Hi Skwork, While we are glad to hear that you are happy with the noise-cancelling feature and comfort of the WH-1000XM4 Headphones, we are sorry to hear that you are experiencing audio stutter on the headphones and you are having trouble with the multipoint connection. We'd love to troubleshoot the issues that you are having and make this a better experience for you. In the meantime, please follow these steps to troubleshoot the issues. First, please make sure that the headphones are up to date as this will improve the overall performance of the headphones. You may use the Headphones Connect app to update the WH-1000XM4 Headphones. For the audio, please make sure that the sound quality mode is set to “Priority on stable connection” mode. Bluetooth communications may be disabled, or noise or audio dropout may occur under the following conditions. -When there is a human body between the headset and the Bluetooth device In this case, put the Bluetooth device in the same direction as the antenna of the headset to improve the Bluetooth communications. -There is an obstacle, such as metal or a wall, between the headset and the Bluetooth device. In places with wireless LAN, where a microwave oven is used, electromagnetic waves are generated, etc. -The situation may be improved by changing the wireless playback quality settings or fixing the wireless playback mode to SBC on the transmitting device. For details, refer to the operating instructions supplied with the transmitting device. -Because Bluetooth devices and wireless LAN (IEEE802.11b/g/n) use the same frequency band (2.4 GHz), microwave interference may occur and result in noise, audio dropouts, or communications being disabled if this headset is used near a wireless LAN device. In such a case, perform the following steps. -If this headset is used within 10 m (30 feet) of a wireless LAN device, turn off the wireless LAN device. -Use this headset and the Bluetooth device as near to each other as possible. -If you are enjoying music with your smartphone, the situation may be improved by shutting down unnecessary apps or restarting your smartphone. For the multipoint connection, please make sure to download the Sony | Headphones Connect app on one of the devices and make sure it has the latest update. Both source devices must support Bluetooth capability. When pairing the headphones with any device, make sure to select WH-1000XM4, rather than LE_WH-1000XM4 on the source device. It may take up to one minute before WH-1000XM4 appears on the screen.

Hi Felix, Thank you for your comprehensive review of the Sony WH-1000XM4 headphones. It's fantastic to hear your positive feedback on the noise cancellation, audio quality, build, and comfort. Your observation about the battery life and the headphones' compatibility across different phone platforms is insightful. Sony headphones perform well with both iPhones and Android devices. You may notice better sound quality on Android due to the LDAC codec, which iOS does not support as easily, enabling higher quality audio transmission. The clamping force you've noted is indeed a design choice that aids in better noise isolation, contributing to the overall noise-cancelling performance. This model remains a top pick for those seeking premium noise canceling headphones. Thank you for choosing Sony! -Jess
