The Beats Solo 4 Wireless are the next generation of the Beats Solo3 2019 Wireless. While Beats is more so known for its premium products, these cans sit as a lower-end option for those who prefer an on-ear fit. They maintain all their predecessor's sleek, colorful design elements but with some small improvements, like a built-in digital-analog converter (DAC), USB-C audio support, and Android quick-pairing. However, if you've been waiting for a successor to the Beats Solo Pro Wireless, you may be disappointed, especially since this fourth-gen model doesn't support active noise cancelling (ANC).
The Beats Solo 4 Wireless are very good for neutral sound. These on-ears differ greatly from Beats's bass-heavy reputation over the years. They're fairly neutral, with a balanced bass range to provide adequate thump, punch, and boom. Vocals and instruments sound clear in mixes, while the extra treble makes them sparkle. Unfortunately, this added top-end also makes mixes a bit fatiguing to listen to. Even though they only support basic Bluetooth codecs, you can use them via analog or wired USB to stream high-quality audio.
The Beats Solo 4 Wireless are fair for commute and travel. They're a little bulky but lightweight and can fold into a more compact shape, allowing you to store them in their carrying case. They're also decently comfortable and last over 48 hours continuously, which will be more than enough for long days on the go. Unfortunately, they don't have noise cancelling, and as a result, they struggle to block out background noise like the rumble of plane engines.
The Beats Solo 4 Wireless are decent for sports and fitness. They're lightweight, stable on-ear, and have a decently comfortable fit. Using them wirelessly also helps reduce the chances of something snagging the headphones off your head. Plus, they come in a couple of different colorways, so you can stand out at the gym. Unfortunately, they don't have an IP rating for water resistance, but that's not uncommon for on-ear headphones.
The Beats Solo 4 Wireless are okay for office use. These flashy cans have a decently comfortable fit and have a long enough battery life to get you through your week without needing a recharge. That said, they have a few caveats: they don't have ANC and struggle to passively block out background noise like talkative coworkers. They don't support multi-device pairing either, so you can only stay connected to your PC or smartphone, not both.
The Beats Solo 4 Wireless are Bluetooth-only headphones. Their latency is too high to be used for this purpose unless you like lipsync mismatch.
The Beats Solo 4 Wireless are decent for wired gaming. Using them with their analog cable will only give you audio support, but you can passthrough audio and mic signals with their USB cable. Their neutral sound is well-suited for dialogue-centric gameplay like party banter or instrumentals like sweeping cinematic cutscenes. That said, they lack the utility of customization features found on dedicated gaming headsets. Their integrated mic also offers a disappointing overall performance.
The Beats Solo 4 Wireless are sub-par for phone calls. They have an integrated mic, but it does a disappointing job as a whole. Your voice lacks depth while also sounding muffled. If you're taking a call in a noisy environment like a busy office, background sounds can also compete for attention over your voice. These on-ears also lack noise cancelling, so you'll hear a lot of what's happening around you—that's not ideal if you're easily distracted.
The Beats Solo 4 Wireless come in a few different colorways: 'Matte Black,' 'Slate Blue,' and 'Cloud Pink.' We tested the Slate Blue colorway; you can see our model's label here. If you come across another variant of these headphones, let us know in the forums, and we'll update our review.
The Beats Solo 4 Wireless are the 2024 successor of the Beats Solo3 2019 Wireless, and while nearly five years have passed since the last update, the most significant change is in their sound. They're a lot more neutral sounding, which fans of Beats' previous bassy offerings may find a tad disappointing, but it's a win for those looking for something more balanced. Like the Beats Studio Pro Wireless, they also have a built-in DAC and support USB-C audio, so you can listen to high-quality, lossless audio. One Touch Pairing and Quick Pair replace the H1 chip as well, so it's still simple to connect the headphones to your iOS or Android device. Unfortunately, if you were hoping to upgrade from your noise cancelling Beats Solo Pro Wireless, you may want to hold off since the Solo 4 don't have an ANC system.
