The Sennheiser Momentum 5 headphones come in a surprisingly thin carry case, not just because the cans fold flat but also because they\u2019re a bit thinner than what you might expect from high-quality over-ear headphones.\u00a0<\/p>\n

The headphone\u2019s slender design helps keep the weight down to 290 g, which admittedly is still a little heavy compared to its competitors. Even so, a slightly off-centre padded headband and a clamping force that isn\u2019t too oppressive ensure that the Momentum 5 headphones are comfortable to wear for extended periods, even when wearing glasses. They get a little warm on the ears after a while, but certainly not as bad as some over-ear headphones.<\/p>\n
The slender design is impressive considering that Sennheiser has doubled the number of microphones to four per can. It\u2019s an even more impressive feat considering there is now a user-replaceable 700 mAh battery to help extend their lifespan. User-replaceable batteries have become rare in the push to make thinner gadgets, because the trade-off is usually a thicker device.<\/p>\n
On the outside, the Momentum 5 sticks with Sennheiser\u2019s typically understated aesthetics, with a matte plastic on the back of the cans and braided cloth on the exterior of the headband.<\/p>\n

There\u2019s a subtle power button on the bottom of the right can, alongside the USB-C and 2.5 mm audio ports. You miss out on a dedicated button for summoning your phone\u2019s smart assistant.<\/p>\n
You\u2019ll also find touch controls on the back of the right can, including a handy double-tap passthrough that disables noise-cancelling and lets in the outside world when you need to talk to someone. There\u2019s no conversation mode to automatically engage transparency mode when talking, but they do automatically pause your audio when you take them off.<\/p>\n
Inside the carry case, you\u2019ll find much-appreciated straps to hold the supplied USB-C and 2.5-to-3.5 mm audio cables, plus a pouch for extra accessories you might invest in. Unfortunately, Sennheiser doesn\u2019t include a dual-pronged airline adaptor for jetsetters.<\/p>\n
Sennheiser Momentum 5 specifications and priceDrivers42 mmResponse frequencyUSB & Bluetooth: 6 Hz to 40 kHz The Sennheiser Momentum 5 headphones are designed for hi-res lossless wireless listening, breaking new ground even compared to Sennheiser\u2019s top-shelf HDB 630.<\/p>\n For starters, the Momentum 5 are Bluetooth 5.4 wireless headphones with multi-point support for fast switching between two devices. It\u2019s a step up from Bluetooth 5.2 on the Momentum 4 and HDB 630. Sennheiser says the Momentum 5 will be upgraded to Bluetooth 6.0 in a future firmware update.<\/p>\n The Momentum 5 (and 4) is also compatible with Sennheiser\u2019s $80 BTD 700 Bluetooth USB dongle, which is thrown in for free with the HDB 630.<\/p>\n When it comes to sound quality, the Momentum 5 naturally supports the SBC and Apple-friendly AAC codecs, plus Qualcomm\u2019s aptX, aptX HD, aptX Adaptive and aptX Lossless. The standout is aptX Lossless (CD quality 16-bit, 44.1kHz), which is still only supported by a handful of Android handsets. All of this gives the headphones Qualcomm\u2019s \u201cSnapdragon Sound\u201d seal of approval, but in return, you miss out on Sony\u2019s rival LDAC hi-res codec.<\/p>\n Again, aptX Lossless puts the Momentum 5 at the front of the pack. It\u2019s missing on the HDB 630, while the old Momentum 4 lacks both aptX Lossless and aptX HD.<\/p>\n Of course, you also need devices and content that can make the most of aptX Lossless. These days, most streaming music services offer lossless audio, at least on their premium plans, but you might need to dip into the advanced settings to enable it.<\/p>\n The Momentum 5 also lets you make a wired USB connection to desktop and mobile devices using the supplied USB-C cable. This wired connection handles 24-bit\/96kHz audio for those who appreciate the finer things, but won\u2019t stretch to 192kHz.<\/p>\n Finally, you\u2019ve got that old-school 2.5 mm audio port, with a supplied 2.5mm-to-3.5mm cable so you can plug into devices with a headphone jack. Similar to most wireless headphones these days, they need to be powered up even when listening via the audio jack, so you can\u2019t fall back on the cable when you run out of juice.