As for the rest of the sound spectrum, the mids just aren't there. Sony claims the bass doesn't overpower the mids but the mids weren't good enough to begin with. Even when you use the app and bring down the bass, the mids are still hard to hear and you have to increase the volume to hear them better. The sound features include various surround effects, such as arena, club, outdoor stage and concert hall. You can also adjust the bass level and also the position of the sound around your head. The exact purpose of the latter has always deluded me but it's a cool effect nonetheless. There's also DSEE, which is Sony's upsampling feature for improving the sound of compressed audio files but either I don't have sufficiently compressed files or the feature doesn't do much because it's impossible to tell the difference between it being on or off. Applicable headphones are WH-1000XM3, WF-1000XM3, WI-1000XM2, WH-1000XM4, WF-1000XM4, WH-XB900N, WH-XB700, WH-H810, WH-H910N, WF-C500, WH-XB910N.

However, in the past, Extra Bass headphones were rather disappointing. Sony would tend to turn the bass up till it broke the dial, which resulted in a horribly bloated sound where it was hard to hear anything but the bass. With the XB700, there seems to be an attempt at some semblance of a balanced sound apart from the advertised extra bass. The headphones are made almost entirely out of plastic with a matte, sandblasted finish on the ear cups and headband. While not necessarily cheap-looking, it doesn't really hide the fact that this is an inexpensive pair of headphones. They are also very lightweight due to the plastic construction. Understandably, everyone will have different ears and tolerance for pain and some might not find an issue with the design at all. But if you are someone who, like me, has experience with discomfort with supra-aural style of headphones then you know to avoid this one.

How long does the battery of the Sony WF-XB700 last?

Once Bluetooth devices are paired, there is no need to pair them again, except in the following cases:

Unfortunately there isn’t any fancy way to connect to these in the same way that there is for other popular models. You won’t even find NFC here which I find to be a bit of a bummer as I still think it’s a seriously underrated way to pair two devices together (if you’re on Android at least). To initially pair, all you have to do is take the earbuds out of the case for the first time and they will automatically enter pairing mode. From there, just look into the Bluetooth settings of your source device for “WF-XB700” and tap it to connect. If you’re already connected to a device and want to pair a second device, then there’s a bit more of a process that you’ll need to go through. Finally, moving on to the performance, the XB700 deliver what they say on the tin. If you enjoy overly exuberant bass, these really are the headphones for you. Once you hear the “Bluetooth pairing” notification go to the Bluetooth settings son your secondary device. The pairing process with the headphones is fairly simple. You can either press and hold down the power button to enter pairing mode or use NFC to pair your Android phone. When registering a device (pairing), [WH-XB700], [LE_WH-XB700], or both may be displayed on the connecting device. When both or [WH-XB700] is displayed, select [WH-XB700]; when [LE_WH-XB700] is displayed, select [LE_WH-XB700].The XB700 are a fairly basic pair of wireless headphones, and you can tell that from their design. They have a very minimal, monochromatic design without any flashy elements or any design flair of any sort. The XB700 has a V-shaped sound signature, which means while the mids are recessed, the highs, like the bass, are boosted. Here, again, things aren't too aggressive and while the upper-mids and lower-highs are a bit hot, it does sound nice and fakes the impression of having extra detail and clarity in the sound. The upper highs do get a bit sibilant at times and oddly enough, they get even more sibilant if you reduce the bass through the app. All of the pairing information is deleted. In this case, delete the pairing information for the headset from the device and then pair them again. The XB700 also, thankfully, charge over USB-C. Sony includes a cable in the box but at 20cm long it feels rather useless. The headphones do have a fast charging feature, where they can provide 90 minutes of usage after just 10 minutes of charge. A full charge, however, takes a lengthy 4 hours.
