Finding decent budget earbuds is tricky. Finding ones that don’t feel like cheap plastic toys is even harder.
Sony essentially owns the premium earbud space with their flagship XM series. But not everyone wants to drop $300 on headphones they might leave on the subway. That’s exactly why the Sony WF-C500 existed. It was the safe, reliable, under-$100 option.
Then Sony dropped the WF-C700N. They shrank the design, crammed in Active Noise Cancellation (ANC), added multipoint Bluetooth, and asked for slightly more money.
So, do you save a few bucks and grab the older WF-C500, or step up to the C700N?
I’ve spent weeks shuffling both pairs between my gym bag, my desk, and my pockets. I wore them on windy outdoor runs, noisy coffee shop sessions, and boring Zoom calls. One is definitely a better daily driver. But the older model actually beats the new one in a couple of frustratingly obvious ways.
Here is exactly how they compare in the real world.

Is the Sony WF-C500 Good?
The WF-C500 feels like the Honda Civic of true wireless earbuds. Nothing flashy. No leather textures or aluminum accents. Just a solid piece of tech that works every time you pull it out of the case.
They rely entirely on passive isolation meaning they physically block noise like earplugs because there’s no ANC chip inside. And honestly, they do a decent job of it.
The most surprising thing about them is the battery. Ten hours on a single charge is massive. I’ve literally worked a full 8-hour shift wearing these, left them on my desk, and used them the next morning without tossing them in the case.
But they show their age. The charging case lid feels uncomfortably thin. It has this frosted, translucent plastic that looks neat but feels like it might crack if I sit on it wrong.
What I Like
- Massive 10-hour single-charge battery life.
- Detailed, punchy sound (especially with the Sony app EQ).
- Physical buttons are huge and easy to hit on a run.
- Surprisingly light in the ear despite the bulky look.
- Extremely affordable these days.
- IPX4 rating handled my sweaty gym sessions fine.
What Could Be Better
- The translucent case lid feels cheap and brittle.
- Zero ANC or ambient sound modes.
- Pushing the buttons forcibly pushes the earbud deeper into your ear.
- No multipoint connection (cannot connect to phone and laptop at once).
Pros & Cons
| Pros | Cons |
| Incredible standby and single-use battery | Case lid lacks durability |
| Clean, customizable sound profile | Missing modern ANC features |
| Reliable physical buttons | Pushing buttons causes ear pressure |
| Great value for money | Bulky casing |
Personal Recommendation
If your budget is incredibly tight and you care strictly about battery life and sound quality, these are still highly relevant. They are perfect as a “beater” pair of gym earbuds you won’t cry over losing.
Final Rating: 7.5 / 10
Is the Sony WF-C700N Good?
Sony clearly listened to the complaints about the C500. The WF-C700N fixes almost every physical issue the previous generation had.
First off, they are tiny. Sony claims they are 37% lighter and 38% smaller than their predecessor. You feel that immediately. They disappear into your ears. I have weirdly shaped ears that usually reject larger buds after an hour, but the C700N stayed comfortable through an entire afternoon of podcasts.
Adding ANC at this price bracket is a huge win. It’s not mind-blowing silence, but it takes the aggressive edge off traffic noise and airplane hum. Plus, they finally added a transparency mode, meaning I don’t have to yank an earbud out every time a barista talks to me.
But the battery situation is annoying. Because the buds and the case are so much smaller, the battery capacity tanked. You get one extra charge from the case. Just one. That means you’ll be plugging this case into the wall a lot more often.
What I Like
- Super comfortable, low-profile fit. Excellent for smaller ears.
- Decent ANC blocks out the low rumble of daily commuting.
- Ambient mode sounds surprisingly natural, not robotic.
- The textured, opaque charging case feels much more durable.
- Multipoint Bluetooth works flawlessly (after a firmware update).
- Mesh microphone covering actually helps with wind noise.
What Could Be Better
- 15-hour total battery life is disappointingly low for this year.
- Still using SBC and AAC codecs (no LDAC for high-res audio).