Check out our picks for the best on-ear headphones, the best headphones for running, and the best wireless Bluetooth headphones.
The Beats Solo Pro Wireless and Beats Solo 4 Wireless have different strengths, and depending on your preferences, you may like one of the other. The Solo Pro have the edge over the newer Solo 4 if you're looking for noise cancelling. Only the Solo Pro have an ANC system, and they do a significantly better job of reducing ambient sound around you. They also have an H1 chip for seamless pairing with iOS devices, though the Solo 4 support their own quick pair feature with both iOS and Android. That said, the Solo 4 support Spatial Audio and can be used via analog or USB in addition to Bluetooth. Their battery life is longer, too.
The JBL Live 670NC Wireless offer more customization and extra features than the Beats Solo 4 Wireless. While both on-ears are similarly comfortable and well-built, the JBL have companion app support, including a parametric EQ and presets, and they have ANC. While it does a mediocre job of blocking out background noise, it's still better than the Beats' passive capabilities. They also support multi-device pairing and have a significantly longer continuous playback time. However, the Beats have a more neutral sound profile, which some users may prefer, and can also be used via wired USB.
The Beats Studio Pro Wireless are the over-ear counterpart of the Beats Solo 4 Wireless, which are on-ear headphones. Both have a similar sound, but only the Studio Pro have a couple of EQ presets when using their built-in DAC via USB. The Studio Pro also have noise cancelling and can block out a good amount of ambient sound so that you can focus on your audio. However, the Solo 4 are cheaper and offer similar levels of comfort and build quality.
The Beats Solo 4 Wireless are the next generation of the Beats Solo3 2019 Wireless with a couple of updates in performance. While both on-ears look pretty similar (colorways aside), the fourth-gen have a much more neutral sound profile with a tapped-down bass that's less boomy and muddy than their predecessor. They also deliver more treble, which makes vocals and instruments bright to the point where they can be fatiguing to hear over long listening sessions. Although they don't have a W1 chip, they support quick pairing with iOS and Android devices. They have a longer continuous battery life, too. They even support Apple's Spatial Audio feature for a more immersive sound experience.
Beats put a lot of emphasis into design language, and it shows throughout their products. The Beats Solo 4 Wireless' colorful rounded frame feels playful, while their monochromatic colorways help them stand out against the sea of black and beige competitors. The manufacturer's logo is embossed on both ear cups, while the hinges are made of brushed steel to give it a more refined look. They're available in three different colorways, including 'Slate Blue' and 'Cloud Pink' as well as 'Matte Black' for those who want to keep the flashiness to a minimum.
These on-ears have a decently comfortable fit. Their ear cups don't clamp quite as tightly as their predecessor, so they don't feel as fatiguing when worn for long listening sessions. The silicone headband is pretty grippy and can tug at your hair if you're playing with the fit. There are also a few parts of the headphone that can catch errant hair—the hinges, as well as the space behind the yoke, can pull out long flowing tresses if you're not careful.
These headphones have okay controls. They're mostly found on the left cup and are integrated into the Beats logo. The center 'b' button handles your basic playback commands, while the outer circle is a volume rocker. The right ear cup also has a power/Bluetooth pairing button. For a full list of commands, you'll want to check out the user manual here. It's worth noting that Apple's own user manual for these headphones states that the power button is on the left cup. It's on the right cup.
Overall, the controls are easy to locate and use. The buttons are also clicky. There are chimes for turning the headphones on and off, but that's about it.
These headphones are somewhat portable. Thanks to their hinges, they can fold inwards to help conserve space. They're still bulky, and if you put them in their carrying case, they'll take up room in your bag or purse.
They come with a good carrying case made from a durable woven fabric, which feels thick and tough. There's a zipper to help keep the headphones safe inside. Inside the case is a soft lining material. There isn't any internal compartment to keep the cables separate from the headphones, though. You can see how these cans fit into their case here.
