How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a rugged, drop-proof hard-shell case that keeps a Shokz OpenFit 2+ charging case locked shut and shielded from splashes, choose PROfezzion Shokz OpenFit 2+; if you need a complete set of Bluetooth work headphones with 29dB noise reduction, 20 hours of playtime and IPX5 water resistance for the job site, choose Tangxi Neckband.
• PROfezzion Shokz OpenFit 2+ — biggest strength: a heavy-duty, full-coverage hard shell with a secure locking latch and a non-slip silicone pad, rated IPX5 for splashes and spills.
• PROfezzion Shokz OpenFit 2+ — biggest trade-off: it is not a pair of headphones. It is a protective case built only for the 2025 Shokz OpenFit 2+, and it will not fit the OpenFit Air (2024) or OpenFit 1 (2023).
• Tangxi Neckband — biggest strength: a full neckband Bluetooth headphone system with 29dB noise reduction, Bluetooth 5.3 and over 20 hours of battery life on a 200mAh cell, all IPX5 water resistant.
• Tangxi Neckband — biggest trade-off: it is a work-and-fitness tool first. The 29dB reduction is tuned for machinery and power tools, and the low-profile neckband design favors concealment and stability over a lifestyle look.
• Who each is for: the PROfezzion case is for someone who already owns Shokz OpenFit 2+ headphones and wants to stop the charging case popping open in a bag or on a drop; the Tangxi Neckband is for someone who needs a self-contained headset for landscaping, welding, woodworking or running.
Think of this as armor, not audio. The PROfezzion case is a hard-shell protector made from ABS, polycarbonate, metal, plastic and silicone, and it wraps the OpenFit 2+ charging case in full coverage. The spec sheet lists it as dust resistant, shockproof, spill resistant and lightweight, with an IPX5 water-resistance rating — meaning it shrugs off splashes and spills rather than full submersion. If your OpenFit 2+ charging case lives loose in a backpack, a gym bag or a work truck, that's the scenario this product was designed around.
Buy it if you own the 2025 Shokz OpenFit 2+ and want drop and spill protection with a latch that actually stays closed. Skip it if you have the OpenFit Air or the original OpenFit — the compatibility note is explicit, and this shell is not built for those. Also skip it if you're shopping for headphones; this is an accessory only.
Tangxi Neckband: Who It's For
The Tangxi Neckband is the opposite kind of product: it's the whole listening chain, minus your phone. It's a wireless in-ear neckband headphone using Bluetooth 5.3 with a stable connection up to roughly 33 feet (10 meters), and it pairs with both iOS and Android devices by pressing a key. There's a microphone built in, and the package includes a USB charging cable plus a clip and a buckle for cable management.
What sets it apart from a generic neckband is the noise reduction figure: 29dB. That's a deliberate number aimed at machinery and power tools, which tells you exactly who this was designed for. Landscaping, welding, woodworking, farming, yard work — environments where constant engine and tool noise is the real enemy. The IPX5 rating covers damp, splashes, sweat and light rain, so it also holds up for fitness and running. Comfort gets real attention too: three-layer silicone earplugs, a lightweight low-profile band that can be concealed under a collar or protective clothing with only the earbuds showing. Battery is a 200mAh polymer lithium-ion cell rated for over 20 hours, and a 10-minute charge is claimed to give 2 hours of use. Warranty is 90 days from the manufacturer.
Buy it if you work in a loud industrial or outdoor trade and want one headset that pairs, blocks noise, survives sweat and rain, and lasts a full shift or more. Skip it if noise reduction and concealment aren't your priorities — a 29dB work-tuned headset is a specific tool, not a general-purpose music headphone. And skip it if you wanted an accessory for Shokz headphones; that's a different product entirely.
• Best for protecting Shokz OpenFit 2+ → PROfezzion Shokz OpenFit 2+. It's the only one of the two that touches those headphones.
• Best for noise reduction → Tangxi Neckband. 29dB is a real, stated figure; the PROfezzion case makes no audio claims because it isn't audio gear.
• Best for battery life → Tangxi Neckband. Over 20 hours from a 200mAh battery, plus a 10-minute charge for 2 hours of use.
• Best for water resistance in the field → a tie on paper. Both are rated IPX5, so both handle splashes, sweat and light rain — neither is rated for submersion.
• Best for drop protection → PROfezzion Shokz OpenFit 2+. Shockproof, dust resistant, secure locking latch, non-slip interior pad.
• Best for all-day wear under work clothing → Tangxi Neckband. The low-profile band hides under a collar and the three-layer silicone earplugs are built for long shifts.
• Best for wireless freedom → Tangxi Neckband. Bluetooth 5.3, 10-meter range, iOS and Android support.
• Best for a single-purpose purchase → PROfezzion Shokz OpenFit 2+. If you own OpenFit 2+ and nothing else, that's your pick.
These two don't actually compete for the same buyer, so my recommendation splits cleanly. If you already own Shokz OpenFit 2+ headphones, I'd buy the PROfezzion case — the locking latch and non-slip pad solve a real, everyday failure mode, and IPX5 plus shockproof construction is exactly what a case should offer. If you're starting from zero and need a headset for loud work or training, I'd buy the Tangxi Neckband: 29dB reduction, 20+ hours and IPX5 in one package is a coherent tool. Check the current price on Amazon for whichever one matches your situation before deciding.
FAQ
are headphones waterproof
Not in the way most people mean. Neither product here is rated for full submersion — both carry an IPX5 rating, which covers splashes, spills, sweat and light rain. If you need to swim with them, look for a higher IP rating.
are headphones water resistant
No. It's built only for the 2025 Shokz OpenFit 2+ (2 Plus). It's explicitly not compatible with the OpenFit Air (2024) or the OpenFit 1 (2023), so double-check your model before buying.
Over 20 hours per charge from the built-in 200mAh battery, and a 10-minute charge is stated to give 2 hours of use — handy if you forget to top it up before a shift.
