Not trying to undermine Sony as a manufacturer of other headphones, the WF-XB700 buds are particularly ideal during high-energy activities. As such, you will benefit from their super bass capability, which will keep you going during your fitness or running routines.


While looking for the best audio companion, sound quality is probably the first thing you will check before any other feature. Fortunately, these Sony headphones come packed with deep, punchy sound for clear low-end sound. In particular, these hybrid silicone rubber earbuds are ideal when engaged in high adrenaline activities such as runs. This preferential use is linked to its emphasis on low-end sound quality that brings out the best bass in any upbeat song.

As a result, the Sony WF-XB700 Extra Bass wireless headphones make it enjoyable to listen to that extra bass while running. Even at 50% volume, you will experience the deep, punchy extra bass sound. Subsequently, you will probably not find the punchy sound to be exactly calming while relaxing or working.

Even though you might not enjoy the full sound balance, especially in high notes, you will be able to enjoy your upbeat songs with the extra bass for deep, punchy sound output. No wonder the deep, punchy extra bass will inspire more adrenaline, making your runs more effortless.

Besides their punchy low-end sound, these WF-XB700 extra bass earbuds offer long-lasting sound output with consistent and reliable noise cancellation. Specifically, the silicone rubber around the earbuds helps keep out outside noise, thus preserving the full extra bass for deep punchy outputs. Also, the low-end sound profile of the WF-XB700 headphones helps keep out the low rumbles and noise from the environment.

Even though some might find this audio set to lack clarity in high notes, it is still adequate for true wireless earbuds. Again, the WF-XB700 earbuds are ideal when engaged in high-energy activities to optimize their deep, punchy audio quality.


To ensure you conveniently enjoy the extra bass to the fullest, these alternatives to headphones work through Bluetooth wireless technology. This truly wireless design ensures that you don't face the inconvenience of entangled wires, as is the case with previous headphone models. Notably, this wireless design with Bluetooth connectivity works through a Bluetooth chip that ensures that sound is simultaneously and equally transmitted to both earbuds.

How to Pair the Sony WF-XB700 Wireless Earbuds

These true wireless earbuds apply standard Bluetooth connectivity. These earbuds automatically enter Bluetooth pairing mode if you are the first owner and user. From this onset, ensure that the Bluetooth of the source device is switched on for visibility of the WF-XB700 earbuds.

Luckily, these earbuds lack the NFC connectivity mode, which can be a letdown compared to Bluetooth wireless technology. However, this design with Bluetooth wireless connectivity can get complicated when pairing to a second device. Please note, this premise doesn't imply that these earbuds can connect to two devices at a go but rather connecting to a second source device. To help you with this connection, here are simple steps to follow:

  • First, disconnect these earbuds from your primary/initial source device.
  • Then, hold down buttons on both buds for nearly seven seconds.
  • Subsequently, you will hear a voice notification for Bluetooth pairing and then proceed to the Bluetooth settings for your second source device.
  • Proceed and tap on the 'WF-XB700' device under the Bluetooth settings in your additional device.

Sounds easy, right? However, without knowing this procedure, you might be stuck with only one source device for the longest time. Across the entire Bluetooth connection process, you will observe that these earbuds aren't smart to allow for auto-switching across source devices. At all times, you will have to engage in the manual process of connecting and disconnecting, and to some, this might turn out to be annoying.

As such, some users have complained about losing control on which device to connect to, with the manual reconnecting method not working, leaving this set to connect to the device they choose. This premise can be a bit of a bummer compared to other competing models that come with fancy and seamless connectivity across different devices. Nonetheless, not to underplay the outstanding extra bass feature, this set can serve you seamlessly if they remain connected to the same initial source device.

How’s the Bluetooth Connection Strength?

Remaining truly wireless, these Sony Extra Bass buds present a stable and reliable Bluetooth connectivity. This truly wireless design makes use of an antenna design that optimizes connection to a source device, thus ensuring a stable connection without stutters or skips. As a result, this truly wireless headphone design with Bluetooth wireless connectivity promises outstanding listening even when making movements.

Additionally, the wireless design with Bluetooth provides remarkable outcomes with different devices across iOS, android and windows operating systems. You won't worry about audio sync hiccups with these earbuds, especially while watching YouTube content.

It is also noteworthy that these earbuds only support SBC and AAC Bluetooth codecs, in case you expected this set to come with LDAC codec. Overall, always ensure that your source device and these wireless technology headphones remain within connection proximity for optimal sound output.

Microphone Performance of the Sony Extra Bass Earbuds

The WF-XB700 true wireless earbuds offer an adequate built-in microphone performance. Even though these small alternatives aren't as clear as traditional headphones with extended microphones, they will still serve the purpose. While connected to a call, it is possible for a person to tell that you are not speaking from a phone, but they will still hear you but as though far from your phone.

Therefore, even though the voice is not loud enough, these earbuds will conveniently enable easy hands-free calling while you are engaged, thanks to its frequency response. If you are running, you don't have to stop and reach for your phone from your pocket.

Battery Life

Staying true to its wireless nature, the Sony Extra Bass earbuds offer a relatively adequate battery life. While working with a single full-charge mode, the manufacturer claims it can last up to nine hours of continuous music playback. Nonetheless, some users have indicated while working at full bass, they have only managed to get 6 hours 30 minutes of charge before powering off. Even so, that is still adequate to get you through your running or workout routine.

The trick with these earbuds is ensuring you store them in their handy charging case when you're not using them. Working with the manufacturer's estimate, you will double on the 9-hour battery life, total 18hr while using its charging case. However, you can still invest in other models like the PowerBeats Pro earbuds for practically long hours of audio output. Eventually, the battery life of the WF-XB700 ensures this set remains highly portable.


We have already mentioned the use of a charging case in the context of getting those extra hours of consistent playback. However, the charging case is only designed to provide one extra full charge. This feature might sound like a dealbreaker but thinking about it, an extra battery life, total 18hr charge, is more than enough for a single day.

Besides the long battery life, you will also get to enjoy the quick charging of these Sony wireless headphones. Specifically, you only need to charge these earbuds for 10 minutes to get 60 minutes of continuous music.

Besides ensuring you enjoy extra music playback hours, the WF-XB700 handy charging case also ensures you safely store your earbuds.

So first, you get the impression of small and compact storage even before you know it's also a charging port. However, some users have described the WF-XB700 bud case to have a cheap build compared to other models in the market like the AirPods Pro or WF-1000xm3. Even so, it's adequate at its given price.

Still, on the WF-XB700 case, it utilizes resistance and tension to remain shut, unlike other models that apply magnetism to keep earbuds in place and snap shut. However, this method of keeping it shut can be hectic, especially when opening it, most times requiring two hands to open. Nonetheless, the lid on this case is translucent, ensuring you can keep monitoring your earbuds as they charge. In essence, you can see small LED lights as indicators of successful charging.

Finally, the WF-XB700 true wireless earbuds snap perfectly into place for charging, thanks to a strong magnetic feature that also keeps the headphone securely in place. Even so, you should avoid tough drops.
