JBL Tune 310C review: these feature-rich wired earbuds pack plenty of features, but could sound a little neater

JBL Tune 310C review

The JBL Tune 310C are a budget pair of wired earbuds designed to bring “hi-res” audio directly to you, for less than $25 / £15 / AU$30. At this price, you’re unlikely to be expecting a whole lot – and you’re not wrong; buds this cheap can often falter with tinny audio, a flat design and limited feature-set. But this isn’t the case here.

I’ll be upfront: you’re not going to get stunning sound quality out of the JBL Tune 310C. Sure, they can decode hi-res-quality files thanks to their built-in digital to analogue converter (DAC), but I rarely felt that I was getting a massively detailed listen. Despite that, I wouldn’t say the JBL Tune 310C are an unpleasant-sounding pair of in-ears.

When tuning into Black Eye by Allie X, bass displayed solidity, but the swift kick of the drum machine sounded a touch lethargic, meaning the track didn’t quite have its distinctive “bounce” – something the best wired earbuds are able to replicate. Meanwhile, vocals were clear, neither muffled nor distorted, although when switching to I Want You by Moloko, the singer’s breathiness was fairly muted, resulting in a less detailed, natural-sounding listen.

However, given their price, I’d still argue that the JBL Tune 310C offer adequate audio. The resonant bass and clean vocals alone make for a decent all-round listen, even if subtle intricacies are missing. Treble is pretty bright, too, when listening to Electric Tooth Brush by Toronto; I was struck by the snappy high-pitched percussion. While such delivery might wear you down after some time, it’s suited to songs with a more excitable sound signature. And even with that brightness, I’d argue that these buds rarely become grating, inflicting tinny audio onto your ears, such as the Belkin SoundForm Wired Earbuds with USB-C connector, for example.

Note that if you’re not loving the sound of the JBL Tune 310C, you’re able to tweak it to your liking. That’s because these buds come with three built-in EQ options – something that isn’t an option even in high-calibre, pricier alternatives such as the Master & Dynamic ME05. The EQ preset options included are Default, which offers a more balanced sound; Bass, for ramped up low-end power; and Vocal, for focusing on voices in podcasts, news broadcasts, or similar.

And they do all sound unique, which is a big plus point in my view. Having said that, I did mostly find myself sticking with Default. Don’t get me wrong, I’m a lover of bass-heavy bangers, but the Bass mode can occasionally sound a little bloated in the low-end. For instance, the drum machine in Black Eye hit with more depth in this mode, but in turn, also sounded less agile and a touch muddy.

Meanwhile, Vocal mode works very nicely when watching dialogue-heavy content, whether that’s a documentary on one of the best streaming services or a podcast on Spotify. It isn’t the best for listening to music, however, since it sometimes casts a tinny layer over your favorite tracks; I’d use it sparingly.

One feature that improves the overall user experience is the inclusion of multiple sizes of ear gels, ensuring a comfortable listen regardless of your ear shape. Unlike the loose-fitting JBL Tune 305C, this enables you to form a proper in-ear seal, opening you up to the world of passive noise isolation. Is this super effective? Not really. I could still hear the odd nugget of speech when listening at around 50% volume. Nevertheless, it did dull excess noise – the sound of colleagues typing, for example. And far more effectively than the Tune 305C can.

One final feature worth mentioning is the JBL Tune 310C’s built-in mic and controller. The controller allows you to adjust volume, toggle play/pause, take calls or adjust EQ (by holding the volume up and down buttons simultaneously). Pretty neat! And the built-in mic is surprisingly good, too. When making a call and taking a voice recording, my speech could sound a little on the quiet side, but my voice was clear and pretty uninterrupted by static – something even the more expensive buds can suffer from.

In terms of looks, these wired earbuds are pretty middle of the road. The flat wire, despite being conveniently tangle-resistant, is pretty prone to bending, which isn’t so pretty to look at. And similarly to the Tune 305C, there’s plastic casing on the outside of the buds that looks a little cheap, in my opinion. I’m a fan of the small-sized USB-C adapter and handy controller, though – neither of which suffered any connectivity issues. The buds also arrive in some neat color options, including black, blue, red and white.

In my view, there are only a couple of hold-ups in terms of design. First, I experienced quite a lot of cable noise when on-the-go. Sure, that’s an inherent issue with many buds that have eartips; but it could become quite distracting when I was moving around. Second, there’s a lack of waterproofing – something I always like to have for added peace of mind if using these buds in the rain, for example.

Otherwise, though, I was pleased with what the Tune 310C could provide. They’re pretty comfortable in-ear and aren’t too hefty, meaning they won’t slip out all too easily. Audio, although unremarkable, is certainly solid given the Tune 310C’s budget cost, especially when you consider the tuning available through their three EQ modes.

So, if you’re looking for some cheap, feature-rich earbuds, then these JBL buds are worth considering. The SoundMagic E80D are better still, if you have a little extra cash – simply for the upgrade in sound quality. Plus the Skullcandy Set USB-C are a decent alternative, if you want some waterproof buds.

JBL Tune 310C review: Price and release date

• $24.95 / £14.99 / AU$29
• Launched in 2024

The JBL Tune 310C released in 2024 around the same time as the JBL Tune 305C. The latter are a looser-fitting variant more akin to the Apple EarPods. They have a very modest list price of $24.95 / £14.99 / AU$29, which is pretty much inline with the 305C and competitors like the Apple EarPods, for instance. That price is typically the same regardless of the color option you pick. For reference, these are available in black, blue, red and white.

JBL Tune 310C review: How I tested

• Tested for one week
• Used in the office and while on walks
• Predominantly tested using Tidal

I put the JBL Tune 310C to the test over the course of one week. When trying out these buds, I predominantly spent my time listening to music, which I did in the main through Tidal on the Samsung Galaxy S24 FE. However, I also tried them out with YouTube and Spotify on my Windows laptop.

When listening, I played through all the tracks in our TechRadar testing playlist, which contains songs from a variety of genres – read our guide on how we test earbuds for more. In addition, I spent hours tuning into songs from my personal library, while also using them in a variety of environments, including busy streets and the office at Future Labs.
