If you want translation features and an open-ear fit for computer use, choose JUNJIEUNVO Q39; if you need long battery life and serious noise reduction for loud work environments, choose Tangxi Neckband. Both carry an IPX5 waterproof rating, but they solve completely different problems for a buyer hunting for IPX5 waterproof headphones. One is a translation-forward open-ear pair for desk work and light sport; the other is a neckband built for industrial noise and all-day wear under a collar. Here's how I'd decide between them for computer use.
• JUNJIEUNVO Q39 — biggest strength: open-ear design with translation support across more than 130 languages, plus Bluetooth 5.4 and a charging case. Biggest trade-off: roughly 8 hours of playback per charge and no active noise control.
• Tangxi Neckband — biggest strength: around 20 hours of playtime from a 200mAh battery and 29dB noise reduction aimed at machinery and power tools. Biggest trade-off: in-ear fit and no translation features, so it's a work-and-sport tool rather than a smart desk companion.
• Pick JUNJIEUNVO Q39 if you want open-ear comfort for video calls and wireless headphones for computer use, with translation as a bonus.
• Pick Tangxi Neckband if you work around loud equipment, need concealable earbuds under a collar, and want the longest runtime between charges.
The Q39 leans into being a smart, flexible everyday pair. The open-ear shape means nothing plugs your ear canal, which matters if you spend hours on calls and want to stay aware of what's happening around you. That's exactly the profile of someone searching for comfortable bluetooth headphones for computer — you can take back-to-back meetings without the pressure build-up that closed earbuds create. Bluetooth 5.4 with EDR and a 10-meter range keeps the connection current, and the 32-ohm dynamic drivers cover a standard 20Hz–20,000Hz range.
The headline feature is translation support spanning more than 130 languages. If you work across languages, take international calls, or travel, that capability is the reason to look here rather than at a plain neckband. The 500mAh charging case tops up the 40mAh earbuds, and a full charge takes about 1.5 hours. The IPX5 rating covers sweat and splashes, so a run or a rainy walk won't end the session.
Where it gives ground: about 8 hours of playback at 80% volume is fine for a workday but not a marathon, and there's no noise cancellation at all. If your environment is genuinely loud, this is the wrong tool. In my opinion, the Q39 is for the desk-and-street user who values open ears and translation over raw runtime — and who should skip it if blocking out machinery noise is the priority.
The Tangxi Neckband is unapologetically a work headphone. Its 29dB noise reduction is explicitly aimed at cutting the noise from machinery and power tools, which puts it in a different category from the Q39. If you're landscaping, welding, woodworking, farming, or doing yard work, that reduction figure is the whole point. The neckband design with a low-profile shape can sit under a collar or protective clothing with only the earbuds showing, and the three-layer silicone earplugs are built for all-day wear.
Battery life is the other headline: a 200mAh cell delivering over 20 hours, with a fast top-up of 10 minutes for 2 hours of use. Bluetooth 5.3 handles pairing to iOS and Android devices with a 10-meter range. The IPX5 rating resists damp, splashes, sweat, and light rain, so it holds up across fitness, running, and outdoor jobs.
The trade-offs are real, though. It's in-ear with an ABS build and no translation features, so it's not a smart desk companion. There's also no active noise cancellation in the music sense — the 29dB figure is about blocking environmental noise. In my opinion, the Tangxi is for the tradesperson, fitness user, or anyone whose day is loud and long, and who should skip it if they want open-ear awareness or translation.
Side-by-Side: Which Should You Choose?
• Best for fast top-ups → Tangxi Neckband. A 10-minute charge yields 2 hours of use; the Q39 needs about 1.5 hours for a full charge.
• Best for computer calls and open-ear comfort → JUNJIEUNVO Q39. The open-ear shape suits long sessions at a desk.
• Best for translation → JUNJIEUNVO Q39. Support for more than 130 languages is unique to it here.
• Best for loud job sites → Tangxi Neckband. 29dB noise reduction targets machinery and power tools.
• Best for concealment at work → Tangxi Neckband. The low-profile neckband hides under a collar.
• Best for a modern Bluetooth spec → JUNJIEUNVO Q39. Bluetooth 5.4 with EDR edges out 5.3.
• Best for splash and sweat protection on both → tie. Both carry an IPX5 rating.
If I had to buy one, I'd take the JUNJIEUNVO Q39 for computer use. The open-ear fit, Bluetooth 5.4, charging case, and translation support make it the more versatile companion for calls and desk work, and the IPX5 rating covers sweat and splashes. The Tangxi Neckband wins clearly on runtime and noise reduction, so I'd only switch to it if my day involved loud machinery or I needed to go a full shift-plus without charging. For most people reading this, the Q39 is the smarter all-rounder.
are headphones waterproof
Not usually. In this comparison, both the JUNJIEUNVO Q39 and the Tangxi Neckband are rated IPX5, which means they resist splashes, sweat, and light rain — not full submersion. So treat IPX5 as water-resistant for everyday conditions, not swim-proof.
are headphones water resistant
Yes, when they carry an IPX rating like IPX5. Both products here are IPX5, so they handle damp, sweat, and light rain. That's enough for workouts, yard work, and commuting, but neither is designed to be dunked or worn in the pool.
It has 29dB noise reduction aimed at blocking machinery and power tool noise, which is a work-environment feature rather than music-style active noise cancellation. If you need to mute a loud job site, that's the strength here.
In my opinion, the JUNJIEUNVO Q39. Its open-ear design keeps you aware during long sessions, and Bluetooth 5.4 with EDR supports a stable connection to a computer. The Tangxi Neckband is better suited to loud environments than to desk-based calling.
