiast, but not an audiophile. I like good sound and a great sound stage. These are my favorite to listen on. They last forever, they sound great with a balanced sound profile with decent bass. I'm not an electronic music listener. They handle rock, blues, metal, and folk with ease. I listen to movies on them and they do amazingly. The ANC is incredible. If my son is playing Xbox while I'm on my ipad or laptop in the same room I just turn the ANC on and I cannot hear anything but my audio source. The sound reproduction does miss some subtilties that I hear on my Momentum 3 true wireless or my Sony WF 10000 mk5. Which is a bit odd. It just changes the sound of the snare hit ever so slightly and sounds a bit more compressed. That is my only nitpick and only in 2 or 3 songs that I've noticed.

Além da qualidade de som incrível, o cancelamento de ruído é muito bom! Fizemos muitas pesquisas antes, esse é para uso diário do meu marido, e já tínhamos outros 2 Bose (NC700 e outro QC45) então já conhecíamos a qualidade deles, mas esse surpreendeu, inclusive no quesito cancelamento de ruído, é melhor que o NC700 (todas as pesquisas diziam que a Bose se destacava). O encaixe na orelha dele é perfeito, abraça as orelhas e no machuca, permitindo o uso mais prolongado. (Bose NC700 costuma machucar quando uso óculos, isso não acontece no Momentum 4) Depois adquirimos um Bose QC45 Ultra, e nesse caso o cancelamento de ruído da Bose ganhou, mas em conforto de longos períodos, Sennheiser é melhor!

(Español/English) Español Calidad de materiales: Sí, son unos audífonos que se sienten muy premium; las almohadillas, los cables, el estuche, todo es perfecto. Batería: Creo que las 60 horas anunciadas son un buen estimado. Podrías necesitar cargarlos al 100% una vez por semana bajo uso continuo, lo cual duplica la duración de cualquiera de mis otros audífonos (WH-1000XM5, QC-35 II). Comodidad: Los pondría al nivel de los WH-1000XM5. Son bastante cómodos, pero tengo las orejas grandes y una parte de ellas no queda cubierta por las almohadillas, lo que puede ser algo incómodo después de varias horas, además de que no sellan completamente el ruido exterior. Características: La aplicación tiene muchas opciones, aunque todo se presenta de manera bastante desordenada. Creo que lo mejor es simplemente hacer el emparejamiento inicial con la app y dejar los ajustes por defecto. El apagado y encendido automáticos se sienten como magia; no es necesario apagar los audífonos presionando un botón por varios segundos. Simplemente te los quitas o te los pones, y se apagan o encienden de forma muy natural. Lleva un poco de tiempo acostumbrarse a los controles táctiles, pero son muy responsivos y es divertido aprender a usarlos. Conectividad y calidad de sonido: Como cualquier par de audífonos inalámbricos modernos, utilizan Bluetooth 5.0 o superior. Se obtiene buena calidad de audio al usarlo con un celular, y cuando se conecta a una computadora, se muestra como dos dispositivos: uno es la salida de audio estéreo y el otro es un dispositivo manos libres. Estos audífonos tienen la característica de poder conectarse directamente a una computadora con un cable USB-C y usarse mientras se cargan. Sin embargo, en ningún lado he visto que se explique lo siguiente: Cuando estos audífonos se usan por Bluetooth y únicamente se reproduce multimedia, la calidad de la salida estéreo será como máximo: 2 canales, 16 bits, 44100 Hz (Calidad de CD), lo cual proporciona una experiencia de sonido promedio; no es mala, pero tampoco es destacada. Si estos audífonos se utilizan para reproducción y grabación al mismo tiempo, por ejemplo, al jugar a un juego en línea con chat de voz, los audífonos pasarán al modo manos libres y la máxima calidad será la siguiente: Reproducción y Grabación: 1 canal, 16 bits, 16000 Hz (Calidad de grabadora de cintas) La persona del otro lado no tendrá problemas para escuchar tu voz, ya que el micrófono hace un buen trabajo aislando el ruido ambiental, pero la calidad de reproducción es horrible. Entonces, si tenías la esperanza de utilizar estos audífonos para streaming, por ejemplo, busca otra opción o usa un micrófono aparte. Dicho de otro modo, estos audífonos no pueden reproducir audio de alta calidad y grabar desde el micrófono al mismo tiempo, ni por Bluetooth ni alámbricamente. Finalmente, tenemos el modo alámbrico con cable USB-C, donde de verdad se escucha la diferencia en la calidad de sonido, siendo la máxima calidad disponible: 2 canales, 16 bits, 48000 Hz (Calidad de DVD) Y debo decir que la calidad de sonido es superior a la de mis Sony WH-1000XM5 y Bose QC-35 II, sin lugar a dudas. Le doy 5 estrellas por la calidad de sonido en modo alámbrico y la duración de la batería. English: Build quality: Yes, these are premium headphones. The headpads, cables, and travel case are simply perfect. Battery: I think the advertised 60-hour duration is accurate. You might need to fully charge the headphones maybe once a week with continuous use. This easily doubles the battery life of any of my other headphones (WH-1000XM5, QC-35 II). Comfort: I would say these are on par with the WH-1000XM5 in terms of comfort. They are quite comfortable, but I have big ears, and part of them isn't fully covered by the pads, which can become uncomfortable after several hours. For the same reason, the pads don't completely seal out external noise. Features: The app offers a ton of options, but everything is really disorganized. I believe it's best to simply go with the initial pairing and leave the defaults as they are. The automatic on/off feature feels like magic. There's no need to hold down a button for several seconds; you simply put them down or pick them up, and they respond naturally. It takes some time to get used to the touch controls, but they are quite responsive, and you'll have a lot of fun learning them. Connectivity and sound quality: Like any other modern wireless headphones, these use Bluetooth 5.0+. You get good audio quality when used with a smartphone, and when paired with a computer, two devices are available: a standard stereo output and a hands-free device for both output and input. These headphones have the unique feature of being able to be charged and used at the same time when connected directly to a computer through the supplied USB-C cable. However, what I'm about to describe isn't mentioned elsewhere: When the headphones are connected via Bluetooth and only media is played, the audio quality will be at most: 2 Channel, 16 bit, 44100 Hz (CD Quality), which is okay. It provides an average experience—not bad, but not outstanding. If these are used for playback and recording simultaneously (in an online game with voice chat, for example), the headphones will switch to hands-free mode, and the quality will be at most: Playback and Recording: 1 Channel, 16 bit, 16000 Hz (Tape Recorder Quality). The person on the other end will have no trouble hearing your voice, as the microphone does a good job isolating environmental noise, but the playback quality will be horrible. So, if you were expecting to use the Momentum 4 wireless for streaming or similar purposes, look elsewhere. In other words, these headphones can't play back high-quality audio and record from the microphone at the same time (neither via Bluetooth nor USB-C). Finally, there's wired mode with USB-C, where you can truly experience the Momentum 4's sound quality at its best: 2 Channel, 16 bit, 48000 Hz (DVD Quality), and I have to say, the sound quality is noticeably better than my XM5's and QC-35's, without a doubt. I give these headphones 5 stars because of the sound quality in wired mode and the outstanding battery life.

