The LucidSound LS31 is a good wireless gaming headset with plenty of control options but takes some time to get used to. It has decent audio reproduction and is comfortable for long gaming sessions. It also uses a dual microphone system for accurate recording/transmitting of your voice. Unfortunately, the headset feels quite loose on the head and doesn’t create an air-tight seal, which is important for isolating ambient noise, meaning it will be better suited for quiet environments. On the upside, the USB dongle reduces the latency to a minimal amount that you shouldn’t notice, and you’ll be able to enjoy your games from your couch thanks to their good wireless range.

The LucidSound LS31 is a decently-built headset with thick padding for good comfort during long gaming sessions. The big cups feel a bit loose on the head so the headset might fall relatively easily, but this shouldn’t be a problem during gaming. These headphones have many controls options, but it may be confusing to use, especially right out of the box. They have a detachable mic, and you can also use them wired with the included audio cable, but they might be a bit too bulky for outdoor uses. Also, they only work wirelessly with their USB dongle. 


The LucidSound LS31 is a gaming headset that doesn’t really look like one if you detach the microphone. They look like regular headphones with thick padding, but the cups do look a bit cheap due to the thin plastic. They have a metallic finish for the headframe and around the cups, which gives it a premium look, but the headset doesn’t actually feel high-end. It also only comes in a single color scheme option.

7.5 Comfort
Weight : 0.8 lbs
Clamping Force
0.9 lbs

The LS31 is a comfortable headset that you’ll be able to wear for long gaming sessions. The cups have thick padding, and the headband is well-padded too. This headset is fairly lightweight for their bulky design. Their clamping force is also low, and they feel a bit loose on the head, which some may not like. However, the stiff ear cups may make them feel a bit tighter for some.

Ease of use : Okay

Volume Control : Yes
Microphone Control : Yes

Noise Canceling Control : N/A
Additional Buttons : Presets

The LucidSound LS31 have a decent control scheme with many options, but it might be confusing to use, especially right out the box. You have a dial and a button on each cup. The left ear cup dial controls “game audio” (any audio that goes through the headphones that isn’t a third-party voice-chat app). This means it's essentially a volume dial for your games, Spotify/music apps, video players or any sound coming from your browser.
The right dial is for chat volume (controls how much you hear your friends in Discord, for example). For the buttons, one tap on the left ear cup mutes the headphones completely, game and chat audio. A single tap on the right ear cup is to mute/unmute the microphone, while a 3-second hold is for mic monitoring. However, mic monitoring, or sidetone, is controlled by the game audio dial (left), which is counter-productive since if you want to reduce your own voice, you’ll reduce game audio as well. It is also important to note that an in-game chat system counts as game audio, and not chat audio (we tested it in League of Legends, Overwatch and CS:GO). This means you won’t be able to mute your online teammates without muting game audio at the same time.
You also get an EQ button to cycle between bass, default and treble sound profiles. Some may also find the buttons very sensitive and might register unwanted actions often.

6.4 Breathability
Avg.Temp.Difference : 5.7 C

Like most over-ears and gaming headsets, the LS31 are not very breathable. Their design traps heat inside the ear cups, and you may feel a difference in temperature if you wear them for a long time. This headset won’t be ideal for sports as you’ll sweat more than usual.

5.3 Portability
L : 8.0 "
W : 7.8 "
H : 3.7 "
Volume : 231 Cu. Inches
Transmitter required : N/A

The LucidSound LS31 is a bulky over-ear headset that isn’t very portable, like most gaming headsets. However, gaming headsets usually stay in one place, and you don’t need to often travel with them. If you do need to take the LS31 on the go, the cups swivel, so it is easier to slide it in a bag.

The LucidSound LS31 don't come with a case to protect the headphones.

7.0 Build Quality

The LucidSound LS31 is a decently-built gaming headset. The headband is made of metal and feels solid, yet flexible. Unfortunately, the cups are made of thin plastic that looks a bit cheap and might be susceptible to breaking due to impacts. Also, while the hinges look to be metal, it is actually plastic with a metallic finish and won’t be very durable.

6.0 Stability

This headset is not very stable on the head. Tilting your head won’t cause much movement, but as soon as your head is moving a bit more, the cups’ weight will make them slide off. Thankfully, their wireless design eliminates the risk of a cable getting stuck on something and pulling the headset off your head. This shouldn’t be a problem during gaming sessions, but this bulky headset is definitely not made for physical activity.

 It has a powerful and relatively deep bass, a good mid-range, but an underemphasized treble. Unfortunately, the bass is quite boomy and lacks a bit of thump and rumble, while the vocals and leads are going to sound cluttered. The treble range is also uneven and will lack detail, but will also sound sharp on certain S and T sounds for some. The LS31 is suitable for bass-heavy genres, but might not be an ideal choice for vocal-centric music. 

