In short
Keep Sennheiser MOMENTUM 4 Wireless, or buy one used, if 60 hours with noise cancelling on matters more to you than aptX Lossless. Momentum 5 replaced it with aptX Lossless, eight noise-cancelling mics, Bluetooth 5.4 and a battery you can swap, but it's rated for 57 hours. Momentum 4 folds flat, weighs about 293 grams and handles aptX Adaptive and two connected devices; its 700 mAh cell is sealed.
Who it is for
- Owners whose pair still works. Momentum 5 doesn't last longer, so moving up only pays off if you want its codec, microphones or swappable battery.
- Travelers who'd rather charge less often. Sennheiser rates Momentum 4 for up to 60 hours with noise cancelling on, and it folds flat into a slim hard case.
- Used buyers whose phones top out at aptX Adaptive. Momentum 4 supports aptX Adaptive, aptX, AAC and SBC; aptX Lossless and Snapdragon Sound arrived with Momentum 5.
- Anyone splitting time between a phone and a laptop. Sennheiser's manual lists two active connections and up to six saved pairings.
Who should skip it
- Snapdragon Sound phone owners who want aptX Lossless. Momentum 4 stops at aptX Adaptive.
- Anyone buying new who wants Sennheiser's current model. That's MOMENTUM 5 Wireless.
- Anyone who works out in their headphones. Momentum 4 has no published water resistance.
What sets it apart
- Up to 60 hours of music with noise cancelling on, three more than Momentum 5's 57, both measured by Sennheiser on an iPhone at mid volume.
- Two Bluetooth connections at once, and up to six remembered devices.
- Folded flat, it measures 180 × 195 × 46.3 mm (7 × 7.67 × 1.82 in) and travels in a slim hard case.
- A 42 mm dynamic driver rated at 106 dB SPL, with a passive mode (60 ohms) for listening over the analog cable.
Caveats
- The 700 mAh battery is sealed, so a used pair comes with whatever battery health it has. Momentum 5's cell is the one you can swap.
- Box contents vary by pack: the analog cable and carry case are listed for the typical pack, so confirm a used pair still has them.

Keep it, buy it used, or move to Momentum 5
Momentum 4 came out in 2022, and Sennheiser has since replaced it with MOMENTUM 5 Wireless. The newer model doesn’t last longer on paper. It changes the codec, the microphones and the battery design.
| Spec | Momentum 4 | Momentum 5 |
|---|---|---|
| Battery, noise cancelling on | Up to 60 hours | Up to 57 hours |
| Codecs | SBC, AAC, aptX, aptX Adaptive | Adds aptX Lossless and Snapdragon Sound |
| Bluetooth | 5.2 | 5.4 |
| Microphones | 4, two per side | 8 digital, for noise cancelling |
| Battery cell | 700 mAh, built in | 700 mAh, swappable |
| Weight | About 293 g | About 290 g |
| App | Smart Control | Smart Control Plus |
Keep it if yours still works. It’s rated for more hours than its replacement, holds two connections at once and folds flat, so moving up buys features rather than stamina.
Buy one used if 60 hours and aptX Adaptive cover what you need, at a price that reflects a battery you can’t replace yourself.
Move to Momentum 5 for aptX Lossless and Snapdragon Sound, the extra noise-cancelling microphones, Bluetooth 5.4 and a cell you can unscrew and change.
Battery and charging
| Battery | Momentum 4 |
|---|---|
| Music over Bluetooth, noise cancelling on | Up to 60 hours (iPhone, mid volume) |
| Full charge (USB-C, 5 V, 800 mA max) | About 2 hours |
| 5-minute charge | Up to 4 hours |
| Cell | 700 mAh lithium-ion, built in |
Above 30°C, a full charge may take longer than the usual 2 hours.
Sound, noise cancelling and calls
Sennheiser rates the 42 mm dynamic transducer at 106 dB SPL and under 0.3% distortion, and it covers 6 Hz to 22 kHz. Impedance is 470 ohms active and 60 ohms passive. Over Bluetooth 5.2 (class 1) it supports SBC, AAC, aptX and aptX Adaptive, and aptX Adaptive only works with a source that has it.
Noise cancelling is Sennheiser’s hybrid adaptive ANC, with Transparency Mode for letting outside sound through. Calls go through two beamforming microphones per side. The Smart Control app on iOS and Android handles the EQ, sound modes and firmware updates.
In the box and colors
The typical pack holds the headphones, a carry case, a USB-C charging cable, an analog audio cable and documentation. Momentum 4 weighs about 293 g. It launched in Black and White (article numbers 509266 and 509267), and Sennheiser later added Graphite, Brown, Teal, Copper and Denim.
Price
Sennheiser announced Momentum 4 (model M4AEBT) on 9 August 2022 at $349.95, opened pre-orders the same day and started retail sales on 23 August 2022. Now that Momentum 5 has replaced it, you’ll mostly find it used. A fair price accounts for the sealed battery’s age, so compare a few listings before you buy. Momentum 4 vs Momentum 5 goes through the pair in more detail.

Frequently asked questions
Should I upgrade from Momentum 4 to Momentum 5?
Only if you'll use what's new: aptX Lossless and Snapdragon Sound, eight noise-cancelling mics, Bluetooth 5.4 or a battery you can swap. Momentum 5 is rated for 57 hours to Momentum 4's 60, so battery life isn't a reason to move.
Can I replace Momentum 4's battery?
No. The 700 mAh lithium-ion cell is built in. Momentum 5 uses a 700 mAh cell you can swap with a Phillips-head screwdriver.
How fast does Momentum 4 charge?
About 2 hours for a full charge over USB-C. For quick top-ups Sennheiser gives two figures that don't line up: 5 minutes for up to 4 hours in its specifications, and 10 minutes for about 6 hours in its marketing.
Can I listen to Momentum 4 with a cable?
Yes. The typical pack includes an analog audio cable, and Momentum 4 has a passive mode, rated at 60 ohms, for wired listening.