The Beats Solo 4 Wireless have a good build quality. They're mostly made of plastic but with brushed metal accents, particularly on the hinges, which make a satisfying clicking sound when you're adjusting the fit. There's also silicone padding on the bottom of the headband to keep the headphones in place, as well as a silicone rubber jacket to cover the cable. The ear cups also have a supple faux leather padding, but it's a little stiff. The previous model's hinges were prone to damage over time and could fail. We don't know if this model will experience those same issues, but it's something to know when manipulating these headphones.
The Beats Solo 4 Wireless deviate from the classic bassy sound seen in past iterations. Instead, they're much more neutral sounding and are closer in response to the Beats Solo Pro Wireless. They have extra treble to make vocals and instruments sound bright and detailed, making them a solid choice for listening to content like podcasts or folk music. All this treble can be harsh and fatiguing over long listening sessions. If you crave the boomy, rumbly sound from predecessors like the Beats Solo3 2019 Wireless, you may be disappointed. But, if you're willing to give them a chance, they still deliver a pleasing bass for most kinds of audio content. Unfortunately, there are no sound customization features available.
Although we tested their sound using Bluetooth, you can check out this graph to see how they perform with different connections. There isn't a difference in frequency response when it comes to analog vs Bluetooth vs USB. It's worth mentioning that the headphones have a built-in DAC that lets you play lossless audio from your phone or computer via USB-C, though. If you're taking a call, the headphones will sound different, though. You'll lose out on bass and treble, making your audio sound more hollow and dull.
These headphones' frequency response consistency is excellent. On-ear headphones can be a little finicky if you want a consistent sound since they're sensitive to how they're placed on your ears. That said, the overall deviation is still fairly low, so as long as you take the time to ensure a good fit, you'll receive more consistent sound.
These headphones have outstanding bass accuracy. Unlike older Beats products, they have a flat and neutral response in this range. As a result, they can reproduce satisfying thump, rumbly, and boom, but not to the extent that it drowns out or muddies vocals and instruments.
Their mid accuracy is great. The response in this range is tilted towards the treble, so vocals and instruments like guitars and pianos are full-bodied but are a bit boxy-sounding. In songs like Obsessed by Olivia Rodrigo, her voice in the chorus is pushed forwards, sounding harsh as well as a bit honky.
The Beats Solo 4 Wireless have decent treble accuracy. The response is overemphasized in this range, so vocals and instruments are bright to the point that they're harsh. Sibilants like cymbals are also piercing. Overall, all this extra treble can be fatiguing to hear, especially if you're listening to audio for long periods.
These headphones' peak-and-dip performance is great. Across the bass to mid range, the headphones can control their sound profile quite well, with a couple of small deviations. A dip in the low-mid thins out vocals and instruments a bit, while a peak in the high-mid brings out their clarity. Another peak in the low treble further emphasizes the detail in vocals and instruments before dipping in higher registers, dulling these sounds. A big spike in the mid-treble makes sibilants like hi-hats piercing.
The imaging performance of these headphones is outstanding. While we've tested a few Beats products with imaging issues, the Beats Solo 4 Wireless are a solid indication of the manufacturer's quality control and ergonomics. It's worth mentioning that imaging varies between units, though. Our unit's L/R drivers are well-matched in group delay, which ensures tight bass and transparent imaging. Additionally, the headphones are well-matched regarding amplitude, frequency, and phase response, so sound objects like voices and instruments are accurately placed in the soundstage.
The passive soundstage performance of these on-ears is poor, but that's to be expected from on-ear headphones. Unlike over-ears, they have reduced interaction with your outer ear, which needs activation by sound to give you a more out-of-head soundstage. Instead, sound feels like it's coming from inside your head, and the soundstage itself seems narrow. Since they're closed-back headphones, they also have trouble creating an open and spacious sound.
If you're an iOS user, you can access Apple's Spatial Audio. You can turn on/off head tracking via the volume Control Center, which allows audio to follow your head movements. If you're an Android user, you can use Dolby Atmos, though you'll need audio formats that support this feature.
