• Piegricdiat's biggest strength: IPX8 deep-waterproofing plus 32GB of onboard MP3 storage, so you can swim, surf or snorkel with music and leave your phone on the shore.
• Piegricdiat's biggest trade-off: Roughly 6 hours of battery life and a plastic build — fine for a session, not for a full day.
• DOOGEEEco's biggest strength: Up to 10 hours in Bluetooth mode, a 25-gram titanium-alloy frame, Bluetooth 5.4 with multipoint, and a fast-charge top-up that adds two hours from ten minutes on the cable.
• DOOGEEEco's biggest trade-off: IP68 is built for water too, but the shorter 6-hour MP3 playback is the mode you'll actually lean on in the pool.
• Pick Piegricdiat if you want maximum underwater confidence and a big local library you can carry without a phone.
• Pick DOOGEEEco if you want lighter, longer-lasting all-day wear and the latest Bluetooth conveniences.
The Piegricdiat X16 is built around one idea: keep your ears open and your music with you, even when you're in the water. It uses open-ear bone conduction drivers rated 8 ohm with a 20 Hz–20,000 Hz frequency range, so nothing sits inside your ear canal. That's the core appeal of the format — you stay aware of traffic, trail noise and people around you while audio plays, and your ears don't get sore from being plugged for hours. The DeepBlack plastic housing keeps the weight reasonable, and the physical button controls are the kind you can operate by feel with wet or gloved hands.
What separates it from most bone conduction sets is the IPX8 rating. That's genuine deep-waterproofing, and the brand explicitly supports swimming, surfing and snorkeling — with the caveat that it shouldn't stay submerged for more than six hours at a stretch. Paired with the built-in 32GB of memory, that means you can copy your music over with the included magnetic charging cable, treat the headset like a USB drive, and swim laps without carrying a phone or worrying about Bluetooth dropping out underwater. Bluetooth 5.3 is there for everything above the surface, with a stable, low-latency connection and a noise-reduction microphone for calls.
DOOGEEEco Bone Conduction Headphones: Who It's For
The DOOGEEEco set — model BONEBEATSWIMLITE — leans into endurance and comfort. It's rated IP68, so it handles underwater swimming, rain and the bathroom shower just as confidently in practice, and the bone conduction driver keeps the open-ear, ears-clear philosophy intact. The difference is in how it's built: a flexible titanium alloy frame at just 25 grams, with an adjustable strap that rotates and sizes to different head shapes. In my opinion that's the more comfortable of the two for long sessions, and titanium alloy resists the bending and deformation that eventually catches up with plastic frames.
Battery is where it pulls clearly ahead. Up to 10 hours in Bluetooth mode, 6 hours in MP3 mode, and a 200mAh fast-charge system that gives you roughly two hours of playback from a ten-minute top-up. That fast-charge trick matters more than it sounds — it's the difference between a dead headset on the way out the door and one that survives your workout. Bluetooth 5.4 adds multipoint, so it switches between your phone and laptop without you re-pairing, and the low-latency chip keeps audio and video in sync.
Sound is described as bass-forward with clear treble, there's a noise-cancelling microphone for calls, and the physical buttons work when your hands are wet or mid-stride. The 32GB of storage holds roughly 8,000 songs for phone-free MP3 listening.
Who should buy it: runners, gym-goers, hikers and cyclists who want all-day battery, plus swimmers who value a light, adjustable fit. Who should skip it: anyone who wants the absolute deepest submersion headroom — IP68 is excellent, but IPX8 is the stronger claim for serious underwater time — and anyone who'd rather not deal with the shorter 6-hour MP3 mode.
Side-by-Side: Which Should You Choose?
• Best for battery life → DOOGEEEco Bone Conduction Headphones. 10 hours Bluetooth vs roughly 6 on the Piegricdiat.
• Best for comfort over long wear → DOOGEEEco. 25 grams, titanium alloy, adjustable rotating strap.
• Best for phone-free music → a tie on storage, DOOGEEEco on convenience. Both offer 32GB; DOOGEEEco's 6-hour MP3 mode outlasts typical pool sessions more gracefully.
• Best for the newest wireless features → DOOGEEEco. Bluetooth 5.4 with multipoint beats Bluetooth 5.3 without it.
• Best for quick top-ups → DOOGEEEco. Ten minutes of charging yields about two hours of playback.
• Best for awareness and safety while moving → either. Both are open-ear bone conduction, so both keep you tuned into your surroundings.
• Best for a simple, swim-first setup → Piegricdiat. IPX8 plus 32GB in one no-nonsense package.
I'd buy the DOOGEEEco Bone Conduction Headphones. The 10-hour battery, 25-gram titanium frame, Bluetooth 5.4 multipoint and fast charging cover more of my week — runs, gym, commutes, calls — than a swim-first headset would. The IP68 rating still handles pool laps and rain, and 32GB of MP3 storage keeps the phone-free option open. I'd only switch to the Piegricdiat if deep, extended underwater use were my main activity, since IPX8 is the stronger submersion claim there. For most people balancing several sports and a full day, DOOGEEEco is the more versatile pick.
Both are built for water. Piegricdiat carries the more aggressive IPX8 deep-waterproofing claim and shouldn't stay submerged more than six hours continuously. DOOGEEEco is IP68 and rated for underwater swimming, rain and showers. For long, repeated submersion, I'd lean Piegricdiat; for mixed pool and land use, DOOGEEEco.
How long does the battery last on each?
Yes — both have 32GB of onboard memory and an MP3 mode. DOOGEEEco's storage is described as holding around 8,000 songs. You copy music over via the supplied cable and play without pairing a phone.
DOOGEEEco. It uses Bluetooth 5.4 and supports multipoint, so it switches between a phone and a laptop. Piegricdiat uses Bluetooth 5.3, which is stable and low-latency but lacks the multipoint feature. Check the current price on Amazon before deciding, since both are sold there.
