The Sony INZONE Buds Truly Wireless are earbuds designed with gaming use in mind. Sony have manufactured a number of gaming headsets under the INZONE name, but this is the first pair of earbuds they've released as part of the line. They feature active noise cancelling (ANC) and spatial sound technologies and a purported 12-hour battery life. While they use the same drivers as the Sony WF1000-XM5 Truly Wireless, the manufacturer claims they have a unique design that reduces ear contact for a more comfortable fit. They also support Bluetooth via LE audio and use the LC3 codec for lower energy and lower bandwidth audio data transmission.
Our Verdict
The Sony INZONE Buds are good for sports and fitness, even though they aren't designed with this use in mind. They're portable, lightweight, and decently comfortable. However, if you don't have a device that supports Bluetooth LE, you'll need to bring the wireless transmitter and a source device with a USB-C port.
- Robust customization options via INZONE Hub.
- Great full range noise isolation performance.
- Lightweight and portable design.
- Consistent audio delivery.
- Loose fit won't be for everyone.
- Only support Bluetooth LE Audio.
The Sony INZONE Buds are good for commuting and travel. Their noise isolation performance is sufficient for blocking out most external sound, but some noise, especially bass frequency noises like engine rumble, will find its way into your audio. You'll also need to use the buds' included wireless transmitter to connect them unless you own a device that supports Bluetooth LE and the LC3 codec. Nevertheless, these buds are portable, decently comfortable, and their solid battery life will get you through everything from a daily commute to a longer journey.
- Very good battery life.
- Great full range noise isolation performance.
- Lightweight and portable design.
- Consistent audio delivery.
- Loose fit won't be for everyone.
The Sony INZONE Buds are decent for office work. Their ANC performance does a good job of blocking out background conversations and office chatter, and their battery life performance is enough to get you through even the longest work days. Their mic also captures speech effectively, though it will struggle in exceptionally noisy environments, causing your voice to drop out at times. That said, you'll need to use the wireless transmitter to connect them unless you own a device that supports Bluetooth LE audio. Plus, people used to buds that create an in-ear seal might not like their unique, loose fit.

- Only support Bluetooth LE Audio.
The Sony INZONE Buds are a decent choice for wireless gaming. Their dedicated transmitter offers low-latency gaming performance on PCs and PlayStation consoles. That said, their loose fit takes some getting used to, but combined with their very good battery life performance, these buds can get you through some marathon gaming sessions. While the relative de-emphasis in the low-bass means explosions sound less vivid, fans of first-person shooters may prefer their boosted high-bass response, which brings out footsteps. If you play mobile games, they often have app support as well, but you'll need to check your device's capabilities. Still, you can always fall back on the transmitter if your phone doesn't support Bluetooth LE and LC3.
- Very good battery life.
- Robust customization options via INZONE Hub.
- Consistent audio delivery.
- Loose fit won't be for everyone.
- Poor passive soundstage.
The Sony INZONE Buds are truly wireless buds and can't be used wired.
The Sony INZONE Buds have decent audio reproduction accuracy. In objective metrics like stereo mismatch and harmonic distortion, the earbuds exhibit no issues that affect regular use. That said, their frequency response fluctuates relative to their warm sound signature, particularly in the treble, rendering sibilants alternately dull or piercing as neighboring frequencies are de-emphasized relative to one another. The earbuds' particular brand of warmth also primarily emphasizes mid- and high-bass frequencies, which can affect vocal and instrumental reproduction by masking their fundamental frequencies.
- Consistent audio delivery.
The Sony INZONE Buds have excellent noise isolation. They attenuate treble frequencies most effectively, effectively reducing the whirr of high RPM PC fans, but they aren't the greatest in the mid-range. While they'll reduce background chatter in shared spaces, you'll still hear loud housemates or car horns on a busy road. On the plus side, the headphones don't leak much audio, so most people sitting beside you won't hear your favorite French Canadian Twitch streamer crashing out.
- Consistent audio delivery.
The Sony INZONE Buds have an okay microphone system. It captures speech intelligibly, but your voice won't sound as natural as it would with a dedicated desktop mic. And while the system deals with moderate background noise fairly well, it's easily overwhelmed by loud background noise, causing your voice to drop out on calls and recordings.
- Consistent audio delivery.
The Sony INZONE Buds have excellent frequency response consistency. Provided you have a good seal, the earbuds will deliver consistent audio between wears, though individual ear canal morphology will inevitably result in varying treble perception.
- Consistent audio delivery.

Popular Headphones Comparisons
The Sony INZONE Buds are Sony's first wireless earbuds designed specifically with gaming in mind. They're manufactured by Sony Electronics, as opposed to their PlayStation subsidiary. While they use the same drivers as the Sony WF-1000XM5 Truly Wireless, some key differences in features make them more suited to gaming. Like the Razer Hammerhead Pro HyperSpeed True Wireless, they have a wireless transmitter for a low-latency gaming experience with PCs and PlayStation consoles. They also have a fit that minimizes contact with your skin, so you can game all day without ear fatigue. However, their noise isolation performance isn't as exceptional as the WF-1000XM5.

The Sony INZONE Buds Truly Wireless and the SteelSeries Arctis GameBuds have different strengths and limitations that will influence your choice. The Sony have a longer continuous battery life, they work well with PlayStation and PCs, and they have better ANC and mic noise handling than the SteelSeries. However, the SteelSeries are a bit more flexible when it comes to Bluetooth codec support. Even though the SBC codec isn't exactly high-quality, most devices can support it compared the limited compatibility of the LC3 codec on the Sony. The SteelSeries feel more comfortable with better controls and an IP55 rating, too, though they only come in an Xbox variant. Otherwise, both support wireless USB dongles and low-latency audio.
The Sony INZONE Buds Truly Wireless are better for most uses than the Sony PULSE Explore Truly Wireless. The INZONE have a longer battery life, a better mic performance, and a better noise isolation performance, thanks to their ANC feature. They also include a dedicated app with sound customization features. On the other hand, the PULSE support more common Bluetooth codecs (SBC and AAC), so you can use their dongle to connect with PlayStation consoles and stream audio from your phone simultaneously.
If you primarily want Bluetooth earbuds with a wireless dongle, the ASUS ROG Cetra True Wireless SpeedNova are better for most people. The Sony INZONE Buds Truly Wireless are hampered by their limited Bluetooth connectivity, only supporting LE Audio via the LC3 codec, which not every device can use. However, you can use their USB-C dongle for a low-latency connection. The ASUS support a greater variety of devices with a wider net of standard Bluetooth codecs and a wireless dongle. The Sony are more geared towards PC and console gaming with dedicated support, a graphic EQ, and a more advanced virtual surround sound. Their sound profile is more balanced, too. The ASUS have slightly more effective noise isolation in common scenarios, but their battery life isn't as long as the Sony.
The Razer Hammerhead Pro HyperSpeed True Wireless are better earbuds for wireless gaming than the Sony INZONE Buds Truly Wireless. While both buds have similarly comfortable fits and lightweight, portable designs, the Razer have a more balanced sound profile, which you may prefer. They also have better mic performance and better Bluetooth connectivity options as they use the SBC codec by default. In contrast, the Sony only use LE audio, which is newer and has limited compatibility. However, the Sony have a considerably longer battery life.