<\/p>\n When it comes to immersive audio, the Momentum 5 are Sennheiser\u2019s first to support Dolby Atmos and Spatial Audio with headtracking. Plus, they add a low lag mode for gaming.<\/p>\n To help block outside distractions, you\u2019ve got hybrid active noise cancellation with easy access to transparency mode when you need to hear the outside world.\u00a0<\/p>\n To tailor the sound, you can download the Sennheiser Smart Control Plus App, which makes it easy to customise things using the eight-band equaliser with preset sound modes. It\u2019s set to neutral with bass boost disabled by default.<\/p>\n There\u2019s also a new Sound Personalisation feature, plus you can adjust the noise cancelling or select adaptive. The app also lets you automatically switch presets depending on your location, which is handy when moving from the office to the gym.<\/p>\n The icing on the cake is the impressive 57 hours of playback, even with ANC enabled. If you don\u2019t need that much juice at your disposal, you can limit recharges to 80 per cent to help extend the life of the battery.<\/p>\n Quality<\/p>\n To give the Sennheiser Momentum 5 a chance to shine, I tested them with\u00a0the Motorola Edge 50<\/a>, which supports aptX Lossless \u2013 taking advantage of hi-res audio on Tidal and disabling normalise volume in order to squeeze out the best sound quality.<\/p>\n If your handset doesn\u2019t support aptX Lossless, it will fall back on the best version of aptX available, such as aptX Adaptive, otherwise it will opt for AAC. Even on a supported device like the Edge 50, getting aptX Lossless to work isn\u2019t easy.<\/p>\n I tried installing all the latest updates, disabling Dolby Atmos in Tidal and messing around with the handset\u2019s Bluetooth developer settings. In the end, I needed to downgrade Tidal\u2019s Wi-Fi streaming quality from Max (24-bit\/192 kHz) to High (16-bit, 44.1 kHz) before it would switch from aptX Adaptive to aptX Lossless.<\/p>\n Either way, the connection was understandably scaling down 24-bit audio to run over Bluetooth. The problem was that it seems to favour aptX Adaptive 48 kHz for music sources higher than 44.1 kHz. Dropping the quality to 16-bit, 44.1 kHz saw aptX Lossless kick in, which should be an improvement considering aptX Adaptive is still lossy.<\/p>\n Even then, things were temperamental, but I\u2019ll admit that I struggled to hear the difference. The step up from AAC is clear but, when taking high-quality audio from Tidal, both aptX Adaptive and aptX Lossless add subtle depth and emotion to a wide soundstage \u2013 making its presence felt on tracks like David Bowie\u2019s Space Oddity.\u00a0<\/p>\n With a warm but balanced sound, the Sennheiser Momentum 5 headphones bring to life audiophile favourites like Miles Davis\u2019 Kind of Blue and Norah Jones\u2019 Come Away With Me. The default preset isn\u2019t as bass-heavy as some headphones, but juicy bass lines still sound sweet in tracks like Macy Gray\u2019s Why Didn\u2019t You Call Me.<\/p>\n When it comes to active noise cancellation, the results are acceptable but far from best in class. Whether dealing with droning sounds and background chatter, they\u2019re outgunned by my trusty 10-year-old Sony MDR-1000X<\/a> over-ear headphones, which have served me well on countless international flights, as well as my AirPods Pro 2<\/a> earbuds.<\/p>\n However, the Momentum 5\u2019s transparency mode is impressive, offering natural sound that doesn\u2019t sound amplified or distorted.<\/p>\n Who are the Sennheiser Momentum 5 headphones for?<\/p>\n The $749 Sennheiser Momentum 5 may not be Sennheiser\u2019s flagship over-ear headphones, but they can hold their head high even alongside the $999 Sennheiser HDB 630.<\/p>\n If you\u2019d make the most of aptX Lossless and appreciate the option to replace the battery down the track, the Momentum 5 is certainly an attractive alternative. The sound quality is very impressive, although the active noise cancellation is a bit underwhelming \u2013 if that\u2019s your highest priority, then make sure you weigh up the alternatives.<\/p>\n
