How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one pair of earmuffs that blocks loud machinery while streaming music, taking calls or tuning into FM/AM radio, choose PROHEAR 033; if you need headphones that survive being submerged in a pool and play from built-in memory while you swim, choose Clooissr 32GB. These two products look similar on a shelf — both are black, wireless, Bluetooth-enabled and open to the idea of protecting your ears — but they solve completely different problems. One is hearing protection with entertainment built in. The other is a waterproof audio player built for water and sweat. Pick the wrong one and you will be disappointed for reasons that have nothing to do with quality.
• PROHEAR 033 biggest strength: Certified hearing protection. It carries an NRR 25dB / SNR 30dB rating backed by ANSI S3.19-1974 and CE EN 352-1, which is the whole point of the product — the Bluetooth, radio and microphone are extras layered on top of real noise reduction.
• PROHEAR 033 biggest trade-off: It is a full over-the-head earmuff at 13.12 ounces with a bulky 8.31 x 6.34 x 4.21 inch shell. That is a lot of plastic and padding, and it is not something you would wear into a pool.
• Clooissr 32GB biggest strength: IPX8 waterproofing to 6ft (2m) with 32GB of internal storage, so it keeps playing when Bluetooth physically cannot travel through water.
• Clooissr 32GB biggest trade-off: It offers passive noise cancellation only and no certified noise reduction rating — it protects your ears by staying open, not by sealing sound out. And underwater you must use MP3 mode, not Bluetooth.
• Who PROHEAR 033 is for: Anyone mowing, snowblowing, woodworking or working around loud equipment who wants protection and audio in one unit.
• Who Clooissr 32GB is for: Swimmers, runners and cyclists who need audio that survives water and stays aware of traffic.
The PROHEAR 033 is, first and last, a piece of safety gear. Its 25dB NRR rating is certified to ANSI S3.19-1974 in the US and CE EN 352-1 in Europe, and that certification is the reason to buy it. Everything else — Bluetooth 5.4, the integrated microphone, the FM/AM radio — exists to make you actually want to put it on. That matters more than it sounds, because the best hearing protection is the pair you keep wearing.
The audio side is genuinely thought through. Bluetooth 5.4 gives a stable connection for streaming from a phone or tablet, and the multifunctional button plus built-in mic means you can take a call without pulling the earmuffs off. The radio section is unusually complete for this category: high reception sensitivity, automatic and manual station search, 10 AM and 10 FM presets, and an LCD display so you can see what you are tuned to. If you have ever mowed a lawn while listening to a football match through the commentary, you understand exactly who this is built for.
Who should skip it? Anyone shopping for swimming, running or gym audio. It is not waterproof, it is heavy, and its whole design assumes you are stationary around loud noise. One practical note: the charging port ships as either Type-C or 3.5mm at random as part of a 2.0 update, and both versions work identically.
Clooissr 32GB: Who It's For
The Clooissr 32GB is built around one hard physical fact: Bluetooth signals do not travel through water. So instead of pretending, Clooissr gave the B35 32GB of internal memory and an MP3 mode for underwater use, while Bluetooth handles everything above the surface. If you swim laps and want music, this is the design that actually works.
The waterproofing is the headline. It is certified to IPX8 and rated for submersion up to 6ft (2m), with a sealed structure and nano-hydrophobic coating to keep sweat and rain out too. Included swim earplugs block water from the ear canal, and stabilizing straps are supplied to lock the fit down further.
The fit engineering is more interesting than most bone conduction designs. Instead of the usual over-ear hooks and two-point clamping, the B35 uses a front cabin plus ear hook arrangement: the hook stabilizes on the auricle, the front cabin locks onto the ear bone, and the forces cancel each other out. Clooissr claims this reduces cheekbone pressure and cuts vibration by around 80% through low-frequency conduction technology — the practical benefit being less of that buzzing ache long bone conduction sessions can produce.
Sound comes from 12mm drivers with what the brand describes as rich bass and clear mids, plus a built-in mic for Bluetooth calls. The open-ear design keeps you aware of traffic and surroundings, which is why it suits running and cycling as much as swimming. It weighs 24.95g (0.8oz), the frame uses titanium memory alloy rated to 12,000 bend tests, and magnetic charging takes 2 hours for 8–10 hours of playback. A 2-year warranty is included.
Side-by-Side: Which Should You Choose?
• Best for certified hearing protection → PROHEAR 033. NRR 25dB / SNR 30dB, certified to ANSI and CE standards.
• Best for swimming → Clooissr 32GB. IPX8 to 6ft with 32GB of MP3 storage for underwater playback.
• Best for long sessions on one charge → PROHEAR 033. 48 hours Bluetooth, 40+ hours in wired/radio mode.
• Best for running and cycling → Clooissr 32GB. Open-ear awareness, 0.8oz, multi-point stable fit.
• Best for mowing, snowblowing, woodworking → PROHEAR 033. That is precisely its stated use case, radio included.
• Best for taking calls → either. Both have a built-in microphone and Bluetooth — 5.4 on the PROHEAR, 5.3 on the Clooissr.
• Best for durability against sweat and rain → Clooissr 32GB. Sealed IPX8 body versus a padded earmuff not rated for water.
• Best for hot, humid workouts → Clooissr 32GB. Open-ear means no trapped heat; the PROHEAR is over-the-head with full cushions.
In my opinion, most people searching this comparison want the PROHEAR 033. If your noise problem is a lawnmower, a snowblower, a table saw or a workshop, certified 25dB reduction plus 48 hours of Bluetooth and a built-in radio is a genuinely useful combination, and nothing about the Clooissr matches it there. I would only steer you to the Clooissr 32GB if water is non-negotiable — if you swim laps and want music with you, its IPX8 rating and 32GB of internal storage are the reason it exists, and no amount of noise reduction substitutes for that. Decide which of those two sentences describes your week, and the choice is easy.
FAQ
No. The PROHEAR 033 is not rated for water and is designed as over-the-head earmuffs for noisy environments. The Clooissr 32GB is the one certified to IPX8 for submersion up to 6ft.
No — Bluetooth signals do not travel through water, so you must switch to MP3 mode while submerged. Above water, both Bluetooth 5.3 and MP3 playback work normally. You load music into the 32GB memory from a computer.
