AI Verdict
These 7.7-ounce on-ear headphones offer 50 hours of battery life and Spatial Audio, but lack active noise cancellation.
These headphones are a strong fit if your main priorities are exceptional battery life (up to 50 hours), dual-platform compatibility, and a lightweight design (7.7 ounces) for moderate listening sessions. However, the absence of active noise cancellation and reported comfort issues for extended wear make them less ideal for consistently noisy environments or all-day use.
If you need active noise cancellation or superior comfort for long listening periods, look for over-ear headphones with dedicated ANC technology and larger earcups that fully enclose the ear.

Pros
- Up to 50 hours of battery life means you'll charge them infrequently, with one user reporting 84 hours and 18 minutes in testing.
- Fast Fuel provides 5 hours of playback from a 10-minute charge, useful for quick top-ups.
- Supports Personalized Spatial Audio with dynamic head tracking for Apple users.
- Works with both Apple (one-touch pairing, iCloud sync, Find My) and Android (Google Fast Pair, Find My Device, Beats app) devices without compromise.
- Includes both USB-C and 3.5mm audio cables, allowing wired listening even when the battery is dead, and supports lossless audio via USB-C.
- AI-powered voice isolation on the microphone makes calls clearer by cutting through background noise.
Cons
- No Active Noise Cancellation (ANC) means significant struggle with blocking low-end environmental noise like traffic or plane engines.
- Comfort can be an issue for extended listening sessions, with pressure building on the ears and skull for some users after 1.5 to 2 hours.
- The Android app offers minimal functionality, primarily for battery life and basic controls, lacking an equalizer or audio customization.
- Sound quality is described as more neutral than older Beats models, but some users find it thin, treble-y, or flat, especially compared to over-ear alternatives.
- No IP rating for water resistance means they are not certified for sweat or rain, limiting their use for intense workouts.
Dimension Scores
The updated drivers and custom acoustic architecture deliver a balanced sound with punchy lows and clear audio for popular music, but some users find it lacks depth or has overemphasized highs.
These headphones only offer sound isolation and completely lack Active Noise Cancellation, struggling significantly with blocking low-frequency environmental noise.
The 7.7-ounce ultralight design and UltraPlush ear cushions provide comfort for short periods, but many users report discomfort and pressure after 1.5 to 2 hours of continuous wear, especially for larger heads.
With an advertised 50 hours of playback and some tests showing even longer durations (up to 84 hours), the battery life is among the best in its category.
Best For
- Commuters who prioritize long battery life and don't need active noise cancellation for moderately noisy environments.
- Users who switch between Apple and Android devices frequently and need seamless pairing on both platforms.
- Individuals seeking a lightweight (7.7 ounces) and foldable on-ear design for portability.
- Listeners who appreciate a punchy, balanced sound profile for popular music genres and podcasts.
Not Recommended For
- Frequent flyers or daily commuters in very loud environments who require active noise cancellation.
- Users with larger heads or those who wear headphones for multi-hour sessions, due to reported comfort issues and clamping force.
- Audiophiles who demand extensive audio customization via an app or a completely flat, analytical sound signature.
Watch Out For
- The lack of Active Noise Cancellation (ANC) is a significant omission at this price point, making them less effective in loud environments like public transport.
- Some users report discomfort and pressure on the ears after about 1.5 to 2 hours of wear, especially for those with larger heads.
- The sound profile, while more balanced than previous Beats, is still described as having overemphasized highs and underemphasized bass and mids by some reviewers, resulting in a 3.9/10 overall MDAQS score in one test.
- The earcups do not swivel, which can make them less comfortable when resting around your neck.
- There's no IP rating, so while they are lightweight for workouts, they aren't certified for sweat or water resistance, potentially impacting longevity.

What Buyers Say
The most surprising finding is the wildly varied reports on battery life, with some users hitting the advertised 50 hours and others pushing past 80 hours in testing, which is truly exceptional for wireless headphones. Many users are happy with the sound for casual listening and the seamless pairing across both Apple and Android devices. However, the consistent complaint about the lack of Active Noise Cancellation at this price point is a major drawback, as is the discomfort that sets in for many after a couple of hours of wear.
“Honestly, I was hyped for these but no ANC at this price is just ridiculous, and my ears start aching after an hour and a half. Battery life is insane though, like seriously, I barely charge them. But the comfort, man, it's a dealbreaker for my big head.”
Common Praise
- The 50-hour battery life is a game-changer, with some users reporting days of use without needing a charge.