- The ANC struggles with high-pitched noises (like sirens or crying babies).
Pros & Cons
| Pros | Cons |
| Excellent ergonomics and lightweight fit | Weak total battery life with case |
| Solid ANC and ambient sound | High-pitched noise still bleeds through |
| Multipoint Bluetooth support | Only one extra charge in the case |
| Sturdier, textured charging case | No high-res LDAC support |
Personal Recommendation
This is the one most people should buy. The combination of comfort, ANC, and multipoint Bluetooth makes them a vastly better companion for working from home or daily commuting.
Final Rating: 8.8 / 10
Detailed Head-to-Head Comparison
Let’s break down exactly how these two compare across the things that actually matter during daily use.
Sound Quality
Both earbuds punch way above their price class. Sony refuses to make bad-sounding audio gear.
The WF-C500 uses a 5.8mm driver, while the newer WF-C700N uses a slightly smaller 5mm driver. You would think the older model sounds better, but they are incredibly close. Both support Sony’s DSEE technology, which tries to upscale compressed Spotify or Apple Music tracks.
Out of the box, the C700N sounds slightly warmer. It has a bit more mid-bass presence that makes pop and hip-hop feel energetic. The C500 is a bit flatter and more analytical.
The real magic for both happens in the Sony Headphones Connect app. Sony’s custom EQ is arguably the best in the business. The “Clear Bass” slider lets you crank up the thump without muddying up the vocals. I spent about five minutes tweaking the EQ on both, and honestly, blindfolded, it’s hard to tell them apart on sound alone.
✅ My Take: Tie. Both sound fantastic for the price once you tweak the EQ.
- WF-C500 Rating: 8/10
- WF-C700N Rating: 8.5/10
Comfort and Fit Stability
This is a slaughter. The C700N destroys the older model here.
The WF-C500 is bulbous. It sticks out of your ear slightly. If you try to lie down on a pillow with them, they press painfully into your ear canal. While running, I occasionally felt the C500 slowly wiggling loose due to the sheer weight of the outer shell.
The C700N is tiny, sleek, and incredibly ergonomic. Sony used a lot of the design data they gathered from their premium LinkBuds S to shape the C700N. They sit flush against the ear. I took them on a heavy 5-mile run, sweating profusely, and I barely had to adjust them once. If you have smaller ears, do not even consider the C500. Just get the C700N.
✅ My Take: WF-C700N wins easily. It’s vastly more comfortable for long sessions.
- WF-C500 Rating: 6/10
- WF-C700N Rating: 9.5/10
Battery Life
This is where things get weird. The older, cheaper earbud actually destroys the newer one.
The WF-C500 gives you 10 solid hours of playback on a single charge. The case holds another 10 hours. That’s 20 total.
The WF-C700N maxes out at 7.5 hours with ANC on. That’s perfectly fine for a workday. But the case only holds one single extra charge, bringing the total to a measly 15 hours.
I found myself dealing with battery anxiety with the C700N. I’d grab the case on a Monday, and by Tuesday afternoon, the case was completely dead, forcing me to hunt for a USB-C cable. With the C500, I could throw them in my bag and forget about charging them for over a week.
✅ My Take: WF-C500 takes the crown. The tiny case on the C700N severely limits its backup juice.
- WF-C500 Rating: 9/10
- WF-C700N Rating: 6.5/10
ANC / Passive Isolation
Well, only one of these actually has Active Noise Cancellation.
The C500 relies completely on the physical silicone ear tip sealing your ear canal (passive isolation). It blocks out high frequencies decently well. Keyboard clacking, people talking nearby—it muffles them. But the low rumble of a bus engine? It cuts straight through.
The C700N uses real ANC. For a sub-$100 earbud, the ANC is surprisingly competent. It erases low-frequency hums easily. The AC unit next to my desk completely vanished. Traffic noise outside my window became a whisper. It won’t match a $300 Bose earbud, but it does exactly what you need it to do on a noisy commute.
