If you want a cycling earbud you can also swim laps with and recharge in minutes, choose DOOGEEEco Bone Conduction Headphones; if you want a straightforward open-ear hook design for long rides and the occasional swim, choose RELAXYO Swimming Bone Conduction.
• DOOGEEEco — biggest strength: A 32GB MP3 mode plus Bluetooth 5.4 multi-point pairing, wrapped in an IP68 shell with a silicone-and-titanium adjustable band that stays put through sweat and rain.
• DOOGEEEco — biggest trade-off: It's a bulkier banded design, and the noise control is listed as None, so you get full ambient sound whether you want it or not.
• RELAXYO — biggest strength: A lightweight open-ear hook shape in black, rated IPX8/IP68 for sweat, rain, surfing, fishing and hiking, and it plays nicely under a swim cap or goggles.
• RELAXYO — biggest trade-off: Fewer documented extras — no built-in memory figure beyond the 32GB MP3 mention, no multi-point pairing claim, and a shorter listed playtime of 7 hours.
• Who each pick is for: Cyclists who want phone-free music and fast top-ups → DOOGEEEco. Riders who want the simplest possible open-ear hook and don't mind shorter runtime → RELAXYO.
The DOOGEEEco pair is built around one idea: leave your phone behind and keep moving. The 32GB of built-in memory holds roughly 8,000 songs, so on a bike you can load a playlist once and ride without a phone in your pocket or a cable tugging at your jersey. When you do want Bluetooth, version 5.4 with multi-point connectivity lets it hop between a phone and a laptop, which is genuinely useful if you take calls at your desk between rides.
For cycling specifically, two things stand out. First, the physical buttons. Gloves on, hands wet from rain or sweat — you can still play, pause, skip and answer calls by feel instead of swiping at a touch panel. Second, the 10-minute quick charge that returns 2 hours of playback, which is the difference between salvaging a ride and skipping it when you forgot to plug in. The full charge takes about 2 hours and is rated at up to 10 hours of average life, though one bullet lists 7 hours of continuous playback — worth noting that real-world runtime sits somewhere in that range depending on volume and mode.
Who should skip it? If you want the smallest, lightest thing on your head and nothing more, the banded design is more hardware than you need. And if you rely on passive noise blocking for traffic-free focus, this isn't that — noise control is listed as None, and open-ear bone conduction is designed to let sound in.
RELAXYO Swimming Bone Conduction: Who It's For
The RELAXYO X7 takes the opposite approach: minimal, hook-shaped, open-ear, black, and easy to forget you're wearing. The earpiece shape is a hook, which tends to suit riders who wear helmets and sunglasses and don't want a band competing for space behind the head. It's rated IP68/IPX8 waterproof and the brand explicitly lists swimming, surfing, running, fishing and hiking as use cases, plus a note that it can be worn with a swim cap or goggles.
One operational detail RELAXYO calls out directly: switch from Bluetooth to MP3 mode before swimming, since Bluetooth doesn't travel through water. That tells you the 32GB MP3 storage is the mode that actually matters underwater, and it's the same basic workflow as the DOOGEEEco. Battery is rated at 7 hours of average life, which covers a long ride, a marathon or a multi-hour training block, but leaves less headroom than DOOGEEEco's 10-hour figure.
Bluetooth 5.4 is on board for wireless listening, and there's no headphone jack, so it's wireless-only. Warranty is listed as 1 year. Noise control is also None here, so expect the same open, ambient-aware listening experience — which is exactly what you want on a bike and exactly what you don't want on a noisy train.
Who should skip it? Anyone who wants documented extras like multipoint pairing, a quick-charge claim, or a stated memory capacity in songs. The RELAXYO sheet is leaner. It's also the pick to avoid if maximum runtime is your priority.
Side-by-Side: Which Should You Choose?
• Best for all-day battery → DOOGEEEco, with a 10-hour average life rating and a 2-hour full charge.
• Best for fast top-ups → DOOGEEEco. Ten minutes gets you 2 hours of playback.
• Best for the lightest, simplest fit → RELAXYO. A hook-shaped open-ear design that tucks under a helmet or swim cap with less hardware.
• Best for comfort with sensitive skin → DOOGEEEco, thanks to hypoallergenic silicone contact points and a flexible titanium alloy band.
• Best for swimming-first buyers → Both are IP68-class, but RELAXYO is the one whose marketing centers on the pool and surf; DOOGEEEco covers swimming plus a broader sport loadout.
• Best for multi-device switching → DOOGEEEco, which explicitly supports multi-point connectivity between phone and laptop.
• Best for a longer warranty → DOOGEEEco lists 2 years versus RELAXYO's 1 year.
In my opinion, the DOOGEEEco is the better cycling earbud of the two, and it's the one I'd buy. The MP3 mode plus 32GB of storage means you can ride phone-free, the 10-minute quick charge is a real-world lifesaver, and the multi-point Bluetooth, button controls and 2-year warranty round out a more complete package for someone who splits time between the bike and the pool. The RELAXYO is a solid, lighter alternative if you prefer a hook design and shorter, simpler spec sheet — but for most riders, DOOGEEEco covers more ground with fewer compromises.
For cycling, DOOGEEEco edges ahead because of phone-free MP3 playback, multi-point Bluetooth 5.4, physical buttons you can use with gloves, and a longer rated battery life. RELAXYO works fine on a bike too, but its spec sheet is simpler. If you want the most features per ride, go DOOGEEEco.
Yes — both are rated IP68/IPX8 for water protection. The key step on both is switching to MP3 mode before you get in the water, since Bluetooth signals don't carry underwater. RELAXYO specifically notes it can be worn with a swim cap or goggles.
DOOGEEEco lists up to 10 hours of average battery life with a 2-hour charge time and a 10-minute quick charge that yields 2 hours of playback. RELAXYO lists 7 hours. If runtime and fast charging matter to you, DOOGEEEco is the stronger choice.
Pricing changes often, so check the current price on Amazon using the button on this page rather than relying on any number here. In my opinion, DOOGEEEco justifies its place for cyclists who want MP3 storage, quick charging and a longer warranty, while RELAXYO suits buyers who want a lighter hook design and don't need the extras.
