What’s it like to use the Sennheiser MOMENTUM True Wireless 4 compared to the Bose QuietComfort Ultra Earbuds?

Bose QC Ultra vs Sennheiser Momentum 4

The Sennheiser MOMENTUM True Wireless 4 have a fashionable, jewelry-like design with metallic accents. Though on the larger side, Sennheiser includes three sizes of concha fins to help get a secure and comfortable fit. The ovoid nozzles don’t need to be jammed deep into your ear canals.

The Bose QuietComfort Ultra Earbuds also use an ovoid nozzle shape that sits nicely in the ear without pressure on the ear canal. For some people, this shape fits ears better than cylindrical nozzles. The earbuds themselves have a chunky, futuristic design reminiscent of Star Trek props.

How do you control the Sennheiser MOMENTUM True Wireless 4 and Bose QuietComfort Ultra Earbuds?

Both earbuds use touch capacitive touch panels for controls to avoid breaking the ear tip seal when inputting commands.

Should you use the apps of either Sennheiser MOMENTUM True Wireless 4 or Bose QuietComfort Ultra Earbuds?

For the Sennheiser MOMENTUM True Wireless 4, you’ll want to use the excellent Sennheiser Smart Control app. It offers an equalizer, sound personalization, firmware updates, and the ability to program the earbuds for different scenarios based on location.

The Bose Music app is essential for enjoying features like the immersive audio mode, customizing control gestures, and firmware updates. Still, the in-app EQ isn’t all that useful for tuning the Bose QuietComfort Ultra Earbuds.

How do the Sennheiser MOMENTUM True Wireless 4 and Bose QuietComfort Ultra Earbuds connect?

The Sennheiser MOMENTUM True Wireless 4 uses Bluetooth 5.4 and supports SBC, AAC, aptX Adaptive, aptX Lossless, and, after a firmware update, LE Audio with the LC3 codec. They can also connect to Auracast broadcast audio if available.

The Bose QuietComfort Ultra Earbuds use Bluetooth 5.3 with SBC, AAC, and aptX Adaptive codec support. They also offer Snapdragon Sound with aptX Lossless for high-res, low-latency audio on compatible devices.

The Sennheiser MOMENTUM True Wireless 4 does well against its competitors in terms of battery life.

In standardized testing, the Sennheiser MOMENTUM True Wireless 4 provided 7 hours and 45 minutes of battery life on a single charge, outperforming the Bose QuietComfort Ultra Earbuds, which lasted 6 hours and 11 minutes.

However, both have additional charges provided by their respective cases and support fast charging to extend battery life throughout the day.

Both earbuds offer excellent active noise cancelation performance. In testing, the Bose QuietComfort Ultra Earbuds provided slightly better overall noise canceling, reducing perceived loudness by up to 90% in some ranges. They can silence noise above 1kHz by up to 39dB, which is outstanding.

The Sennheiser MOMENTUM True Wireless 4 were still highly impressive though, with 83% average noise attenuation and even physically blocking almost 50dB in the higher ranges. Like all earbuds, they require a good ear tip seal to realize their full noise canceling potential.

Do the Sennheiser MOMENTUM True Wireless 4 sound better than the Bose QuietComfort Ultra Earbuds?

Multi-Dimensional Audio Quality Scores (MDAQS)

Based on their objective scoring from the MDAQS algorithm, the Sennheiser MOMENTUM True Wireless 4 provides better overall sound quality out of the box compared to the Bose QuietComfort Ultra Earbuds.

The MOMENTUM True Wireless 4 earned an overall MDAQS score of 4.8 out of 5, with excellent marks for Timbre Reproduction (4.9) and Immersiveness (4.4). In comparison, the QuietComfort Ultra Earbuds scored 4.4 overall, with lower Distortion (2.2) and Immersiveness (3.9) scores.

  • Timbre (MOS-T) represents how faithfully the earbuds reproduce the frequency spectrum and temporal resolution (timing information).
  • Distortion (MOS-D) represents non-linearities and added noise: higher scores mean cleaner reproduction.
  • Immersiveness (MOS-I) represents perceived source width and positioning: how well virtual sound sources are defined in three-dimensional space.

Objective Measurements

Loading chart ...

Compared to our headphone preference curve, the Bose QuietComfort Ultra Earbuds show a strong over-emphasis in bass and treble, potentially leading to sounds that can feel overwhelming and less natural. The Sennheiser MOMENTUM True Wireless 4 features a slight low-end boost and a manageable high-end underemphasis, making them more versatile and suitable for a wider range of music. Both can be tweaked with EQ settings.

One advantage of the Bose QuietComfort Ultra is support for Snapdragon Sound. While it might sound trite, having this compatibility opens the door to a much better Bluetooth codec than previously available aptX Lossless. This codec has some serious bragging rights in its latency and data transfer rate (even though some compression is necessary).

Do the Sennheiser MOMENTUM True Wireless 4 or Bose QuietComfort Ultra Earbuds have a better microphone?

Bose QC Ultra vs Sennheiser Momentum 4 earbuds

Neither earbud delivers exceptional microphone performance. The Sennheiser MOMENTUM True Wireless 4 mic quality is highly variable, with poor wind noise rejection.

The Bose QuietComfort Ultra Earbuds mics performed slightly better for calls, though the small size limits fidelity compared to dedicated mics.
