Geekria Shield Headphone Case Compatible with Sony WH-1000XM4, WH-1000XM3, WH-XB910N Headphones, Replacement Protective Hard Shell Travel Carrying Bag with Cable Storage (Black)

Product Information

If the headset detects a problem while charging due to the following causes, the charging indicator (red) flashes. In this case, charge once again within the charging temperature range. If the problem persists, consult your nearest Sony dealer. The XM4's Adaptive Sound Control also makes a welcome return, with upgrades in tow. Adaptive Sound Control automatically adjusts the sound output depending on your situation – so it will detect if you are in a quiet meadow or a busy city street, for example, and tweak the audio accordingly. This is more advanced than the version found on the XM4, which relies on you running Sony’s NC Optimiser after you have changed surroundings to make sure you are getting the best noise-cancelling possible.

There are four ways to pair the headphones – Google’s Fast Pair or via a single tap with an NFC tag for instant pairing with an Android phone, using the Sony Headphones Connect app for Android or the iPhone and iPad, and manual pairing the old-fashioned way by holding down a button. If you've lost the charging case or one earbud, please send the remaining items to one of Sony's Authorised Services Centers, so that a replacement for the missing part can be acquired and reset with the remaining components. Find an Authorised Service Center. The earbuds and the charging case all have pre-set information that allows them to communicate with each other. Only an Authorised Service Center can configure your earbuds' settings to align their firmware versions. All three components (left earbud, right earbud, charging case) must be present during the configuration. The headphones are generally repairable ( iFixit teardown), and replacement parts, including the earpads, headband and mainboard are available. Sony did not comment on the use of recycled materials and does not publish environmental impact reports for headphones. It publishes annual sustainability reports and its roadmap to have zero environmental impact by 2050. Observations It felt as though Britney Spears was in the room with me as she worked through the provocative “Toxic”, while the intro to “Sexual Healing” had me looking over my shoulder as Marvin Gaye’s whispers for me to “get up, get up, get up, get up” and “wake up, wake up, wake up, wake up” darted between my left and right ears. *NSYNC’s “It’s Gonna Be Me” was less impactful, however, and my listening experience wasn’t all that different from when I listened to the regular version. They don’t look and feel quite as solid or premium as some competitors but they fold up for travel and appear durable in lightweight plastic. The are also fairly easy to repair and the battery is replaceable for a reasonable sum.

Just like the XM4, it supports Sony's hi-res LDAC music codec (but not aptX or aptX HD), DSEE Extreme (which upscales music files in real time), and Sony's 360 Reality Audio tech, giving you virtual surround sound. The Headphones Connect app has a full equaliser and options for customising noise-cancelling, controls and activating the DSEE Extreme sound enhancer.

The headphones come with a standard 3.5mm headphones cable that can be used when the headphones are turned on or off. The microphone cannot be used over the 3.5mm cable, however.Using the app you can personalise the noise-cancelling to take into account hair, glasses and other things that effect the seal of the ear cups, while a pressure optimiser that can determine whether you are on the ground or in the air helps when flying versus just the commute. The power button triggers pairing mode when held for several seconds from off. Photograph: Samuel Gibbs/The Guardian The case is clearly different, though. With the WH-1000XM5, it’s obvious where the headphones are supposed to sit, whereas with the WH-1000XM4 case you have to contort the headset to stow them away. But what’s probably more noteworthy about the WH-1000XM5 case is that when you have your headphones out, the material bends in a way that flattens it out and saves space.
