• Philips T4506 — biggest strength: true wireless earbuds with active noise cancelling, a 10 mm dynamic driver, Bluetooth 5.1-class wireless (listed as Bluetooth 5), and up to 24 hours of total playtime with the charging case.
• Philips T4506 — biggest trade-off: IPX4 only. That means sweat and light rain are fine, but a lap pool is not. It's also in-ear, so you need a good ear-tip seal to get the sound and call quality you paid for.
• GREYOLK Swimming Headphones — biggest strength: IP68 waterproofing plus a bone-conduction open-ear design and 32GB of built-in MP3 memory, so you can swim with no phone anywhere near the water.
• GREYOLK Swimming Headphones — biggest trade-off: bone conduction trades bass depth and isolation for safety and waterproofing. It's also button-controlled, with no ANC that works like the Philips' ear-cup mic array.
• Who each pick is for: Philips T4506 for the desk-and-commute listener who wants ANC, touch controls and a charging case. GREYOLK for the swimmer, runner or cyclist who needs water and awareness more than immersion.
The T4506 is a classic true-wireless earbud, and its headline feature is active noise cancelling. Internal mics in the ear cups filter out steady background sound, which is exactly what you want when you're trying to focus on a spreadsheet or a call while a fan, a train or an open office hums around you. The 10 mm dynamic drivers and 20 Hz–20,000 Hz frequency range put it in normal, full-range earbud territory — not a specialist tuning, just a broad everyday curve.
The fit is silicone ear tips in three sizes, and Philips is unusually explicit about why that matters: if the tips don't seal your ear canals properly, both sound quality and call performance suffer. That's not a flaw, it's physics, but it does mean the T4506 rewards a few minutes of tip-swapping. In my opinion, this is the better pick if your listening happens at a desk, on transit or on calls — especially paired with a MacBook. For a laptop-first listener chasing the best hi-res-style everyday earbud experience, the ANC, the low 30 ms latency figure and the case-based charging are the reasons to choose it. Skip it if your main use is swimming or if you hate the sealed-in feeling of in-ear tips.
GREYOLK Swimming Headphones: Who It's For
The GREYOLK set is a different animal entirely. It's an open-ear, bone-conduction headset rated IP68, which the brand describes as completely waterproof, sweatproof, rainproof and dustproof. That rating is the whole point: this is a headset designed to go under water, and GREYOLK specifically notes it can be worn with a swim cap, goggles and earplugs. The bone-conduction driver vibrates against your cheekbone instead of firing into your ear canal, which is why the design can stay open and still deliver audio.
The second big idea is the built-in 32GB of memory. You load up to roughly 6,000 songs in MP3, WMA, WAV, APE or FLAC, double-click the power button to switch between Bluetooth and MP3 mode, and swim with zero devices nearby. That's a genuinely different workflow from any earbud that needs a paired phone within 10 metres. Speaking of Bluetooth, the sheet lists 5.3 in the feature bullets and 5.4 in the spec block — either way it's a current-generation chip with a 10-metre range, and a magnetic charging cable doubles as the data connection so your computer sees the headset as a memory disk for dropping files onto it.
Battery is a 150 mAh cell: 1.5 hours to charge, up to 8 hours of playback or talk time. It weighs 32 grams and uses a wraparound titanium frame, which is how open-ear headsets stay put during hard training. The trade-off is real, though. Bone conduction simply cannot produce the deep bass or the noise isolation of an in-ear bud with ANC, and the button controls are more deliberate than touch. I recommend the GREYOLK for swimmers, snorkelers, runners and cyclists — anyone who wants music plus full awareness of traffic and surroundings. If you want to disappear into a mix on a plane, this isn't it.
• Best for noise cancelling → Philips T4506. It's the only one of the two with real active noise cancelling built around in-ear mics.
• Best for actual swimming → GREYOLK Swimming Headphones. IP68 versus IPX4 is not a close call; the GREYOLK is built for immersion.
• Best for phone-free workouts → GREYOLK. 32GB of onboard memory means you can leave the phone in the locker.
• Best for MacBook calls and video meetings → Philips T4506. Instant pairing, touch call controls and a low 30 ms latency figure suit laptop audio and video.
• Best for total battery life → Philips T4506. Up to 24 hours with the case versus 8 hours from the GREYOLK's 150 mAh cell.
• Best for situational awareness → GREYOLK. The open-ear design keeps traffic, trails and poolside noise audible.
• Best for a secure sealed fit → Philips T4506. Three sizes of silicone tips let you tune the seal, which the brand says is critical for sound and calls.
• Best for runners and cyclists → GREYOLK. The 32-gram titanium wraparound frame and IP68 rating are aimed squarely at sport.
If I had to pick one for a MacBook-centric life, I'd buy the Philips T4506. ANC, touch controls, a charging case and up to 24 hours of playtime make it the more useful everyday headset for a laptop, and the 30 ms latency figure is the kind of detail that matters for video. The GREYOLK is the better product for one specific job — being underwater — and if that's your job, IP68 plus 32GB of MP3 memory is the combination you actually need. The honest answer is that these two barely compete: one is a noise-cancelling commuter bud, the other is a waterproof sport headset. Buy for the environment you'll actually use them in.
can i wear waterproof headphones in the shower
Yes, if the rating supports it. The GREYOLK's IP68 rating covers full water exposure, so shower use is within its design intent. The Philips T4506 is IPX4, which handles sweat and rain but is not rated for direct streams of water, so I would not shower in it.
are headphones waterproof
Not automatically. Water resistance is a rating, not a category. IPX4 on the Philips means splash and sweat protection; IP68 on the GREYOLK means dust-tight and protected against continuous immersion. Always match the rating to the activity rather than the word on the box.
The GREYOLK, without hesitation. It's the one with the IP68 rating, the bone-conduction open-ear design and the 32GB MP3 mode that lets you swim without a phone. The Philips is an IPX4 in-ear bud meant for commuting and desk work.
Yes — use the current price on Amazon before deciding, since both sit in different budget tiers and the value calculation changes as they move. Compare what each spec sheet gives you, then let the live price settle it.
