Does the Galaxy S21 Have a Headphone Jack?
Short answer: no, the Samsung Galaxy S21 does not have a headphone jack. Samsung dropped the 3.5mm port on this generation, betting hard on wireless audio and a slimmer build. If you’re still loyal to a favorite pair of wired headphones, you’ll need a USB-C to 3.5mm adapter—and ideally one with a built-in DAC (digital-to-analog converter) if you actually care about sound quality. It’s the same playbook Apple ran a few years earlier, and honestly, it’s not going away. Below I’ll walk through why Samsung made this call, how to get wired audio working anyway, and what’s changed since the S10 days.
Key Takeaways
- No, the Galaxy S21 doesn’t have a 3.5mm headphone jack—Samsung cut it starting with the S20 line.
- Wired headphone fans need a USB-C to 3.5mm adapter, and a DAC-equipped one is worth the extra few dollars.
- Bluetooth audio works great here; the S21 handles wireless earbuds and headphones without any hiccups.
- Older flagships like the Galaxy S9 and S10 still had the jack—the S20 was the actual turning point.
- This isn’t Samsung being difficult; it’s chasing the same slim-body, wireless-first trend the rest of the industry is on.
Why Samsung Ditched the Headphone Jack on the Galaxy S21

Losing the 3.5mm jack is probably the most-debated design choice on the Galaxy S21, and I get it—it’s the port a lot of us grew up with. But from an engineering standpoint, cutting it lets Samsung shave down bezels and keep the phone thin without shrinking the screen. This isn’t a first for the brand; the trend actually started with the Galaxy S20, and Samsung is simply following where Apple already went with the iPhone 7. Consumers, whether they love it or not, have been steadily buying into wireless audio anyway, which makes the decision easier to justify from a sales perspective. There’s also the accessory angle: no jack means more reason to buy Galaxy Buds or a Bluetooth headset, which obviously helps Samsung’s bottom line. Love it or hate it, the S21 is firmly built around a minimalist, cable-free vision of how you listen to music.
How to Use Wired Headphones on a Galaxy S21 (No Jack Required)
Good news: plugging in wired headphones is still possible, it just takes one extra piece of hardware. You’ll need a 3.5mm-to-USB-C adapter, and I’d strongly recommend one with a built-in DAC rather than a bargain-bin cable—that chip is doing the actual work of converting the digital signal into something your headphones can play, and skipping it usually means flatter, thinner-sounding audio. Samsung sells its own adapter, but plenty of third-party options do the job for less; just double-check the listing mentions a DAC and confirms USB-C compatibility with the S21 before you buy. Setup itself takes seconds: plug the adapter into the phone’s USB-C port, then plug your headphones into the adapter. From there, how good it sounds really comes down to the quality of both the adapter and the headphones themselves—a $10 adapter paired with $200 headphones is going to bottleneck things. Still, these dongles are small enough to toss in a bag, so wired listening on the S21 is inconvenient but far from impossible.
Galaxy S21 vs. Older Samsung Phones: When Did the Jack Disappear?
If you’re upgrading from an older Samsung phone, this is where the confusion usually comes from. The Galaxy S9 and S10 both had a standard 3.5mm jack, so you could plug in any pair of wired headphones without a second thought. That changed with the Galaxy S20, and the S21 simply continues that direction rather than reversing it. In other words, this wasn’t a one-off decision for the S21—it’s now Samsung’s standard across two full generations of flagship phones. The trade-off is exactly what you’d expect: slimmer hardware and more internal room for battery or camera components, at the cost of plug-and-play wired audio. If you’re coming from an S10 or earlier, budget for that adapter, because you’ll need it.
Wireless Alternatives and Accessories That Actually Work Well With the S21
With the jack gone, most S21 owners end up going wireless, and honestly the experience holds up well. Samsung’s own Galaxy Buds run on Bluetooth 5.0, which gives you solid range and a stable connection even walking room to room. A lot of these earbuds also support aptX Adaptive, a codec that keeps audio quality high without needing a cable at all. If you’d rather stick with wired gear, the USB-C to 3.5mm adapters mentioned earlier let you keep using your existing headphones, and many now double as chargers so you’re not choosing between listening to music and topping up your battery. Pricing across both adapters and wireless earbuds tends to land somewhere between $10 and $30 for budget picks, which keeps this accessible even if you don’t want to spend flagship-earbud money. Worth noting too: a good chunk of today’s wireless earbuds include active noise cancellation, which makes a real difference on a noisy commute or in a busy office.
What Losing the Headphone Jack Actually Means for You
Stepping back, dropping the 3.5mm jack changes more than just how you plug in headphones—it touches design, cost, and even how Samsung makes money off you after the sale. On the upside, that slimmer, jack-free body genuinely feels better in hand and looks more premium sitting on a table. On the downside, you’re now stuck either buying wireless gear or carrying an adapter, and either way that’s an extra cost and one more thing you can forget at home. There’s a business angle here too: Samsung clearly benefits from pushing customers toward its own Galaxy Buds and accessory lineup, and fewer physical ports also mean less material and packaging, which Samsung likes to frame as a sustainability win. Whether you buy that argument or see it as a convenient excuse, the bigger picture is clear—phone makers have decided wireless is the future, and jack-equipped phones are becoming the exception rather than the rule. If you’re shopping for new earbuds anyway, look at models with Bluetooth 5.2 connectivity, since the newer standard delivers noticeably better range and battery efficiency than older Bluetooth versions.
