Ttbesmi JM18

The Ttbesmi JM18 is a $25 open-ear bud with surprisingly good build quality and comfort, especially for small ear canals. Battery life is the big weakness at just 4 hours per charge, and the voice prompts are stuck in Japanese. If you want open-ear comfort on a budget for workouts, it's a solid pick. If you need all-day battery or ANC, skip it.

Let's talk about what these actually do well. The build quality is the standout here. At the 91st percentile, these things feel more solid than they have any right to at $25. The ear-hook design is lightweight and the weight distribution is good. Owners with small ear canals, a group that usually gets left out of the earbud conversation entirely, are consistently praising these for being comfortable where everything else hurts. That's not nothing.

Sound quality sits at the 70th percentile, which is about average for the category but honestly impressive for the price. The AAC codec helps on the audio side, and the open-ear design means you're not getting deep, thumping bass. That's the trade-off. You get situational awareness and comfort, but you give up the sealed, immersive sound of in-ear buds. The mic quality at the 82nd percentile is a pleasant surprise. Two mics with noise reduction means calls are clearer than you'd expect from a budget open-ear set. Connectivity is solid at the 73rd percentile, and Bluetooth 5.4 gives you a stable connection with decent range.

The JM18 sits in an awkward spot. Against the Soundcore P31i, you're giving up battery life and sound quality but gaining the open-ear comfort that in-ear buds can't match. The P31i is a better all-around product, but it's also a different category. If you want sealed sound and ANC, the JM18 isn't your pick. The EarFun Air Pro 4+ is another strong competitor with better specs across the board, but again, it's an in-ear design.

The Anker Space A40 is a different beast entirely. It's a premium in-ear bud with excellent ANC and battery life, but it costs significantly more. The JLab JBuds Pods ANC is closer in price and offers ANC, but the comfort story is completely different. If you have small ear canals or just hate the pressure of in-ear buds, none of these competitors solve that problem the way the JM18 does. The Beats Powerbeats Fit is the closest in concept with its ear-hook design, but it's in a completely different price bracket.

At $25, the JM18 is priced to move. You're getting Bluetooth 5.4, an IPX5 water resistance rating, a charging case with a digital battery display, and a build quality that punches way above its weight class. The value proposition is strong if you're looking for open-ear buds for workouts and don't need all-day battery life.

Compared to the competition, this is a budget play. The Soundcore P31i and EarFun Air Pro 4+ are both more expensive and offer better battery life and sound quality, but they're also in-ear designs. If you specifically want open-ear, the JM18 is one of the cheapest options that doesn't feel like it'll fall apart in a week. The trade-off is that 4-hour battery and the language quirk. For a gym session or a run, that's fine. For a long flight or a full workday, it's not.

The Ttbesmi JM18 is one of those products that makes you do a double take. It's a $25 pair of open-ear, bone conduction style earbuds with an ear-hook design, Bluetooth 5.4, and a charging case with a little LED battery readout. On paper, that's a lot of features for the price of a pizza and a soda. In practice, it's a mixed bag with some genuinely surprising strengths and one very specific, very annoying quirk.

Who is this for? Runners, cyclists, gym rats, and anyone who hates the feeling of silicone tips jammed into their ear canals. The open-ear design means you hear your music and the car honking at you, which is kind of the whole point. Our data shows the build quality sits in the 91st percentile for this category, which is wild for a budget product. The mic quality is also strong at the 82nd percentile. Comfort lands at a solid 73rd percentile, and that tracks with what owners are saying.

But here's the thing. The battery life is rough. Four hours on the buds and 20 hours total with the case puts it in the 13th percentile for battery. That's near the bottom of the barrel. For a sports-focused product, that's a real limitation. And then there's the language issue. More on that in a bit, because it's the kind of thing that either makes you laugh or makes you return the product.

If you need all-day battery life, the JM18 is not your friend. Four hours per charge is fine for a workout or a commute, but it's not going to get you through a workday or a long flight. The 13th percentile battery ranking is a real limitation, and the charging case only gets you to 20 hours total. If you're a heavy user, look at the Soundcore P31i or EarFun Air Pro 4+ instead.

Also skip these if you want immersive, bass-heavy sound. The open-ear design is great for awareness but terrible for thumping low end. If you listen to bass-heavy music or want to block out the gym noise, get a pair of in-ear buds with ANC. The Anker Space A40 or JLab JBuds Pods ANC will serve you better. And if the Japanese voice prompts would drive you crazy, that's a legitimate reason to pass. It's a small thing, but it's the kind of small thing that grates on you every single time you power them on.

If you have small ear canals or find in-ear buds painful, the JM18 is worth a serious look. The comfort story is real, and at $25, it's a low-risk experiment. The build quality is genuinely impressive, and the mic quality will surprise you on calls. Just know that you're signing up for 4-hour battery life and a voice prompt system that speaks Japanese with no easy fix.

For runners and cyclists who want situational awareness without spending Beats money, this is a solid budget pick. For anyone who needs all-day battery life, strong bass, or ANC, look elsewhere. The JM18 is a specialist, not a generalist. It does one thing really well: comfortable, open-ear listening at a price that's hard to argue with.