Los he usado poco, aunque es muy práctico por el bluetooth, son algo estorbosos para mi que no estoy acostumbrada a usar audífonos de este estilo, el sonido es muy bueno, neutro. El panel táctil es muy sensible entonces hay que tener cuidado de no estar clickeandolo sin querer. Los recomiendo ampliamente.

Für mich als hochsensible Asperger mit Adhs die beste Investition seit Langem. Zuvor hatte ich mit In-Ears Musik gehört, die oft unpraktisch waren und mir nur Ohrprobleme verursacht haben. Ich höre für mein Leben gern Musik zum runterkommen. Daher war ich auch bereit, Etwas zu investieren. PRO's: Komfort: sitzt angenehm an der Ohrmuschel und auf dem Kopf. Auch nach Stunden Tragen immer noch bequem. Klang: unfassbar klarer Sound. Laut Musik hören macht richtig Spaß und fühlt sich angenehm an. Ob Rock, Metal oder Techno. Auch Musik in 8d gibt der Kopfhörer mega geil wieder! Noise cancelling: eine wunderbare neue Erfahrung. Für meine sensiblen Antennen ist es ein wahrer Segen, die Umwelt auszuschalten und voll in die Musik einzutauchen. Das klappt mit den Kopfhörern wunderbar. App: in der App lassen sich verschiedene Klang Modi und individuelle Bässe einstellen. Touchfeld an der Ohrmuschel: super praktisch mit dem Finger in verschiedene Richtungen wischen um zu pausieren, zum nächsten Titel oder zurück, oder einen Anruf entgegennehmen, klappt bestens! Zudem sind die sehr lange Akkukapazität und die Möglichkeiten Bluetooth oder Kabel, weitere Pluspunkte. Contra: einziger Minuspunkt ist wohl der hohe Preis. Wer aber oft und gerne Musik hört und in intensive Klänge abtauchen will, bekommt auch ordentlich was. Bin super happy mit den Kopfhörern und empfehle sie gerne weiter!
