Sennheiser MOMENTUM 4 Wireless Headphones, Bluetooth for Crystal-Clear Calls w/ Adaptive Noise Cancellation, 60h Battery Life, Customizable Sound & Lightweight Folding Design, Black

The best earphones I’ve ever owned
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.

Awesome headphones…. but…
I have owned the Momentum 2’s for many years and love them. But, after the battery started to fail and took over 8hrs to charge I decided to upgrade. Here are my thoughts:Sound – Really good, but different to the 2’s. Took some time to get used to but I really like the sound now.Battery – Amazing. 60 hours is huge and makes such a difference not having to charge so regularly.Comfort – The 2’s were great but these are on another level. Can wear for hours on end without getting hot or ever feeling uncomfortable.Look – The 2’s looked amazing with the ivory colour. These look ok, but do not stand out. Build quality is excellent. No creaking on mine.Controls – I hate the touch controls and miss having a button to adjust the volume. If adjusting, then it is easy to activate a control. Changing the volume is hit and miss. I have turned touch controls off as they are too unreliable. It would be good to switch just some of the controls off and just have volume, or have the ability to change via the app. Maybe having less controls would help it work better.Connectivity – multiple devices works fine. I’ve had no issues but it niggles me that when you connect, you get a lovely voice that tells you it has connected, but when you connect a Bluetooth device, a lady from Essex tells you it is connected. It is so wierd they use different voices for different announcements.All in all a great pair of headphones but I wish Sennheiser would address some minor niggles.

Very happy with these. I have always liked the sound quality and profile of Sennheiser headphones, but I did not like the Momentum 2 as I found them incredibly uncomfortable and did not have very well-implemented controls and software. The battery life is fantastic. I have only charged them once, and they are still at 60% months later despite using them every few days. These also feel more premium and comfortable than their previous generations. Noise-canceling seems better implemented; I always felt like I was wearing a diver’s helmet with the Momentum 2 ; these feel more natural sounding even with ANC turned on. I had no issues pairing them; the newer support app is much better designed. This is a worthwhile upgrade if you have an older Sennheiser Momentum generation.

(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.
