• POFENAL RDM2070D — biggest strength: a wired 2.5 mm jack earpiece with a D-shaped in-ear housing, inline PTT mic and passive noise cancellation, built specifically to pair with a long list of Motorola handheld radios.
• POFENAL RDM2070D — biggest trade-off: it is a communication accessory, not a music headphone. It needs a compatible radio to be useful, it is wired, and the manufacturer lists only a 1-month warranty.
• SAMVEK Swimming Headphones — biggest strength: IP68 waterproofing plus bone conduction and 32GB of built-in storage, so you can swim, run or ride with no phone nearby.
• SAMVEK Swimming Headphones — biggest trade-off: Bluetooth does not work underwater, so you must switch to MP3 mode before you submerge, and there is no active noise control — the open-ear design lets the world in by design.
• Who each pick is for: POFENAL for radio users, dispatchers, security and event staff who need hands-free talk on a CP200-style handheld. SAMVEK for swimmers, surfers, runners and cyclists who want one headphone for both dry land and water.
The RDM2070D is not really a "headphone" in the streaming-music sense. It is a single-wire surveillance-style earpiece with a push-to-talk microphone, terminated in a 2.5 mm jack. Its dynamic driver covers a 20 Hz to 20,000 Hz range, which is plenty for voice traffic, and the in-ear, D-shaped metal housing sits flush enough to stay discreet on a job.
Where it earns its keep is compatibility. POFENAL lists support across a very wide spread of Motorola handheld families — the CP series (CP040 through CP300), the GP and SP series, the XTN, AX/XV, XU, CLS and VL50 Spirit lines, and the MU and MV series. If you already own one of those radios, this is a drop-in accessory. The inline PTT module means you can key the mic without lifting the radio off your belt, and passive noise cancellation plus the in-ear seal help cut wind and traffic rumble when you are on a bike, on a site, or on a crowded event floor.
Who should buy it: anyone running one of those compatible Motorola radios who wants hands-free transmit. Riders on motorcycles or bicycles who carry a radio for group comms, security staff, warehouse and hospitality teams, and event crews will all get the point of it immediately.
SAMVEK Swimming Headphones: Who It's For
SAMVEK's X6 takes the opposite approach: no wires, no radio, just you and your music. The headline spec is IP68 waterproofing. That rating covers swimming, snorkeling, sweat and rain, and the company explicitly says it is designed to be worn with a swim cap, goggles and earplugs. It weighs 30 grams and uses an open-ear, bone conduction driver, so your ear canals stay clear and you keep hearing traffic, pool noise and voices around you.
The second headline is the 32GB of onboard memory. That is the piece that makes it work underwater, because Bluetooth simply does not transmit through water — SAMVEK says so plainly in its own notes, and instructs you to switch to MP3 mode before you go under. With 32GB you can load thousands of tracks (the listing cites figures in the 6,000-to-8,000-song range, depending on file size) in MP3, WMA, WAV, APE and FLAC. No phone, no watch, no armband.
On dry land it behaves like a normal sport headphone. Bluetooth 6.1 gives a 10-metre range and multi-device pairing, the button controls are glove-friendly, and the battery is rated at 8 hours of playback from a 2-hour charge. The adjustable headband is there to fit different head sizes, and the ABS/PC build is matte black.
Who should buy it: swimmers first, but also runners, surfers, gym-goers and cyclists who want one device that survives sweat and rain and still works in open air. The bone conduction design is a genuine safety argument for cycling — you hear the road.
Who should skip it: anyone who wants noise cancelling or deep isolation. The spec sheet lists no noise control, and open-ear bone conduction is the opposite of sealed. If you ride in loud traffic and want the world muffled, this is not that product. It is also the wrong pick if your real need is push-to-talk radio comms. And the warranty is a year, which is a more standard consumer term than the POFENAL's month.
Side-by-Side: Which Should You Choose?
• Best for radio push-to-talk → POFENAL RDM2070D. The inline PTT mic and 2.5 mm jack exist for exactly that.
• Best for swimming and underwater use → SAMVEK. IP68 and MP3 mode; Bluetooth is not usable underwater.
• Best for hearing your surroundings while cycling → SAMVEK. Open-ear bone conduction keeps your ears clear; the POFENAL, by contrast, seals in and cancels noise.
• Best for wind and traffic noise reduction → POFENAL. Its passive noise cancellation and in-ear D-shaped housing are built to cut ambient sound.
• Best for battery freedom → SAMVEK, with up to 8 hours per charge. The POFENAL draws power from the radio it plugs into, so it has no battery of its own.
• Best for riding with a group that uses handhelds → POFENAL, provided your radio is on its compatibility list.
• Best for a single device across pool, road and gym → SAMVEK. One headphone, waterproof, wireless, with onboard storage.
I would buy the SAMVEK Swimming Headphones. In my opinion, the 32GB of onboard storage plus IP68 waterproofing and open-ear bone conduction make it the more versatile product for 2026 — it covers cycling, running, the gym and the pool with one device, and the open design is the safer choice on a bike. The POFENAL RDM2070D is the better tool if, and only if, you are already carrying a compatible Motorola handheld and need push-to-talk. For everyone else, the SAMVEK is the pick I would recommend. Check the current price on Amazon before you commit, since both sit in very different accessory categories.
FAQ
can you bike with headphones
Yes, but the design matters. The SAMVEK's open-ear bone conduction leaves your ear canals clear, so you can still hear cars and other riders — it is rated IP68 for sweat and rain, with 8 hours of playback. The POFENAL RDM2070D uses an in-ear seal with passive noise cancellation, which is better for cutting wind noise but blocks more of the road around you.
Keep the volume low, keep one ear as open as possible, and pick gear that matches the job. If you want music, the SAMVEK runs in Bluetooth 6.1 mode with a 10-metre range, or in MP3 mode straight from its 32GB storage with no phone at all. If you need to talk to a group, the POFENAL plugs into a compatible Motorola radio and uses its inline PTT mic instead.
what are the best cycling headphones
It depends on what "best" means for your ride. For hearing traffic while you ride, I would point to open-ear bone conduction like the SAMVEK, which keeps your ears unblocked and survives sweat and rain. For cutting wind noise and staying in radio contact, the POFENAL RDM2070D's in-ear D-shaped housing and 2.5 mm radio connection are the more sensible fit.
can cyclists wear headphones
There is no hardware reason they cannot, and both of these are wearable on a bike. The real differences are practical: the SAMVEK is wireless, waterproof and self-contained with 32GB of storage and an 8-hour battery, while the POFENAL is a wired earpiece that only makes sense if you are carrying one of the compatible Motorola handhelds it lists.
