SennheiserMOMENTUM 4 Wireless Special Edition Headphones, Bluetooth for Crystal-Clear Calls w/Adaptive Noise Cancellation, 60h Battery Life, Customizable Sound, Black/Copper

TL:DR While they may have some idiosyncracies, they are totally worth learning to manage as the sound, battery, and general functionality is excellentI've been using these for the past 5 months and can honestly say they are one of the best pairs of headphones I've used in a VERY long time. While they might not be "perfect" in all areas, they are excellent in enough to assuage the issues.The sound quality via bluetooth is absolutely EXCELLENT, they have a -very- wide soundstage compared to a fair number of bluetooth headphones I have tried, and also have a very clean, separated sound, all the elements are clear and distinct to the point I've heard things in songs and videos that I had not before even listening through my monitor set up. I've not tried them wired, where they could be even better because the BT is so good (YMMV I spend time shaping the EQ in the app which is well worth the time)Battery life is top tier, I wear them while commuting and on breaks, and often wear them of an evening connected to my PC and seem to only have to charge them every few weeks. They also have a neat function were they pause the music when you take them off and seem to go into sleep mode until you put them back onThey can be connected to multiple devices, although this is where some minor issues start to appear. I have mine connected to my phone and my pc via a bluetooth dongle - unless you don't manually put the headphones to sleep using the power button, you can sometimes have devices register a connection to the headphones, which can pause things you're listening to through speakers.They come with a sturdy headphone case that has spaces for, and includes, relevant cables e.g. USB and headphone, and the headphones fit very nicely in to it, which is useful as they do not fold in any way. They are portable with some planning.. or a thin neck I guess!The touch controls are a great idea and work really well in principle... but as alluded to I have a thick neck, and it is tremendously easy to "press play" on the earcap with my chin 😅Also the double tap for ANC doesn't register as well as it should, but the increasing/decreasing ANC motion does.There is an app that seems expected to get, but is also totally worth the download. Has its own equaliser to be configured, as well as other ANC controls, being able to configure sound zones using the ANC microphones and others beside.I got them with a fairly good discount in a sale, but would not have been disappointed if I had paid full price

The Sennheiser MOMENTUM 4 Wireless headphones bring significant upgrades to Sennheiser's premium line, competing directly with top-tier noise-canceling headphones from brands like Sony and Bose.Controls:The MOMENTUM 4 employs intuitive touch controls on the ear cups for play/pause, volume adjustments, and track navigation. Sennheiser has also included wear-detection sensors, pausing playback when you remove the headphones and resuming when you put them back on.Connectivity and App Integration:Equipped with Bluetooth 5.2, the MOMENTUM 4 offers a reliable, high-quality connection. The Sennheiser Smart Control app provides customization options, including EQ settings and a sound personalization feature that adjusts based on your listening preferences.Battery Life:With a remarkable 60-hour battery life (at moderate volume with ANC on), these headphones outlast most competitors in the category. Quick-charging provides about six hours of playback with just a 10-minute charge.Noise Cancellation (ANC) and Transparency Mode:The Adaptive Noise Cancellation is quite effective, especially in noisy environments like planes or public transport. Transparency Mode allows external sounds in, which is useful for conversations without removing the headphones.Sound Quality:Sennheiser is known for its audio fidelity, and the MOMENTUM 4 stays true to this legacy. It delivers a clear, balanced, and rich sound profile, which can also be customized in the app. Here’s a breakdown of its performance across sound characteristics:Bass: Deep, punchy bass without being overbearing, making it suitable for genres like hip-hop, electronic, and pop.Mids and Highs: Vocals and instruments are detailed, and highs are crisp without becoming harsh. This makes it ideal for everything from classical and jazz to rock.Soundstage: The MOMENTUM 4 has an impressively wide soundstage for closed-back headphones, allowing for excellent separation and positioning of sounds.The headphones also support high-quality codecs, including aptX Adaptive and AAC, which enhance sound quality over Bluetooth.Pros:Outstanding battery life (up to 60 hours) with fast-charging capabilities.Exceptional sound quality that’s clear, detailed, and customizable.Effective Adaptive Noise Cancellation that competes well with top ANC models.Comfortable and lightweight design, suitable for extended use.Stable Bluetooth 5.2 connectivity with support for high-quality codecs.Cons:Less distinctive design compared to previous MOMENTUM models, which may disappoint fans of the original look.Touch controls can be somewhat sensitive, occasionally leading to accidental triggers.ANC isn’t industry-leading; while it’s very good, it’s slightly less effective than Sony’s and Bose’s top models in extremely noisy environments.Final Verdict:The Sennheiser MOMENTUM 4 Wireless headphones are an excellent choice for listeners who prioritize sound quality, comfort, and long battery life. They strike a great balance between premium audio performance and advanced features like ANC and transparency mode, making them versatile for daily use, travel, and dedicated listening sessions.

I've been a fan of Sennheiser for many years. Their sound usually 'works' for me. That said, while these headphones sound good enough, they don't really blow me away, no matter how much I tweak their EQ etc. The sound is fine, but it doesn't really 'breathe'.Still, they sound good enough, and their battery life is stellar. The case is good, if a bit bulky, and they are quite comfortable for me. The bluetooth connection seems stable.The software as rather flaky though. On many occasions, the touch controls just stop working, until I power on and off again. Routinely, I get an audio cue to indicate that something has happened, even though I was not using any controls, and it's not clear what it signifies. And from time to time, the ANC randomly switches into and out of transparency mode, without me asking it to. The headphones regularly instruct my phone to start playing music, again without me asking them to.The ANC itself is OK. I don't have much to compare it to, but it works well with constant noise (think train or bus engines). It's less impressive with irregular noise caused by voices etc, but I guess that's to be expected.Honestly, while these are fine, if I'm ever in the market to replace them, I doubt I will consider Sennheiser again. I just get the impression that some other brands will perform better.
