You’re standing in a crowded terminal, trying to catch a flight, and your boss calls. Or maybe you're just trying to shout over a leaf blower while walking the dog. If you've just dropped a couple hundred bucks on the new Beats Solo 4, the first thing you probably wondered—after "do these fit my head?"—is whether people on the other end can actually hear you.
Do Beats Solo 4 have a mic? Yeah, they definitely do. But it's not just some tiny hole drilled into the plastic as an afterthought.
Honestly, the microphone situation on these on-ears is one of the biggest upgrades over the old Solo 3, yet it's the part people talk about the least. We get so caught up in the "50-hour battery life" or the "no ANC" drama that we forget these are primarily communication tools for most of us. Let's get into what’s actually happening inside those ear cups.
The Tech Inside the Ear Cups
Beats didn't just stick with the status quo here. They swapped the old analog mics for something called Digital MEMS (Micro-Electro-Mechanical Systems) microphones. Why should you care? Because analog mics are prone to picking up electronic "hiss" and interference. These new digital ones are much cleaner.
But the real magic is the digital beam-forming.
Basically, the headphones use multiple microphones to create a sort of "audio flashlight." They aim that beam right at your mouth while trying to ignore the person arguing about their latte behind you. According to Apple's technical specs, they even ran these through over 7,000 hours of "real-world noise" training. They basically taught an algorithm what a jackhammer sounds like versus what you sound like.
Where is the mic located?
You won't see a boom arm sticking out like a gaming headset. The mics are integrated into the housing of the ear cups. If you look closely at the bottom edges of the ear cups, you’ll see tiny, precision-drilled ports. These allow the MEMS sensors to pick up external sound for the "noise learning" algorithm while the primary beam-forming mics focus on your voice.

How it Actually Sounds in the Real World
Look, no Bluetooth headphone mic is going to sound like a $500 Shure SM7B in a padded studio. It’s just physics. But for a pair of on-ears, the Beats Solo 4 performs surprisingly well.
In a quiet room? You sound crisp. Maybe a little "compressed," which is typical for Bluetooth’s limited bandwidth, but very clear.
In a windy park? That’s where things get interesting. The "advanced voice-learning algorithm" does a decent job of clipping out the low-frequency rumble of wind. It won't make the wind disappear entirely—nothing does—but it ensures your voice doesn't get drowned out. Tech reviewers from outlets like CNET and SoundGuys have noted that while the sound can feel a bit thin compared to the over-ear Beats Studio Pro, the clarity is a massive jump from the Solo 3.
The Wired Mic Mystery (Read This Before You Buy a Cable)
Here is something that trips people up constantly. The Beats Solo 4 supports three ways to listen:
- Bluetooth (Wireless)
- USB-C (Wired / Lossless)
- 3.5mm Analog (Wired)
If you are using them wirelessly, the internal digital mics work perfectly. If you plug them in via the USB-C cable, the internal mics still work. This is great for office workers who want a stable connection for Zoom calls while charging at the same time.
However, if you use the 3.5mm analog cable, things change. The cable included in the box is a standard "TRS" cable. It doesn't have an inline microphone. And because the 3.5mm jack on the headphones is a passive connection (it works even when the battery is dead), it doesn't always "talk" to the internal digital mics depending on your device. If you're a gamer wanting to use these with a PS5 or Xbox controller via the 3.5mm jack, you might find that the mic doesn't work unless you buy a specific "RemoteTalk" cable with a built-in mic.
Beats Solo 4 vs. The Competition
If mic quality is your #1 priority, you have to look at the landscape.
- Beats Studio Pro: These have more internal mics and a larger housing, which generally leads to a slightly fuller vocal tone.
- Sony WH-1000XM5: These are the "gold standard" for mic isolation, but they also cost significantly more and aren't as portable.
- AirPods Max: Better mics, but they’re heavy enough to give you a neck workout.
The Solo 4 sits in this weird middle ground. It's for the person who wants something light (only 217 grams!) that they can throw in a bag, but still needs to take a 20-minute sync-up call without the other person saying "What? Can you repeat that?" every five seconds.
Is It Good for a Call Center?
I saw a thread on Reddit recently where someone asked if they should use these for a professional call center job.
Short answer: No.
Long answer: For casual office work or "work from home" life, they’re great. But for 8 hours of back-to-back professional calls, you want a dedicated headset with a physical boom mic. The Solo 4 is an on-ear design. That means it sits on your ears, not around them. After three hours, that clamping force can start to feel like a slow-motion head-crush. Plus, without Active Noise Cancelling (ANC), you’ll hear everything your coworkers are saying, which is distracting.
Actionable Insights for Solo 4 Owners
If you already own these or are about to pull the trigger, here is how to get the best mic performance:

- Update the Firmware: If you're on Android, download the Beats app immediately. Apple users get updates automatically. These updates often tweak the "noise learning" algorithms.
- Use USB-C for Calls: If you're at a desk, use the USB-C cable. It bypasses Bluetooth compression and ensures you never run out of juice mid-sentence.
- Check Your "B" Button: Remember that the "b" button on the left ear cup is your command center. A single press mutes or unmutes your mic during a call—super handy if the dog starts barking.
- Placement Matters: Ensure the ear cups are sitting squarely on your ears. Because the mics are beam-forming, if the headphones are tilted too far back on your head, the "beam" might miss your mouth slightly, making you sound distant.
The Beats Solo 4 isn't a revolutionary piece of tech, but the microphone system is a legitimate, "grown-up" improvement. It takes the Solo series from being "just for bass-heads" to something that actually works for a modern, mobile lifestyle. Just don't expect it to cancel out a crying baby in the seat next to you—that’s a job for the Studio Pros.
