JBL Tune 305C review
If you’re on the hunt for some new earbuds but you’ve not bought into the whole wireless thing, the JBL Tune 305C could be an enticing budget option. These wired earbuds promise punchy bass, a comfortable fit – not a bad package for £16.75 / AU$24 (about $21). So can the JBL Tune 305C live up to these bold promises, or do they instead fall flat?
Well, let’s start where it matters most – sound. Of course, the main attraction is meant to be JBL’s “Pure Bass” sound but despite providing enjoyable warmth, this won’t conjure up the low-end boom that bass heads may want. For instance, when I tuned into Black Eye by Allie X, there was a solid amount of depth to the thumping drum machine, but it lacked the impact and prominence in the mix to really have my head bopping. When listening to All Night Long by Chris Stussy, the bouncing bass never sounded lethargic or unresponsive, but again, it wasn’t as hard-hitting as I’d hoped.
You can be assured, however, that bass won’t sound nasty and distorted. Similarly, I didn’t experience much in terms of tinniness in the treble range or overly thin mids – something that all our picks of the best wired earbuds are capable of circumventing. But clean audio isn’t always a given with budget buds – the Belkin SoundForm Wired Earbuds with USB-C Connector, for instance, are very cheap… and they sound it. The JBL feel like good value in comparison.
Another positive is that the JBL Tune 305C can play hi-res music files thanks to the inclusion of a built-in digital to analog converter (DAC) – pretty impressive for some buds that come in at £16.75 / AU$24 (about $21). But although overall audio is certainly clear, it doesn’t really sound massively detailed.
For instance, I tuned into Clair de Lune by Kamasi Washington and piano notes soaring up and sinking down sounded slightly clumped – where they’d sound more individualized and defined using more premium buds such as the Sennheiser IE 200. Piano was also given a lot more breathing space with the IE 200, whereas it sounded more muddied with the Tune 305C – but not to a degree that it was totally lost in the mix.
One reason that I didn’t get a massively nuanced, informative listen from the Tune 305C was their in-ear fit. Like the Apple EarPods USB-C, they’re pretty loose-fitting, with an ‘open-ear’ design. They don’t include eartips, like the SoundMagic E11D, for example, meaning sound is less concentrated into the ear canal. Some may prefer the looser feel of these – I can’t deny that they were easy to keep in for longer listening sessions.
But still, they would occasionally feel as if they were falling out, especially when I was on the go. Not ideal if you’re on a run or working out. This design choice also limits noise isolation, so you may have to put up with the sound of that wailing baby on your four-hour flight… uh oh.
But again, some may prefer the more relaxed feel of the Tune 305C. On top of that, these are pretty lightweight and didn’t subject me to all too much cable noise – impressive for buds at this price-point.
And that’s not all – you also get a neat controller, which has volume, play/pause and mic controls built-in. Firstly, I have to say I was very impressed with mic quality. There was some very slight tinniness on a phone call, but my voice was nice and clear. Meanwhile, a voice recording came through with limited background static and well-defined vocals – rare for lots of wired earbuds.
You’re not going to believe me, but the fun doesn’t stop there either. If you hold down the volume up button for two seconds, you can even switch between Standard, Bass and Voice modes. EQ settings are pretty rare for cheap wired earbuds, so I was delighted to find this here. Really, the only downside practicality-wise is the lack of waterproofing, which would be ideal for listening in the rain or when exercising.
Another slightly disappointing aspect of these earbuds is their design. The buds each have a raised piece of plastic with the JBL logo on which looks a little clumsy, and the flat wire might not be to everyone’s taste either. Don’t get me wrong, my eyes didn’t burn just looking at the Tune 305C, but I was hardly swooning over them. The controller looks decent, however, and is positioned near your cheek for easy access, not to mention that the wire – despite not being too pretty – is tangle-resistant, which is useful if you need to slide these into your pocket.
All in all, the JBL Tune 305C are a solid pair of in-ear buds. They have typically clean audio with commendable bass and volume, EQ options and a surprisingly good mic. The loose fit does come with sacrifices in the audio and noise isolation departments and it’s a shame not to see waterproofing too. But at £16.75 / AU$24 (about $21), there’s still plenty to like here.
If you want a step-up USB-C option, the SoundMagic E80D will outperform the Tune 305C in most departments, but there are some nice cheaper options too, such as the Skullcandy Set USB-C.
JBL Tune 305C review: Price and release date
- £16.75 / AU$24 (about $21)
- Launched in 2024
The JBL Tune 305C launched in 2024 – the same year that the audio specialists dropped the Tune 310C model, which uses ear tips for a more snug, noise-isolating listening experience.
These in-ears are typically priced at £16.75 / AU$24, making them a very budget-friendly option. They’re also available in a number of attractive color variants including: Black, Blue, Red and White – I tested the latter for this review.

JBL Tune 305C review: How I tested
- Tested for one week
- Used in the office and on public transport
- Predominantly tested using Tidal
I tested the JBL Tune 305C over the course of one week. When I used these buds for music listening, I mainly used Tidal on the Samsung Galaxy S24 FE, but I also tried them out with YouTube and Spotify on my Windows Laptop.
Not only that, but I made sure to run through tracks in the TechRadar testing playlist, which contains songs from a variety of genres – read our guide on how we test earbuds for more. I did, however, also spend hours tuning into songs from my personal library. And I took the 305C with me everywhere for this review. I tested them at a busy London train station, on walks through my local town centre and in the office.