Note: These headphones have 3 EQ presets that you can cycle through, but we measured them with the default sound profile. 

Sound Profile
6.8 Peaks/Dips
2.17 db
1.5 db
7.8 Frequency Response Consistency
Avg. Std. Deviation
0.44 dB

The LS31 has a good frequency response consistency. The treble range is quite consistent across multiple re-seats, with the maximum deviation below 10KHz being about 3dB. In the bass range, the delivery is also quite consistent across re-seats and multiple human subjects. However, we noticed that having glasses could break the seal and caused a drop of 6dB at 20Hz, which is not that audible.

7.6 Imaging
Weighted Group Delay
Weighted Amplitude Mismatch
Weighted Frequency Mismatch
Weighted Phase Mismatch

The LS31 headphones have good imaging. Their weighted group delay is 0.26, which is very good. The GD graph shows that its group delay is entirely under the audibility threshold. Additionally, the L/R drivers of our test unit were very well-matched in amplitude, phase, and frequency, ensuring accurate placement and localization of objects (voice, instruments, footsteps...) in the stereo image. However, these results are only valid for our unit, and yours may perform differently.

6.5 Soundstage
PRTF Accuracy (Std. Dev.)
2.84 dB
PRTF Size (Avg.)
5.01 dB
PRTF Distance
9.71 dB
Acoustic Space Excitation

The LucidSound LS31 have an average soundstage. Their PRTF response shows a decent amount of pinna interaction and activation, with decent accuracy. However, there is not a 10KHz notch present. Therefore, their soundstage may be perceived large, but unnatural and located inside the head.

7.5 Weighted Harmonic Distortion
WHD @ 90
WHD @ 100


The LucidSound LS31 have poor isolation performance. Their cup design makes it hard to get an air-tight seal, and a lot of noise will seep into your audio. This means they won’t be ideal for commuting and traveling and are better suited for very quiet environments. They are also a bit leaky, which will be distracting for people surrounding you if you listen to high volumes.

3.5 Noise Isolation
Isolation Audio
Overall Attenuation
-9.83 dB
0.17 dB
-2.29 dB
-27.26 dB

The noise isolation performance is sub-par. These closed-back headphones do not isolate at all in the bass and mid ranges, letting in the rumble of engines and ambient chatter around you. In the treble range, occupied by sharp sounds like S and Ts and fan noises like A/C systems, they achieve an isolation of 27dB, which is above-average.

6.6 Leakage
Leakage Audio
Overall Leakage @ 1ft
41.92 dB

The leakage performance of the LS31 is sub-par. The significant portion of their leakage is spread between 400Hz and 2KHz, which is a relatively broad range. So although their leakage won't be as full-sounding as that of open-back headphones, it'll be more noticeable than in-ears and earbuds. On the plus side, the overall level of their leakage is not too loud. With the music at 100dB SPL their leakage averages at 42dB SPL and peaks at 55dB SPL which is about the noise floor of an average office.



Detachable Boom

The LucidSound LS31 use a dual microphone system (one integrated and one boom mic). Speech recorded or transmitted with this gaming headset will sound clear and full-bodied. You’ll also be able to use it in very loud environments, like gaming conventions, and it will do a great job at separating speech from ambient noise. It should be noted that our testing was only done on the boom mic.

8.0 Recording Quality
Recorded Speech
24.13 Hz
FR Std. Dev.
0.98 dB
4695.06 Hz
Weighted THD
26.98 dB

The recording quality of the LS31's boom mic is great. LFE (low-frequency extension) is at 24Hz, which is great. This results in a recorded/transmitted speech that sounds full-bodied. The HFE (high-frequency extension) of 4.7KHz means recorded speech will be fairly detailed and present. The response between the LFE and HFE points is flat and even, so speech sounds natural. The audio playback sounds a bit distorted because we couldn't control the volume of the microphone on the test PC.

8.5 Noise Handling
Speech + Pink Noise :
Speech + Subway Noise :
35.14 dB

The boom mic of the LS31 is great at noise handling. It achieved a speech-to-noise ratio of 35dB in our SpNR test, which means it can separate speech from ambient noise to a good degree in very loud environments, like gaming conventions.


Active Features

The LucidSound LS31 is a wireless headset that provides about 17 hours of continuous playback on one charge. This should last you for a whole day and long gaming sessions. If you’re sitting close to your power source, you’ll be able to use them while charging, which is convenient. Unfortunately, this headset doesn’t have a gaming software and app to enhance your listening experiences thanks to customization options. They do however have 3 EQ modes, which you can cycle through with a button directly on the headphones.

The LS31 have a good 17-hour battery life that will last you long gaming sessions. They take about 3 hours to charge fully, but thankfully, you’ll be able to charge them while still using them. This shouldn’t be a problem for people who can sit close to their power source. Unfortunately, they don’t have any power saving feature to extend battery life if you forget to turn them off.

