Quick Answer: No, the Galaxy S21 does not have a headphone jack. To use wired headphones with the Galaxy S21, you’ll need a 3.5mm AUX adapter.

While there aren’t many major Samsung Galaxy S21 changes compared to the S20, a few key updates make the S21 a more affordable option.

Like the iPhone 12, this iteration of Samsung’s flagship smartphone doesn’t come with a charger. This is an effort to reduce electronic waste and help keep the phone’s price down.

Samsung has been known for years for its high quality and sleek design. The Galaxy S21 line is no different.

This may lead some potential buyers to wonder what other things might be left out. The Galaxy S20 line from Samsung released in 2020 was the first Galaxy phone to launch without a headphone jack.

This came several years after Apple began producing iPhones without the 3.5mm headphone port. But what about the Galaxy S21?

Does the Galaxy S21 have a headphone jack?

Short answer: No

Samsung has decided to leave the headphone jack off the Galaxy S21. All Galaxy S21s, including the S21 Plus and S21 Ultra, don’t have a headphone jack.

So what does this mean for Samsung smartphone users? While there is no headphone jack on the Galaxy S21, you still have other options.

Firstly, there are a plethora of Bluetooth headphone options available. The Galaxy S21 supports any Bluetooth headphones. Another option is using a USB-C to 3.5mm adapter to connect wired headphones to the Galaxy S21.

Using a USB-C to 3.5mm adapter with headphones simultaneously prevents your phone from charging.

Where is the headphone jack on the Samsung Galaxy S21

Sadly, the Galaxy’s S21 headphone jack is gone, but with all the wireless options available, it seems logical to start phasing them out.

Instead, the Galaxy S21 phones rely on USB-C or wireless Bluetooth connectivity for audio output. This was likely done to save space for other components and align with industry trends of removing the 3.5mm port.

Users who still prefer wired headphones can utilize a USB-C to 3.5mm headphone adapter to connect legacy headphones. But otherwise, wireless or USB-C audio accessories are required for private listening with the Galaxy S21.

Nowadays, phones are thinner and more ergonomic. Plus, not having a phone jack also cuts down a little on prices, which is good for everybody.

    So, where do you plug in the 3.5mm adapter? Into the charging port? I’m confused.

    The adapter gets plugged into the USB-C jack, where you would plug it in to charge. Hope this helps!
