• TOPAUX USB C Headphones — biggest strength: a full wired audio kit in one box — dynamic-driver stereo sound, in-line controls, three sizes of silicone tips, a cable fixer clip and a zippered PU storage case.
• TOPAUX USB C Headphones — biggest trade-off: it is wired, not waterproof, and the brand itself notes the color can look slightly darker in person than on screen.
• YHNNHJUJ Bass Fishing Bum — biggest strength: one adjustable bag that converts between fanny pack, belt bag, shoulder bag, chest bag and crossbody, with a dedicated headphone jack and room for a 500ml bottle.
• YHNNHJUJ Bass Fishing Bum — biggest trade-off: the polyester is listed as not water resistant, and there is only one pocket, so organization depends on how you pack it.
• Who each pick is for: TOPAUX for anyone who wants better sound and call controls from a USB-C phone, tablet or laptop; YHNNHJUJ for anyone who wants their hands free and their essentials (and music) on their body while moving.
The TOPAUX pair is a wired USB-C earphone built around a dynamic driver with a 20–20000 Hz frequency range and 32 ohm impedance, matched to a DAC chip the brand says delivers lossless stereo sound. In practice, that spec sheet describes a straightforward, low-fuss listen: plug into a Type-C port and go. There is no battery to charge and no pairing dance, which is exactly why wired earbuds still make sense for lectures, long calls, video editing and gaming sessions where you don't want a five-hour battery clock running in the back of your mind.
What makes it more than a bare cable is the accessory set. You get small, medium and large silicone tips, so the fit can be tuned from kids to adults — the brand even suggests the smallest tips for smaller ears. There's a cable fixer clip to pin the cord to your clothes so it stops swinging while you walk, and a nylon braided, tangle-resistant cord with an oxygen copper-free core and a bend-resistant connector. A purple zippered PU case holds the whole thing. The in-line remote handles play, pause, answer, end and reject calls, skip tracks, volume, and even wakes Siri or the Android voice assistant.
YHNNHJUJ Bass Fishing Bum: Who It's For
The YHNNHJUJ bag is a single-piece waist pack made from polyester, sized 13.7" long by 5.5" wide by 5.5" high, with a 30-inch strap and a buckle-plus-zipper closure. It's listed at one size, so the fit comes from the adjustable strap rather than sizing up or down. The headline feature is the dedicated headphone jack: you route your cable through the bag, keep your phone zipped inside, and still listen while you run. That is a small design detail that solves a real annoyance for anyone who has ever juggled a phone and a leash at the same time.
Capacity is the second selling point. The brand lists space for a passport, phone, keys, wallet, tissues and a 500ml water bottle. That's a genuinely useful loadout for a day hike or a festival, and it's the reason the bag works as a crossbody or chest bag too — the strap and shape let it sit across your torso when you want the weight off your hips. It's also machine washable, which matters for something that lives against your body through sweat and dust.
Two honest caveats. First, despite the brand's description calling the material water-resistant in one place, the product information field says not water resistant — so I'd treat it as splash-tolerant at best and keep electronics in a dry pouch on wet days. Second, there's only one pocket, so the "secure zip" promise is about keeping things in, not about separating them. Who should buy it: runners, hikers, dog walkers, travelers and festival-goers who want hands-free carry with music access. Who should skip it: anyone who needs a waterproof pack, multiple compartments, or a structured technical bag for heavy loads.
Side-by-Side: Which Should You Choose?
• Best for audio quality and call control → TOPAUX USB C Headphones. Dynamic driver, DAC chip, in-line volume and mic controls.
• Best for hands-free carrying → YHNNHJUJ Bass Fishing Bum. Adjustable strap, buckle and zip closure, fits a 500ml bottle plus daily essentials.
• Best for music while you move → YHNNHJUJ Bass Fishing Bum, thanks to the built-in headphone jack — though you'd still need earbuds like the TOPAUX to actually hear anything.
• Best for travel and day trips → YHNNHJUJ Bass Fishing Bum. Passport, phone, wallet and water in one place, wearable as a crossbody or chest bag.
• Best for multi-user households → TOPAUX USB C Headphones. Three tip sizes fit kids through adults, and it ships with a storage case.
• Best for wet-weather or swim use → neither. TOPAUX is not waterproof and the bag is listed as not water resistant.
• Best value for the job → depends entirely on the job. They solve different problems, so buying both is a logical combo rather than a duplicate purchase.
If I had to pick one, I'd buy the TOPAUX USB C Headphones. In my opinion, it's the more self-contained product: sound, mic, controls, tips, cable clip and case all arrive in one box, and it works the moment you plug it in. That said, the YHNNHJUJ bag is the smarter buy if your real problem is carrying stuff while staying hands-free — and if you already own wired USB-C earbuds, the bag becomes the more useful upgrade. Check the current price on Amazon before you commit, since both are inexpensive categories where a small difference changes the math.
Yes — they're a Type-C wired earphone, which matches USB-C iPhones (15 and later family), iPads, Samsung Galaxy S/Flip/A models, Pixel and most modern Android phones. If your device still uses Lightning or a 3.5mm jack without an adapter, they won't fit.
Yes. The bag has a dedicated headphone jack so you can keep your phone zipped inside and still run a cable to your ears. You'll need your own wired earbuds to use it.
No. The brand's description mentions water resistance, but the product information lists the water resistance level as not water resistant. Treat it as a dry-conditions bag and protect your electronics separately.
They'll stay in if you fit the right tip size and use the included cable fixer clip, but they are not waterproof and the brand warns against moisture and sweat exposure. For heavy training in the rain, that's a real limitation to weigh.