The weighted harmonic distortion performance is very good. There are a couple of peaks at moderate volumes, including in the bass and treble ranges. While it can affect the purity of your audio, distortion is difficult to hear unless you're an astute audiophile.
These are the settings used to test these headphones, and our results are only valid when used in this configuration.
These headphones have a poor noise isolation performance, but that's to be expected from passive on-ears. Unlike the Beats Solo Pro Wireless, they lack noise cancelling and aren't designed to block out sound. As a result, you'll hear much of the low rumble of traffic to colleagues at the office chatting to the high-pitched hum of computer fans.
While there's a bump above zero in the bass range in our Noise Isolation - Full Range graph, this is produced only when used on our test rig. You won't experience this in your day-to-day use.
Like with Full Range noise isolation, the Beats Solo 4 Wireless won't block out much of common scenarios like traffic on a busy street or the ambient sounds of an office either.
There's also a bump above zero in the bass range in this Noise Isolation graph, which appears only when used on our test rig. You won't experience this in your day-to-day use.
The Beats Solo 4 Wireless have a decent leakage performance. Most of their leakage is concentrated in the treble range, which sounds thin. That said, if you like to jam out to your tunes at high volumes, others around you will hear it.
These on-ears have multiple beamforming mics, but our rig can't test them to their fullest potential. That said, these mics have poor recording quality. Your voice really lacks depth and body. At the same time, speech is a bit muffled and distorted, making it harder to follow your voice. You can only use the mic via either Bluetooth or wired USB, as analog doesn't support mic pass through.
The integrated beamforming mics' noise handling performance is sub-par. Our rig can't test these mics to their fullest extent. However, in our test, these mics had a hard time separating speech from background noise. If you're taking a call in a busy street or office, the sound around you is also loud and present in the call, but it doesn't completely overpower your voice.
The Beats Solo 4 Wireless' battery performance is excellent. The manufacturer advertises 50 hours of continuous playtime with the volume at 50%, and we measured a similar amount. They also have a Fast Fuel feature, where charging the headphones for 10 minutes gives you up to five hours of playback. Luckily, if you're short on battery life and need your headphones ASAP, you can use them while charging or even use them passively with their analog cable.
If you have an iOS device, you'll get a built-in pop-up that displays basic information like your battery level, firmware, and app version, as well as links to more general information. You can also access Find My Beats if you lose your headphones, and there's a single control you can remap: you can change the mute/unmute and end call control from one press to double press, which isn't much. You can't disable them either or have both set to the same command.
If you're an Android user, you'll have to download the Beats app, but you'll get all these same features.
These headphones include a 1/8" TRS cable and a USB-C to USB-C cable. Both can be used for audio, though using the USB cable will result in a little more latency than analog. It isn't very noticeable unless you're working on something delay-sensitive.
The Beats Solo 4 Wireless have great Bluetooth connectivity. Although they lack an H1/W1 chip found in the Beats Solo Pro Wireless and thus don't support multi-device pairing within the Apple ecosystem, they have quick pairing support for both Android and iOS devices. They can also use the Audio Sharing feature on the iOS platform, allowing two compatible devices to stream audio from the same Apple device.
They're sparse on codec support. You'll have access to the two codecs: SBC and AAC. SBC has somewhat high latency, so if you're using it, you'll notice that your audio and visuals are out of sync. If you're looking for high audio quality, you'll want to consider using the headphones via their USB-C connection instead of Bluetooth.
These headphones can be connected to your PC wirelessly via Bluetooth with full audio and mic support. If you want to use them via analog, you'll only hear audio (and can't use the mic), so if you're looking for a full-rounded performance, use the USB-C cable instead.
You can plug the Beats Solo 4 Wireless into your PlayStation controller's AUX port for audio support. However, you can only use the USB cable for full compatibility on the PS5. The volume is very quiet, and you need to connect the cable to the console, not the controller, which makes this method very unwieldy.
