It’s been over a year since Samsung launched the Galaxy Buds 3 and Galaxy Buds 3 Pro. As such, you may be wondering what exactly is going on with Samsung’s next premium wireless earbuds. Rumors have been pointing to a release in early 2026, possibly launching during the first Galaxy Unpacked of the year. Outside of a few other details, there isn’t a whole lot of information to parse through yet. However, we are learning something new today about the next-generation earbuds — the model numbers.
Although stable One UI 8 is just starting to arrive on Galaxy devices, Samsung is already working on One UI 8.5. That update appears to have leaked, as some people are digging into an alleged modified build. In a tip sent to Android Authority, the code within that build seems to provide the very first reference to the Galaxy Buds 4 and Galaxy Buds 4 Pro.

But this leak doesn’t only give us a confirmation on the product names. Additional strings of code may have revealed the model numbers for both pairs of earbuds. According to that code, the Galaxy Buds 4 come with the model number SM-R540. Meanwhile, the Galaxy Buds 4 Pro feature the model number SM-R640.

If you remember, the Galaxy Buds 3 had the model number SM-R530, while the Galaxy Buds 3 Pro’s model number was SM-R630. So the model numbers of the fourth-generation earbuds make a lot of sense.

Sounds Nerdy Insights
- What’s pretty wild about this leak is it shows Samsung moving forward toward major releases really fast. They’re just rolling out One UI 8, and here we already have whispers about 8.5! It makes me think about how companies can't afford to sit back anymore — time really is money in tech.
- It's also fascinating how model numbers play into all of this. They essentially give us clues about progression. Not just product identity but hints at quality assurance too—Buds 3 felt great, so you can bet Samsung wants to keep that momentum with Gen 4.
- We're clearly gonna see an evolution if they stick to tradition. Do they push for better sound quality? Extended battery life? Maybe even some crazy new features? Who knows!
- But it begs the question: are enough people ready to upgrade those earbuds again? Hopefully, they pull off a pricing strategy that's smart ‘cause no one wants to break the bank on new tech anymore—me included!
- And let’s not forget competition: With brands stepping up their game in wireless audio (looking at you AirPods), it’ll be interesting to see what unique features Samsung conjures up to stand out. Seriously, tech developers need to keep innovating. Sticking with the status quo doesn’t cut it!
- On a brighter note, this feeling of anticipation around new products might actually get consumers buzzing! Nothing lights up our fervor like fresh colors or styles coming across our feeds—it energizes the crowd!
- Overall, while we gotta hold notably, onto our excitement for now, these leaks suggest there could be significant growth opportunities in wireless earbuds yet again... and you can bet I'll be tracking this as it unfolds!
