Hi Rockboatground, Thank you so much for your positive feedback in our newest Industry Leading Noise Canceling Overhead Headphones WH1000XM4! The WH1000XM4 utilizes DSEE Extreme (Digital Sound Enhancement Engine) which upscales compressed digital music files in real-time. Dynamically recognizing the instrumentation, musical genres, and individual elements of each song, such as vocals or interludes, it restores the high-range sound lost in compression for a richer, more complete listening experience. Thank you for choosing Sony! David

Hi Celestino Macedo, We regret to hear that the headphones are not performing to your standards. Make sure to install the latest software version of the headphones (via the Sony Headphones Connect app) for optimum performance. These steps may help improve your experience with the sound quality: -Keep the headset away from a microwave oven, wireless LAN device, etc. -Bring the headset closer to the Bluetooth device. Remove any obstacles between the headset and the Bluetooth device. -Keep the headset away from a TV. -When playing music, if the headset and the transmitting Bluetooth device are connected via an HFP or HSP Bluetooth connection, switch the Bluetooth connection to A2DP with the connected device. -When using a video calling application on a computer, switch the Bluetooth connection to HFP or HSP with the computer. During a video call, sound quality may become low due to the conditions of the communication line. -When listening to music from a computer on the headset, the sound quality may be poor (e.g., difficult to hear the singer’s voice, etc.) for the first few seconds after a connection is established. This is due to the computer specifications (priority on stable connection at the start of transmission and then switches to priority on sound quality several seconds later) and is not a headset malfunction. If the sound quality does not improve after a few seconds, use the computer to establish an A2DP connection. As for the operations on your computer, refer to the operating instructions supplied with the computer. -When [Connect to 2 devices simultaneously] is turned on with the “Sony | Headphones Connect” app, LDAC cannot be used. If you want to use LDAC for music playback, turn [Connect to 2 devices simultaneously] off. Sony takes all feedback seriously. Rest assured that this will help us improve our products. For further assistance regarding your product, we highly recommend visiting our Sony Global Web site for information on contacting the Sony Support Center in your region at http://www.sony.net/SonyInfo/Support/.
