Sony WF-SP700N wireless headphones review

Sony’s fully wireless WF-SP700N are great for bass, light on battery

They fit well and sound great, but the Sony WF-SP700N fall short on battery life, and that’s a deal breaker.

DT Editors' Rating

It wasn’t until very recently in the history of fully wireless headphones that we actually preferred a pair over banded-wireless headphones for daily use. The first generation of totally cord-free in-ears were lauded if they could simply maintain a connection to your phone — but times have changed. The bar has been raised considerably over the last year or so as companies like Jabra, Bragi and (industry leader) Apple presented fully wireless earphones that deliver great connection, decent battery life, and solid audio performance to boot.

With advanced features like active noise-canceling, custom equalization, and sweat-proofing, Sony’s fully wireless WF-SP700N look to join the top echelon of true wireless headphones. Unfortunately, though, while the SP700N sound great and fit quite well, a few nagging issues keep them from edging out our favorite fully wireless earphones.

Out of the box

The WF-SP700N come in a small box with the headphones inside a rounded charging case, tucked beneath an easy-access lid that slides open with a flick of your thumb. Riding along are three color-coded sets of silicone eartips, a pair of sport fins, and a micro USB charging cable.

Features and Design

The SP700N offer a stylish finish, but their bulbous size is reminiscent of the once-popular Bluetooth headsets of yesteryear, commonly worn by fast-talking yuppies in convertibles. (In fact, they can even be used individually as single Bluetooth earpieces.) Curvy, lima-bean shaped headphones that hang down to your cheek, the SP700N grab people’s attention with their sheer size, even in our review units’ subdued silver-and-white colorway (they can also be had in pink, yellow, and black).

Once you put them in you’ll quickly forget you’re wearing them at all.

While some might be after a flashy set of in-ears to show off, these aren’t that; we honestly felt we looked like that same yuppie — now middle-aged — driving the same convertible and wearing the same headset in 2018.

Once you put them in you’ll quickly forget about how bulky they look to the outside world; in fact, you’ll forget you’re wearing them at all. The soft silicone tips and hyper-ergonomic sport fins combine to make the SP700N among the most comfortable fully wireless in-ears we’ve had the pleasure of wearing, with virtually no ear fatigue over hours of steady listening. They are also quite light and secure, allowing us to head bang to our favorite metal or run a fast-paced mile without so much as a single readjustment.

A small plastic button on the outside of the right earpiece allows you to play or pause music, and the same button on the left allows you to toggle the headphones’ built-in active noise cancellation, or pipe in a bit of the outside world via Sony’s ambient sound mode. That feature is similar to those we’ve seen from the Jabra Elite Active 65t and several others. Sony’s version comes in handy during bike rides and runs — situations where fully wireless headphones have a major advantage over more traditional models.

Speaking of working out, the SP700N are IPX4 rated, which means the headphones are protected from splashes and light rain. That’s not quite as robust as the protection of said Jabra Elite Active 65t, but outdoes Apple’s AirPods and many other models not specifically designed for workouts.

Whatever you’re doing with the headphones, you’ll want it to be relatively brief, and that’s really the biggest flaw in the SP700N: Their three hours of playback per charge is well below the standard five hours set by Apple and followed by all our favorite models. As we know from experience, anything below four or five hours will leave your earbuds shutting down far too often, offsetting the convenience factor.

The SP700N’s included charging case does add two full charges, but at a total of nine hours of juice, they lag significantly behind the 15 and 25 total hours offered by Jabra and Apple, respectively.


Setting up the Sony SP700N is a breeze, thanks to a sturdy Bluetooth 4.1 connection and voice instructions in the headphones. Simply pull them out of the case and find and pair them to your device. They also feature near-field communication (NFC) connection, so you can touch pair them with supported devices.

The connection never dropped, even with our phone in a back pocket or backpack, and we were very satisfied with how quickly the headphones reconnected to source devices when we pulled them back out of their charging case.

Audio performance

As you might expect from Sony, one place the SP700N really stand toe-to-toe with the best fully wireless in-ears we’ve tested is their audio quality.

That starts with their spectacular bass response. When listening to modern hip-hop from Kendrick Lamar, A$AP Rocky, and others, we were shocked with their ability to deliver the punchy, club-like low end that we wanted without overwhelming what was happening up top. That makes them very lively to listen to overall, and an absolute joy with any beat-driven tunes.

Sound quality stands toe-to-toe with the best fully wireless in-ears we’ve tested.

Even when listening to more acoustic-driven music from singer/songwriters like Elliott Smith and Ryan Adams we never felt like the lower frequencies of acoustic guitar sounded heavy or overwhelming. In fact, the SP700N’s high-end shimmer is always very pleasant, allowing the midrange of the vocals to tuck in beneath it with casual ease.

Sony also earns brownie points in terms of allowing listeners to customize the sound signature of the headphones to their liking. The Sony Headphones Connect app offers an EQ feature, allowing you to change the signature of the in-ears to your liking. We liked the factory tuning so much we left it virtually untouched, though we did roll off a touch of bass when listening to some vintage jazz recordings.

In general, the SP700N rival wired in-ears we’ve tested at or around the $100 mark, and at this stage that’s an impressive feat for a set of fully wireless headphones.

While we loved using the ambient sound input when working out, the noise-canceling tech seemed like an afterthought — unusual from a company whose WH-1000xM2 over-ears rank as our favorite noise-canceling option on the market. The SP700N’s noise cancelling does cut out some ambient noise, but it also comes with a noticeable high-end hiss, and it just doesn’t do enough to make it a compelling feature. We were also able to eek out a few more precious minutes from the miniscule battery with noise canceling off.

Warranty information

Sony offers a one-year limited warranty on defects from the factory.

Our Take

The WF-SP700N are comfortable, well-functioning fully wireless in-ears, but short battery life and an oversized design keeps them off our list.

Is there a better alternative?

Yes. The Jabra Elite Active 65t offers longer battery life, more balanced sound, and an even more life-proof design, and costs the same amount of money. Jabra’s original 65t – which offers nearly the same package, costs even less, as do Apple’s robust and popular AirPods.

How long will they last?

Sony has a history of manufacturing extremely high quality products, so we have no reason to believe the WF-SP700N won’t last through years of steady use. Unfortunately, their battery life is already behind the times, and it won’t be getting any better with age.

Should you buy them?

If you put comfort and quality bass response above all else, you might consider them. Otherwise, no. The WF-SP700N are totally decent (and extremely comfortable) fully wireless in-ears, but they simply can’t compete with similarly priced competitors in terms of battery life, and their biggest outstanding feature – noise canceling – just isn’t worth the effort.
