The Corsair HS70 Bluetooth are wired gaming headphones that support Bluetooth. Thanks to their design, you can receive separate audio from your wireless device and console at the same time. They're comfortable, have a long-lasting continuous battery life, and are compatible with Corsair's iCUE software if you like to customize their excited sound profile. That said, their mic has some distortion, and the headphones don't really isolate noise around you. Still, they offer a good wired gaming experience that's also versatile enough for casual use.

Our Verdict

6.6 Mixed Usage

The Corsair HS70 Bluetooth are alright for mixed use. They're comfortable, well-built, and offer 24 hours of continuous battery life, making them well-suited for long commutes or days at the office. However, they struggle to isolate noise around you and can also fall off your head if you're exercising. Their excited sound profile may also not be suitable for neutral sound right out-of-the-box. That said, they're good for wired gaming as they have companion software so you can customize their sound, and their boom mic has a good overall performance.

Pros
  • Comfortable fit.
  • iCUE companion software with graphic EQ and presets.
Cons
  • Inconsistent bass and treble delivery.
  • Poor noise isolation performance.
6.6 Neutral Sound

The Corsair HS70 Bluetooth are fair for neutral sound. They have a very excited v-shaped sound profile that delivers extra boom and brightness. However, some users may find they sound muddy and piercing. They also have inconsistent bass and treble delivery. If you prefer a different sound profile, their companion software offers a graphic EQ and presets to help tweak their sound.

Pros
  • Comfortable fit.
  • iCUE companion software with graphic EQ and presets.
Cons
  • Inconsistent bass and treble delivery.
  • Poor noise isolation performance.
6.4 Commute/Travel

The Corsair HS70 Bluetooth are acceptable for commute and travel. They're comfortable, support Bluetooth so you can listen to audio from a smartphone, and have over 24 hours of continuous battery life. However, they're also bulky, which can make them hard to take with you on-the-go, and they really struggle to block out bass-range noise like bus or plane engines.

Pros
  • Comfortable fit.
Cons
  • Poor noise isolation performance.
6.9 Sports/Fitness

The Corsair HS70 Bluetooth are okay for sports and fitness. While they have a comfortable fit and can be used wirelessly thanks to their Bluetooth support, they're bulky and aren't really designed for this purpose. They can move around your head during moderate physical exercise and they also don't have an IP rating for dust or water resistance, although we don't currently test for this.

Pros
  • Comfortable fit.
Cons
  • No IP rating.
6.5 Office

The Corsair HS70 Bluetooth are adequate for office use. They're comfortable enough to use throughout your shift and their 24-hour battery life can last for a few days before they need to be recharged again. However, they really struggle to block out noise like ambient chatter. They also leak audio, so if you're listening to music at a high volume, those around you can hear it.

Pros
  • Comfortable fit.
Cons
  • Poor noise isolation performance.
5.8 Wireless Gaming

The Corsair HS70 Bluetooth aren't compatible with Xbox One or PS4. While they can be used with Bluetooth-enabled PCs, their latency is likely too high to be suitable for gaming.

7.5 Wired Gaming

The Corsair HS70 Bluetooth are good for wired gaming. These comfortable headphones have full audio and microphone support via their 1/8" TRRS cable and wired USB connections. They also support Bluetooth so that you can teamchat via your smartphone while also receiving audio from consoles. They're compatible with iCUE software so you can customize their sound and their microphone offers good overall performance.

Pros
  • Comfortable fit.
  • iCUE companion software with graphic EQ and presets.
Cons
  • No channel mixing controls.
6.9 Phone Calls

The Corsair HS70 Bluetooth are alright for phone calls. Their removable boom microphone does a decent job of recording your voice, but speech may have some distortion present. That said, it does an excellent job of separating your voice from loud environments. If you're taking calls, these headphones are best suited for quiet environments as they struggle to isolate noise around you.

Pros
  • Comfortable fit.
Cons
  • Poor noise isolation performance.
  • 6.6 Mixed Usage
  • 6.6 Neutral Sound
  • 6.4 Commute/Travel

Style

The Corsair HS70 Bluetooth look very similar to the Corsair HS70 Wireless but have an overall more muted and sleek look due to their all-black design. Thanks to this detailing and detachable boom microphone, they can easily transition into casual use.

The Corsair HS70 Bluetooth have a comfortable fit. They don't clamp too tightly on your head and the ear cups, as well as the headband, are well-padded. They should be comfortable for long gaming sessions without becoming too fatiguing. However, the swiveling hinges don't have a wide range of motion.

Additional Controls Bluetooth + Multi function

The Corsair HS70 Bluetooth have decent controls. On the left ear cup is a volume control wheel that stops at min/max volume. There's also a mic mute button that feels clicky and has a chime to let you know when it's on or off. However, there's no way to know if the mic is muted or not if you're already wearing the headset, although when you connect to a PC via USB for the first time, a voice prompt tells you its status. The right ear cup has a power button that also acts as a multi-function button. When connected to Bluetooth, a single press answers and ends calls as well as plays and pauses audio. A double-press skips the track forward and a triple-press returns to the previous track. However, you can accidentally play or pause when trying to register a double-press.

The Corsair HS70 Bluetooth aren't very portable. They're bulky and the ear cups can't swivel to lay flat to make them more compact. Luckily, you can remove their boom microphone when you're on-the-go. They also support Bluetooth, so you can connect your smartphone to them without a cable.

Build Quality

The Corsair HS70 Bluetooth have a great build quality. Just like the Corsair HS70 Wireless and Corsair HS75 XB WIRELESS Gaming Headset, they're made of plastic with metal hinges and faux leather padding. Overall, they feel sturdy, although the cloth lining inside the ear cups may be vulnerable to rips or tears over time.