Plus, the Ambient Sound mode on the C700N is great. A quick button press and the microphones pipe in the outside world so you can hear announcements at the train station. The C500 forces you to yank the bud out of your ear to hear anything.
✅ My Take: WF-C700N wins by default, but the implementation is genuinely good.
- WF-C500 Rating: 5/10 (Passive only)
- WF-C700N Rating: 8/10
Call Quality and Controls
Both earbuds use tactile push buttons rather than touch-sensitive panels. I strongly prefer this. With sweaty fingers at the gym, touch panels always fail. Physical buttons just work.
However, because the C500 is bulkier, pushing the button feels like you are shoving the earbud into your brain. The C700N is smaller and sits better in the ear, making the button press much more comfortable.
For phone calls, the C700N has a distinct edge. Sony added a wind-noise reduction mesh structure around the microphone on the new model. I took a call walking down a windy street in Chicago. The person on the other end said I sounded a bit robotic on the C700N, but they could actually understand me. On the C500, the wind noise completely blew out the microphone.
✅ My Take: The WF-C700N is much better for outdoor phone calls.
- WF-C500 Rating: 6/10
- WF-C700N Rating: 8/10
Case Design and Durability
I hate the WF-C500 charging case. The translucent pill shape looks like a cheap breath mint container. The lid hinge feels flimsy. I dropped it on a hardwood floor once and the lid popped completely open, scattering the earbuds across the room.
The C700N case fixes this. It’s slightly smaller, made of an opaque, heavily textured plastic. It feels sturdy. The texture also hides fingerprints and pocket scratches perfectly. The magnets holding the earbuds in the case feel stronger too.
Both earbuds are rated IPX4, meaning they can survive sweat and light rain, but you can’t drop them in a pool.
✅ My Take: The C700N case feels like a real tech product. The C500 case feels like a toy.
- WF-C500 Rating: 5/10
- WF-C700N Rating: 8.5/10
App Support and Extra Features
Both use the exact same Sony Headphones Connect app. It’s one of the best companion apps on the market. You get full EQ control, battery readouts, and firmware updates.
But the C700N unlocks a massive feature: Multipoint Bluetooth.
You can connect the C700N to your phone and your laptop at the exact same time. If I’m watching a YouTube video on my Mac and my iPhone rings, the earbuds automatically switch over so I can answer the call. When I hang up, the audio switches back to the Mac.
The C500 requires you to manually disconnect from one device before connecting to another. If you switch between devices a lot, multipoint is not just a luxury; it’s a necessity.
✅ My Take: Multipoint connection makes the C700N the undisputed winner here.

FAQs
Can you run with the Sony WF-C700N and WF-C500?
Yes. Both carry an IPX4 water resistance rating, which easily protects them against heavy sweat and light rain. However, the WF-C700N is significantly smaller and lighter, making it much more stable in your ear during high-impact activities like running or jumping rope.
Do the Sony WF-C500 and WF-C700N support multipoint Bluetooth?
Only the WF-C700N supports multipoint Bluetooth, allowing you to connect to two devices (like a phone and a laptop) simultaneously. The older WF-C500 does not have this feature. Note: If you buy the C700N, you may need to update the firmware via the Sony app out of the box to enable multipoint.
Is the ANC on the Sony WF-C700N actually good?
For the price, yes. It effectively cancels out low-frequency, constant noises like airplane engines, bus rumbles, and air conditioners. It will not block out high-pitched noises or sharp voices as effectively as premium $300 models, but it makes a massive difference for daily commuting.
Are the Sony WF-C700N good for small ears?
Absolutely. The C700N was specifically designed to be smaller and lighter than previous generations. They sit flush in the ear and do not protrude outward, making them one of the best budget options on the market for people with small ears.
Does the Sony WF-C500 case break easily?
The translucent lid on the WF-C500 case is known to feel slightly brittle. While it won’t shatter from normal daily pocket use, it definitely lacks the premium, durable feel of the thicker, textured case found on the WF-C700N. Drops onto hard surfaces can cause the C500 lid to pop open.