The LucidSound LS31 is a wireless headset but isn’t Bluetooth compatible. You can use this headset with its USB dongle on PCs and consoles. However, there is no wireless microphone support on the Xbox One. These headphones have a great wireless range that will let you game from your couch without a problem, and their dock provides a lag-less experience with very low latency.

The LS31 come with a USB dongle that you can use with PCs and consoles. However, on Xbox One, you’ll have to use a wired connection to the controller to get the mic support. Unfortunately, the dongle doesn’t have any inputs other than the Mini-TOSLINK (3.5mm/optical) input jack. You also can’t charge the headset with the dongle; you’ll have to use another micro-USB cable to do so.

Compared to other Headphones

The LucidSound LS31 is a good gaming headset that sets itself apart by its game and chat volume dials on the ear cups. It’s a comfortable headset with a great microphone for online games. It can be used wirelessly on PC and PS4, but you’ll need the audio cable connected to your Xbox One controller for mic support. If you’re an Xbox One gamer and would prefer a fully compatible wireless headset, see our recommendations for best Xbox One gaming headsets, the best wireless gaming headsets, and the best wireless headphones.

HyperX Cloud Alpha

If you really want a wireless headset for gaming, then the LucidSound LS31 is a better option than the HyperX Cloud Alpha. It is wireless and has game and voice chat channel mixing, which some gamers will appreciate. However, if you don’t want to manage a battery life and don’t mind a wired connection, the Alpha are better built, more comfortable, and have a great audio reproduction and microphone. 

SteelSeries Arctis 7 Wireless 2017

The SteelSeries Arctis 7 is a better gaming headset than the LucidSound LS31. The Arctis 7 beats the LS31 in pretty much every category, other than wireless range, but only by a few feet when the source is obstructed by walls, which should rarely happen when gaming. The Arctis 7 is one of the best gaming headsets we’ve reviewed so far and is about the same price as the LS31.

Astro A20 Wireless

The LucidSound LS31 is a better gaming headset than the Astro A20. It has lower latency, is more comfortable, and has more control options thanks to the channel mixing dials. It also has a better microphone for online gaming, and its battery life lasts a bit longer than the Astros. On the other hand, the A20 have better sound quality and also have an app to EQ the headphones to your liking. Unfortunately, they can’t be used wired like the LS31 can, and their latency and wireless range are a bit worse.

Turtle Beach Elite Atlas

If you really want a wireless headset for gaming, then the LucidSound LS31 is a better option than the Turtle Beach Elite Atlas. The LS31 provides you with more freedom to move around or to game from your couch without a wire. It also has dials to mix game and chat audio, which is convenient. However, if wireless technology is not a must, the Atlas is more comfortable, better-built, and has great audio reproduction.

6.1 Mixed Usage

Average for mixed usage. While the LucidSound LS31 have decent audio reproduction and are quite comfortable, the bulky design won’t be ideal for commuting or sports. It also doesn’t isolate noise well. Also, the over-ear design isn’t very breathable, and the cups feel loose on the head, meaning they’ll be a mediocre option for sports. On the upside, their low latency dongle allows you to watch TV from your couch without lag or lipsync issues. These headphones also have a great microphone performance for online gaming.

6.7 Neutral Listening

Decent for neutral listening. The LS31 have a powerful and relatively deep bass, a good mid-range, but an underemphasized treble. Unfortunately, their bass is quite boomy and lacks a bit rumble, while the vocals and leads are going to sound thick and cluttered. The treble range is uneven and will lack detail, but will also sound sharp on certain S and T sounds for some. On the upside, you can switch between 3 EQ presets: default, bass-boost or treble-boost.

5.6 Commute/Travel

Sub-par for commuting. The loose fit doesn’t isolate any lower-frequency noises and will let in all the rumble of engines. Also, over-ears gaming headsets aren't easily portable, and it will be hard to travel around with.

5.7 Sports/Fitness

Mediocre for sports. The LucidSound LS31 are bulky, and the over-ear design traps heat inside the ear cups, which will make you sweat more than usual. It also doesn’t hold well on the head, so it will surely sway off your head during physical activity. You’ll also have to use it wired, which means you have a risk of getting the cable caught on something and yanking the headset off.

6.1 Office

Average for the office. While they are comfortable and their battery life will last you long enough for a whole workday, they don't isolate ambient chatter well and is quite leaky, so you won’t be able to raise your volume higher without people surrounding you hearing your music.

7.2 Wireless Gaming

Good for gaming. This headset has a great microphone for online gaming with friends. You can also use the cups’ dials to control the game and chat audio volumes. The USB dongle reduces the latency to a minimal, and you’ll be able to wear the headset comfortably during long gaming sessions. This gaming headset is also very versatile since you can get audio wirelessly on consoles and PCs.