Design
Stability

The Corsair HS70 Bluetooth are decently stable. Their fit is tight enough to stay on your head while gaming, but they can fall off during moderate physical activity. Thanks to their Bluetooth support, you can use them wirelessly to eliminate the risk of an audio cable snagging on something while you move.

The Corsair HS70 Bluetooth have an excited, v-shaped sound profile. They deliver punch and boom that can help bring out sound effects in action-packed video games. Their bright treble can also make vocals and lead instruments sparkle. That said, some users may find that they sound muddy and piercing. Luckily, their companion software has a graphic EQ and presets so that you can tweak their sound to your liking.

The Corsair HS70 Bluetooth have great mid-range accuracy. Although the left and right drivers are slightly mismatched, the low-mids are overemphasized, which sounds muddy or cluttered. However, the mid-mid and high-mid are fairly flat and balanced, which results in clear as well as present vocals and lead instruments.

The Corsair HS70 Bluetooth have passable treble accuracy. It's overemphasized across the range, so the upper harmonics of vocals and lead instruments sound bright and a bit harsh. Sibilants like S and T sounds are found in the mid-treble range and they have a piercing quality to them.

The Corsair HS70 Bluetooth have alright peaks and dips performance. There's a peak in the high-bass, so mixes can sound muddy and boomy. The mismatch between drivers in the mid-range thins out vocals and instruments in the right driver while nudging these same instruments to the back of the mix in the left driver. There's also a dip in the high-mids, which weakens vocals and lead instruments. The uneven low-treble gives the upper harmonics of these instruments both a bright and veiled sound. Finally, the steep peak in the mid-treble makes sibilants like cymbals piercing.

The imaging is great. The weighted group delay falls below the audibility threshold, resulting in tight bass and transparent treble. The left and right drivers are also well-matched in amplitude and phase response, resulting in a stable stereo image. While there's a small amount of frequency mismatch, it's fairly minor, and the localization of objects like voices or footsteps should be accurately placed within the stereo image. That said, these results are only valid for our unit, and your experience may vary.

The Corsair HS70 Bluetooth's passive soundstage is alright. It's perceived as wide and coming from out in front of you, rather than inside your head. However, it also seems slightly unnatural, and due to their closed-back design won't sound as spacious as open-back headphones.

The Corsair HS70 Bluetooth's weighted harmonic distortion performance is decent. There's a small peak in the treble range at regular volumes. However, it can be hard to hear this with real-life content. That said, the range falls within good levels at max volume, which results in clean and pure audio reproduction.

The Corsair HS70 Bluetooth's noise isolation performance is poor. They don't block out almost any bass-range noise like bus or plane engines. They also struggle to cut down mid-range sounds like ambient chatter. However, they can reduce a lot of higher-pitched noise like the hum of an AC unit.

The Corsair HS70 Bluetooth have decent Bluetooth connectivity. While you can't pair them with more than one device at a time and they don't support NFC pairing, they have low latency on Android and iOS, which is handy if you like to chat with teammates while you game. However, their latency on PC is much higher, so they may not be suitable for gaming or streaming videos. That said, apps and devices compensate differently for latency, so your experience may vary in the real world.

Compared To Other Headphones

The Corsair HS70 Bluetooth are wired headphones that support Bluetooth, making them a bit more versatile than the Corsair HS70 Wireless. They're comfortable, well-built, compatible with iCUE software, and come with both a 1/8" TRRS and wired USB cable. However, they lack channel mixing controls, which some gamers may find disappointing. Check out our recommendations for the best gaming headsets, the best PS4 gaming headsets, and the best Xbox One gaming headsets.

Corsair HS70 Wireless

The Corsair HS70 Wireless and the Corsair HS70 Bluetooth have different strengths and depending on your usage, you may prefer one over the other. The Wireless are better for wireless gaming as they use a wireless USB dongle that has low latency. While their battery life doesn't last as long as the Bluetooth, they have an auto-off timer. However, the Bluetooth are better for wired gaming as they can be used with either their 1/8" TRRS or wired USB dongle cable. They also support Bluetooth, which makes them a little more versatile.

Beats Solo Pro Wireless

The Beats Solo Pro Wireless and the Corsair HS70 Bluetooth have different strengths and depending on your needs, you may prefer one over the other. The Beats are better for mixed use, as they have a more neutral sound profile suitable for a variety of audio content. They also have a great active noise cancelling feature that can help block out ambient sound during your commute or workday. However, the Corsair are designed for gaming, even though their wireless design ensures that they can be used more casually too. They have a better-performing boom mic and a companion app so you can tweak their sound to your liking.

Corsair HS60

The Corsair HS70 Bluetooth are more versatile than the Corsair HS60. While both headphones are comfortable and well-built, the HS70 Bluetooth have better controls, support Bluetooth, and offer 24 hours of continuous battery life. They also have a slightly better performing boom mic.

SteelSeries Arctis 3 2019 Edition Wireless

The SteelSeries Arctis 3 2019 Edition Wireless are slightly better headphones than the Corsair HS70 Bluetooth. The SteelSeries have a more neutral sound profile right out-of-the-box, and their overall mic performance is better too. They also offer a longer continuous battery life. However, the Corsair are better-built and are compatible with iCUE companion software which offers a graphic EQ plus presets.

HyperX Cloud Alpha

The Corsair HS70 Bluetooth and the HyperX Cloud Alpha are similarly-performing gaming headphones, so depending on your preferences, you may prefer one over the other.

However, the Corsair support Bluetooth and have around 24 hours of playback time.
