The Sony WF-XB700 are good-sounding pair of earphones. The sound has obviously been designed to accentuate the bass but the rest of the audio spectrum is surprisingly well-balanced. This is a departure from what we normally see on Sony Extra Bass Headphones that feature a lop-sided sound signature that makes it hard to notice anything else in the sound other than the bass.

Starting with the low-end, the WF-XB700 have perhaps one of the most restrained bass boosts I’ve heard in Sony’s history. Not shy of going all-out, Sony’s Extra Bass products often feature a bombastic bottom-end that overwhelms your eardrums. The WF-XB700 takes a more tasteful approach here, with a measured twist of the volume dial across the entire bass range. We are talking not much more than about 5dB boost across the range.

What this does is give a nice little kick to the low-end without blowing it out of proportions. Drums and other percussion instruments have a deeper thump to them without losing their essence. Electronic bass drops are just that bit more enjoyable without blowing your ears. There is a bit of rumble and boominess as a result of boosting frequencies that weren’t meant to be boosted but it isn’t too distracting here and depending on the content (movies, games) may even be enjoyable.

Software and features

The WF-XB700 are not compatible with Sony’s Headphone Connect app. This means you can’t customize the sound, update the firmware or access any additional functions. You are pretty much limited to what you get out of the box and whatever your connected phone has to offer.

The WF-XB700 support Bluetooth 5.0, however, there is no multi-device pairing support. In terms of codecs, you are limited to SBC and AAC but as I often say in these reviews, what codecs you have has less of an impact on audio quality than how the codec is implemented and how the audio is coded, decoded and then processed.

The WF-XB700 lack NFC so any pairing has to be done manually. Out of the box, they are already in pairing mode so you are good to go. If you need to repair them, just press and hold buttons on both the earphones for seven seconds to put them into pairing mode.

The odd thing with the WF-XB700 is that announcements regarding connectivity and pairing often happen in just the left earphone even when both are in use. Both earphones will announce their individual battery status but for everything else that concerns them both, the announcement only happens in one ear. Not sure what the logic behind that is.


The WF-XB700 have a claimed continuous battery life of 9 hours. The case provides one additional charge for another 9 hours of use, so a combined 18 hours of battery life.

During my usual battery drain test, the WF-XB700 went on for about 9 and a half hours of continuous playback. That’s much longer than most truly wireless earphones in its class, including the Galaxy Buds and Apple AirPods, and close to the more expensive Galaxy Buds+. The combined 18 hours might not seem that impressive compared to other models but the WF-XB700 offers more of it continuously rather than splitting it up over multiple charges.

Speaking of charging, this is something that takes a while on the WF-XB700. Charging the earphones takes 2.5 hours and charging the case itself takes 3 hours. The earphones also get fairly warm when they are charging within the case and putting them on like that isn’t particularly pleasant.

Sony has a fast charge solution of sorts, which provides an hour of battery life after just 10 minutes in the case. This does work as advertised and the earphones lasted a fair bit longer than an hour in my test. This should be fine for most situations but be prepared for a long wait for a full charge.
