Sennheiser Momentum 4 Wi-fi Headphones, Bluetooth for Crystal-Clear Calls w/Adaptive Noise Cancellation, 60h Battery Life, Customizable Sound & Light-weight Folding Design, Graphite

Ignore the complaints, these are the best.
Let me say upfront I am a long-time audiophile. I’ve been immersed in all things high-end audio for more than 40 years, and listened to a lot of stuff, including headphones. Until recently, I’ve avoided all BT/wireless headphones because they presented too much compromise for my tastes. Noise cancellation adversely effected audio quality and/or gave me a headache. Bluetooth simply didn’t cut it for prolonged enjoyment because of the lower, compressed resolution and frequency.But, that all changed in late 2022. On a whim, I tried the newish Sony WH-1000XM5 and was surprised at how good they sounded. The noise cancellation was excellent with little of the rushing elevator sound–and boy, the sound was terrific. For the first time I felt like using a wireless headphone wasn’t a big step-down from wired. The M5’s soundstage was truly impressive, rivaling my Focal Clear MG wired ‘phones. Plus, the M5s were much lighter, more portable, and a bit more fun. The new Sony’s were a magnitude better than the older Sonys, as well as anything wireless I’d heard before.That got me wondering: If the Sony’s are this good, maybe something by Bowers and Wilkins or Sennheiser would be even better. After all, Sony caters to the mass market, which is generally not that discerning when it comes to audio. Whereas, B&W and Sennheiser typically aim more for the smaller, high-end, audiophile market. So, I started comparing the MX5 to the new B&W Px7 S2 and new Sennheiser Momentum 4 Wireless.Here’s what I found:In the past, like the Sonys, the B&Ws and Sennheiser wireless ‘phones were disappointments, falling far short (for me) of their wired, non-NC counterparts. No longer, because the new models are dramatically better. Without going into lots of detail (something audiophiles love to do), both the Px7 S2 and the Momentum 4 are a leap forward in every way than their predecessors. Are they better than the MX5, yes, but not by much. As others have said, the MX5 has better software, better NC, is very portable, and pretty comfortable. For many, the slight compromise in audio quality may not be a big deal. I could easily live with the MX5. However, my priority is sound quality since I seldom use NC, and, even if the software of the B&Ws and Sennheisers is only acceptable.Therefore, it came down to the Px7 S2 vs. Momentum 4 for me. The Px7 S2 is much nicer to look at, exuding high quality. The Momentum 4, not so much. In fact, they look like an MX5 knock-off with a few upscale touches. The software of both the Px7 S2 and Momentum 4 is mediocre at best, albeit functional.Now about the sound. The Px7 S2 sound really, really good. Bass, Midrange, Treble are all top notch, if not perfect. They’re fun to listen to, with a wide soundstage and energetic dynamics. That said, they’re tuned to emphasize the lower frequencies a bit too much for my tastes. At first, this makes music and voices more vibrant and robust, but, over time, it gets tiring, and you’re realize what you’re hearing isn’t all that accurate. If I hadn’t listened to the Momentum 4s, I probably would have been quite happy with the Px7 S2.But, I did listen to the Momentum 4. It edges out thePx7 S2 and MX5 with its overall excellent balance and accuracy. Nothing is exaggerated: voices, instruments, timbre, tone are all just right to my ears. Maybe not as exciting as the Px7 S2 upon first listen, but the Momentum 4s seduce you the more you use them. There’s no need for lots of equalization, or fiddling to get the sound right; its all been done at the factory. Besides the accurate representation of voices and instruments, the Momentum 4s are monsters when it comes to soundstage. The placement of everything is wide, yet accurate. You can feel the space and air between different instruments, and where the singer is in the studio or stage. Layering and detail are pretty amazing considering these are bluetooth, closed-back ‘phones. Sennheiser (Actually: Sonova, because Sennheiser sold their headphone division to this maker of hearing aids in 2021.) did their homework when it came to the Momentum 4. Plus, that 60 hours of battery life is icing on the cake.Let me say this in conclusion. You won’t go wrong with any of these three headphones. They’re all great. I preferred the Momentum 4 because it represents the overall most satisfying package for the money, but you might prefer the Px7 S2, or the MX5, more. One last word, regarding the buggy software of the Momentum 4: I found none. With the latest updates, Sennheiser/Sonova seems have fixed the issues of poor connectivity and consistency. All system functions worked perfectly the entire time I’ve been using the Momentum 4s. Enjoy!

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)EspañolCalidad 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.

I recently picked up the Sennheiser Momentum 4 headphones, seeking a balance between professional-grade audio and personal versatility. After using them extensively for work, podcasts, gym sessions, and entertainment, I can confidently say these headphones meet (and exceed) expectations in many ways. Here’s my take:Sound QualityThe Momentum 4 shines across the board:Highs:Crisp and balanced, these headphones effortlessly handle atmospheric tracks while maintaining richness and neutrality on more energetic tunes. The highs are detailed without being harsh.Mids:Vocals are consistently clear and focused, no matter the genre. While there’s a slight recession in the lower mids and a delicate touch in tonal shifts, this neutrality ensures vocals and instruments never feel overshadowed. It’s an ideal choice for those who appreciate a clinical and polished sound signature.Bass: If you love bass, the Momentum 4 will impress. The sub-bass packs a punch, delivering a visceral experience. Despite its depth, the bass remains textured and never overwhelms the mids or highs, making it both exciting and refined.Imaging: While instrument separation is excellent, directional clarity could be sharper. Vocals are precise, but subtle shifts in instrument staging can feel less noticeable in complex tracks.Active Noise Cancellation (ANC)In a noisy office, the Momentum 4 is a lifesaver. Constant background rumbles are effectively eliminated, but sharp, sudden noises occasionally break through. Interestingly, the ANC’s effectiveness improves slightly when facing the noise source—an odd but minor quirk.Comfort and FitComfort is subjective, but the Momentum 4 does a solid job: The plush padding makes them comfortable for long listening sessions, though the fit is a bit tight around the neck when not in use.The earcups rotate well, providing a secure and adjustable fit that works for extended wear.Battery Life and FeaturesBattery life is a standout feature, far outlasting competitors with an incredible lifespan. The quick-charging USB-C functionality is a lifesaver for busy schedules, and the ability to power them off manually is a thoughtful touch.Feature-wise, they strike a balance between simplicity and functionality:The basic EQ and ANC controls are effective and intuitive. The sidetone feature is a small but appreciated addition for calls, and the auto-pause functionality works seamlessly. While not overloaded with extras like spatial audio or deep app integration, the essential features are well-executed, and the app—while sometimes buggy—is user-friendly enough.DesignIs understated and utilitarian. While they won’t turn heads, their discreet design makes them perfect for both professional environments and casual outings. Personally, I appreciate this “keep-it-simple” approach, even if it lacks a premium feel.ConclusionMomentum 4 delivers exceptional audio quality, impressive battery life, and practical features, making them a great choice for both work and leisure. While they aren’t packed with flashy extras, their focus on performance and reliability makes them a standout option. Whether you’re drowning out office chatter, enjoying a podcast, or diving into a bass-heavy workout playlist, the Momentum 4 adapts seamlessly.The ability to switch seamlessly between two devices is amazing to me. I need not have to mess about with the settings on my laptop or phone for them to automatically connect.For anyone seeking headphones that balance professional needs with personal versatility, these are hard to beat.