- Fast Fuel charging is incredibly convenient, giving 5 hours of listening from just 10 minutes of charging.
- Seamless pairing and functionality with both Apple (Spatial Audio) and Android (Fast Pair) ecosystems is a big plus.
- The sound is described as powerful, with clear audio and a noticeable bass presence for popular music.
- The lightweight (7.7 ounces) and foldable design makes them easy to carry around.
- The inclusion of both USB-C and 3.5mm cables for wired listening, even when the battery is dead, is appreciated.
Common Complaints
- No Active Noise Cancellation is a huge miss, especially for the price, making them less useful in loud environments.
- Comfort issues arise after 1.5 to 2 hours of wear, with tightness and pressure on the ears and head being common complaints.
- The sound quality, while improved, is not universally loved, with some finding it thin, treble-y, or lacking the 'Beats bass' of old.
- The Android app is very basic, offering no EQ or significant customization options.
- The earcups don't swivel, which can make them awkward to rest around your neck when not in use.
- No IP rating for water resistance means they aren't ideal for sweaty workouts despite their light weight.
Ownership Tips
- The 'ultralight' feel (7.7 ounces) is noticeable, making them easy to forget you're wearing for short bursts, but the clamping force becomes apparent over time.
- The physical buttons are tactile and easy to locate without looking, which is a nice change from touch controls on some other headphones.
- The included soft carrying case is functional but requires you to 'shove' the headphones in, which doesn't feel very protective.
- The AI-powered mic really does make a difference for calls, even in moderately noisy places, but wind is still a challenge.
- You'll likely find yourself using the wired connection more than you expect, especially for devices without Bluetooth or when you want to preserve battery.
Frequently Asked Questions
Do the Beats Solo 4 have Active Noise Cancellation (ANC)?
No, the Beats Solo 4 do not feature Active Noise Cancellation. They rely on sound isolation, which helps with some ambient noise but struggles with low-frequency sounds like engine hums.
How long does the battery last on a single charge?
The Beats Solo 4 are rated for up to 50 hours of battery life. Some users have reported getting around 40-45 hours, while one test even achieved 84 hours and 18 minutes.
Are these headphones comfortable for long periods?
Comfort is mixed; they are ultralight (7.7 ounces) with UltraPlush ear cushions, making them comfortable for short listening sessions. However, some users experience pressure and fatigue after 1.5 to 2 hours, especially if they have larger heads.
Can I use these with both Apple and Android devices?
Yes, the Beats Solo 4 are designed for seamless compatibility with both Apple and Android. Apple users get one-touch pairing and Spatial Audio, while Android users benefit from Google Fast Pair and the Beats app.
Do they support wired listening?
Yes, they come with both a 3.5mm audio cable and a USB-C cable. You can listen wired via either connection, even if the battery is completely depleted, and USB-C supports lossless audio.
What is the sound quality like?
The sound is described as powerful and balanced, with updated drivers and a more neutral profile than older Beats models. Some users find the bass punchy and vocals clear, while others perceive it as thin or overly bright.
Buying Guide
When looking at on-ear headphones like these, you need to think about how long you'll actually wear them and where. On-ear designs sit directly on your ears, which can be lighter and more portable, but often lead to discomfort faster than over-ear models that cup your whole ear. Battery life is crucial for wireless headphones – a higher number means less charging hassle. Also, consider if you need active noise cancellation; if you're often in loud places, passive sound isolation won't cut it.
On-Ear Type
Unlike over-ear headphones that fully enclose your ears, on-ear headphones rest directly on them. This usually means a more compact design and lighter weight (7.7 ounces here), but it can also lead to pressure and discomfort on your ears after a couple of hours, like wearing a tight headband for too long.
50-Hour Battery Life
This number tells you how long the headphones will play music on a single charge. 50 hours is a lot – imagine going on a week-long trip and only needing to charge them once, or even less frequently for daily commutes.
Sound Isolation (No ANC)
Sound isolation means the physical design of the earcups blocks some external noise. It's like putting your hands over your ears. Active Noise Cancellation (ANC) uses microphones and electronics to actively cancel out noise, especially low-frequency hums. Without ANC, these headphones won't silence a rumbling bus or airplane engine, they'll just muffle it a bit.
Alternatives
If you need true silence for travel or office work, look for over-ear headphones with active noise cancellation. If comfort for all-day wear is paramount, prioritize over-ear designs with larger, plush earcups and a lighter clamping force.
