Treblab X11 Wireless Bluetooth Earbuds 01

I’m a firm believer in futurism, the coming-true of farfetched science fiction concepts. One of the seemingly impossible devices I remember reading about was featured in Ray Bradbury’s dystopian novel Fahrenheit 451. The main character’s wife would lie awake at night listening to the “beetles” in her ear — tiny radio earbuds — chittering away deep into the night.

I used to long for such devices to exist, truly wireless earbuds, so that I could listen to my own music unhindered by cables or heavy batteries. And wouldn’t you know that less than 20 years after reading that book, I’d be holding in my hands something very similar to a then-preposterous concept, the Treblab X11 Bluetooth Earbuds.

Comes with everything shown, including two complete sets of earplugs, both foam and rubber. Very welcome!

In 2017, Treblab’s “truly wireless earbuds,” as they call them, are actually not such an usual device. All the same, I was amazed at how small and lightweight the X11’s were and eager to put them to the test.

What’s in the box?

The Specs

The X11 earbuds sport Bluetooth 4.1 profile, a 6-hour battery life, 38-foot signal range (which seemed accurate in my testing), and an inline mic for placing and receiving phone calls. Charging was a simple affair thanks to the special split micro-USB cable that allowed for both earbuds to be charged simultaneously.

The included charging cable is split at the end to charge both earbuds from the same cord.

Interestingly, powering on just one earbud activates both the left and right audio channels for single-earbud use. I believe that’s what gave me such a hard time with the pairing process. It’s a bit of a chore to get both earbuds paired to the device and each other, as they show up as two separate devices in the Bluetooth pairing process. But after the initial weirdness, everything was pretty smooth.

Durability and Design

The construction of the earbuds seemed very solid. I’d say that they’re fine to toss into a front pocket or gym bag, but I’d probably stick them in their case or a smaller container simply to avoid losing them. After placing them in my ears, they were practically weightless. There’s virtually no chance they would accidentally fall out of your ears.

You’d be very hard-pressed not to find a perfect fit for your ear canals with at least one of the six supplied eartips. There are 3 sizes of both foam and rubber tips, which felt generous to be given so many options.

Both earbuds have a button on them that acts as play/pause for music and answer/hang-up for phone calls. There is no volume control on them. The buttons are located directly over your ear canals, so the force required to press them forced the earbuds painfully deeper.

One quirky feature of the earbuds is that while they’re powered on, they flash a very bright blue light. About every 8 seconds or so. The entire time they’re on. Since I was testing these at work, I chose to cover up the buttons with tape to keep from distracting my neighbors (and myself) with the blue strobes. But I imagine that steady blinking would be great for visibility in low-light running.

Pay no mind to the tape I placed over the flashing, blue lights.


Initially, I found the sound quality a bit lacking. The bass seemed weak and the treble a little too hissy. But then I realized that the default eartips were a bit too loose for my ear canals. Once I switched over to a larger set and formed a better seal, the sound quality improved dramatically.

After finding the right fit and EQ setting, the sound quality jumped up to very good. The bass was punchy, mids seemed very clean and the treble, while still a little too hissy for my taste, did not deteriorate and contrasted clearly with the heavy bass. I’d consider them to be perfect for workouts and running. The volume reached dangerously loud levels at around 50% of my iPhone’s volume threshold, so it’s safe to say they’re plenty loud. Hours into the testing, I was genuinely surprised they sounded as good as they did, considering their tiny size, wireless connectivity and relatively unheard-of brand.

But then, brand isn’t everything.

I managed to get about 5 hours of battery life out of them before I got a spoken “low battery” voice prompt in my left ear. The battery level dropped from 30% to 20% in a moment and then powered off very soon after that. They won’t carry you through a full work day, but a long run or gym session? No problem.

If you’re in the market for a pair of wireless earbuds that you can throw in your ears and essentially ignore after that, at just under $80, Treblab’s are tough to beat.

  2. I agree with everything you said about these earbuds! They’re comfortable (and I’m hard to please) and last plenty long enough for my use. I found them to be a quality buy at a reasonable price.

    1. Thanks for the feedback, Pam, they’re certainly a good alternative for those interested in Apple’s AirPods. They might lack a little of the fancy bits like charging case and W1 chip, but they’re about half the price and won’t make you wait 6 weeks to arrive!

  3. I love the Trelab X11 but after about a year of use every day the wing part broke. Contacted Trelab and they said they do not sell the spare part, but give me a 20% discount off buying new ear buds on their website unfortunately they do not sell them on their website. Do any of you know of a replacement wing that would fit my X11

    1. Ahh, that’s a bummer. From the looks of these wings and how they attach, they look pretty custom fitted for these earbuds in particular. I can’t imagine there are any generic options out there. I guess the only thing you could possibly do is check out some other cheap earphones in the store and see if those have little wings that look like they could fit. Or 3D print a spare based off one that you do have, but that’s such a crazy stretch, heh. Sorry I couldn’t help!
