What You'll Learn
The QC35 II leak sound at moderate volumes
The QC35 II leaks sound at moderate volumes. While the headphones are comfortable, have a well-balanced sound profile, and are good at noise isolation, they do have some sound leakage issues.
One user reported that they can use them in a silent room with a person next to them who cannot hear their music, even when the volume is enjoyable for them. However, they also reported that the headphones bleed sound beyond 30% volume, which is not ideal if you listen to music at a loud volume. Another user claimed that the sound leakage is very bad and that they stopped wearing the headphones because they felt like people could hear their music.
Other users have also reported that the sound leakage is noticeable, and that people around them can definitely hear their music at moderate volumes. The ear pads are comfortable but don't seal well, which contributes to the sound leakage issue.
When compared to other headphones, the QC35 II has been found to leak more sound than the Beats Studio3 Wireless, the Sony WH-1000XM4 Wireless, and the Sennheiser Momentum 2.0 Wireless. The sound leakage is a common issue that has been reported by many users, and it is something to consider if you are planning to use these headphones in quiet places or where you need to be considerate of others.

Bose QC35 II noise cancellation is inferior to Sony's WH-1000XM4
The Bose QC35 II and Sony WH-1000XM4 are two of the biggest names in audio technology. While both offer excellent noise-cancelling capabilities, the Sony WH-1000XM4 has several features that make it a superior product.
Firstly, the Sony WH-1000XM4 has thicker ear pads, creating a better seal around your ears and reducing sound leakage. This is a notable issue with the Bose QC35 II, as many users have reported that the headphones leak sound, even at moderate volumes. This can be disruptive in quiet environments and may disturb others nearby.
Secondly, the Sony WH-1000XM4 offers a more modern and convenient USB-C connection, while the Bose QC35 II uses an outdated microUSB charging port. The Sony headphones also feature auto-pause/resume functionality, which is lacking in the Bose model.
Additionally, the Sony WH-1000XM4 provides a more advanced level of customisation and control. Through the Sony Headphones Connect app, users can program the Custom button to access the integrated voice assistant or toggle noise cancellation. The app also offers additional functions like noise-cancelling optimisation, ambient noise control, and equalizer customisation. In comparison, the Bose QC35 II has physical buttons and a multifunction button to access its smart assistant and toggle noise cancellation settings, which may not offer the same level of flexibility and convenience.
While the Bose QC35 II has its strengths, such as its comfort and ease of use, the Sony WH-1000XM4 surpasses it in terms of noise cancellation, sound leakage prevention, connectivity, and software features. For consumers seeking the latest technology and a more comprehensive noise-cancelling experience, the Sony WH-1000XM4 is the superior choice.

The QC35 II's closed-back design and ANC feature improve noise isolation
The Bose QuietComfort 35 II/QC35 II Wireless 2018 headphones are designed with a closed-back feature and an Active Noise Cancellation (ANC) feature. These features improve noise isolation and reduce sound leakage. The closed-back design of the headphones means that the outer side of the ear cups is sealed shut, preventing sound from escaping and improving noise isolation. This design is often chosen for noise-cancelling headphones as it helps to block out external noise and prevent sound leakage.
The ANC feature on the QC35 II headphones also contributes to their superior noise isolation capabilities. This technology uses microphones to monitor and counter ambient noise, creating a quieter environment for the listener. By actively cancelling out background noise, the ANC feature further reduces sound leakage from the headphones.
While the closed-back design and ANC feature of the QC35 II headphones improve noise isolation, it is important to note that they do not completely eliminate sound leakage. Some users have reported that the headphones leak sound, particularly at moderate to high volumes. At lower volumes, the sound leakage is less noticeable, and individuals in close proximity may not be able to hear the music.
The QC35 II headphones are also designed with comfort in mind, making them suitable for long listening sessions. They have a well-balanced sound profile and a lightweight, stable fit. The wireless design gives users more freedom, and the outstanding ANC feature provides peace and quiet during commutes or long travel days.
Overall, the combination of the closed-back design and ANC feature in the QC35 II headphones significantly improves noise isolation and reduces sound leakage. While some sound leakage may still occur at higher volumes, the headphones offer a superior listening experience with excellent noise cancellation and comfort.

The QC35 II leak sound at high volumes
The QC35 II leaks sound at high volumes. While the headphones are praised for their comfort and noise cancellation, several users have reported that the QC35 II leaks sound, particularly at high volumes.
One user noted that the sound leakage was so significant that they could hear the music playing from a distance. Another user shared a similar experience, stating that even at moderate volumes, people could hear their music. This is a concern for those who plan to use the headphones in quiet spaces or during commutes, as they may disturb others.
The sound leakage may be due to the design of the ear pads, which, while comfortable, may not seal well around the ears. This allows sound to escape, especially at higher volumes.
It is important to note that while some users have reported significant sound leakage, others have found that the sound leakage is not as severe. Some users have reported that even at moderate or low volumes, people nearby could not hear their music.
Compared to other headphones on the market, the QC35 II may leak more sound. For example, the Sony WH-1000XM4 Wireless headphones are reported to have better noise isolation and leak less noise. Similarly, the Sennheiser Momentum 2.0 Wireless/HD1 Wireless headphones are said to leak a lot less sound, making them a better option for noise-sensitive environments.
