If you want a lightweight everyday running headphone with the newest Bluetooth and fast-charge convenience, choose POPUX Bone Conduction Headphones; if you need one pair that also plays music underwater from built-in storage, choose Laoziniu Bone Conduction Swimming.
• POPUX Bone Conduction Headphones — biggest strength: Bluetooth 5.4 with dual-device connection, a 25 g wraparound titanium frame, IP66 sweat/rain protection and a 10-hour battery with 5-minute/2-hour fast charging. Biggest trade-off: it is not built for swimming — IP66 covers sweat and rain, not pool sessions, and it has no built-in music storage.
• Laoziniu Bone Conduction Swimming — biggest strength: IPX8 waterproofing plus a 32GB built-in MP3 player, so you can listen while swimming without a phone or a Bluetooth signal. Biggest trade-off: no Bluetooth version is specified, the frame is a bendable silicone wraparound at 30 g, and Bluetooth is only meant for dry-land use.
• Who POPUX is for: runners, cyclists and gym users who want a featherweight open-ear headphone that stays aware of traffic and swaps between two devices.
• Who Laoziniu is for: swimmers and water-workout users who want the same headphone to double as a running/commuting pair.
The POPUX pair reads like a running-first design. At 25 grams it is the lighter of the two, and the wraparound titanium frame is described as adjustable to fit different head shapes — that matters on a run, because a headphone that shifts when you turn your head is a headphone you stop wearing. The open-ear, bone-conduction driver keeps your ear canal clear, so traffic, bikes and other runners stay audible while music plays.
What stands out on the spec sheet is the connectivity and charging story. Bluetooth 5.4 is the newer wireless version here, and POPUX says it supports two simultaneous connections with switching between a phone and a laptop — genuinely useful if you take a call mid-run or move from treadmill to desk. The 200mAh battery is rated for up to 10 hours, and a 5-minute top-up is claimed to give 2 hours of playback. Physical push buttons are the control method, which is the right call for wet or gloved hands compared with touch panels.
Durability is IP66: fine for sweat, rain and hose-down, but not a swimming rating. Buy it if you run, cycle, hike, climb or train indoors and want an ultra-light open-ear headphone with modern Bluetooth and quick charging. Skip it if your main sport happens in a pool, or if you want to leave your phone behind entirely — there is no onboard storage, so POPUX needs a Bluetooth source.
The Laoziniu X7 solves a problem POPUX does not attempt: music in the water. IPX8 waterproofing is the key spec — that is the level associated with sustained immersion, which is why this pair is marketed for pool training and water workouts. Just as important, it carries 32GB of built-in memory and an MP3 mode, so you load songs and listen while swimming with no phone and no Bluetooth signal to lose.
On land it flips into a normal Bluetooth headphone for running, walking, cycling, gym work and commuting. The frame is a lightweight 30 g wraparound made of silicone, described as bendable and foldable to follow the curve of your head and easy to carry — a sensible choice for a device that lives in a swim bag. Laoziniu quotes a 2-hour full charge for up to 10 hours of use, and it charges over a magnetic cable.
Buy it if you swim and want one headphone to cover both the pool and the pavement, or if you like the idea of built-in storage as a phone-free backup. Skip it if Bluetooth is your priority: the listing does not specify a Bluetooth version, and the X7 is a heavier, softer-feeling fit than the titanium-framed POPUX. Also note the warranty is listed as 1 year versus POPUX's 2.
• Best for battery life → POPUX Bone Conduction Headphones (up to 10 hours, 200mAh, 5-minute charge for 2 hours).
• Best for swimming → Laoziniu Bone Conduction Swimming (IPX8 plus a 32GB MP3 player for phone-free underwater listening).
• Best for running and road awareness → POPUX — 25 g, adjustable titanium frame, open-ear design that keeps you aware of surroundings.
• Best for phone-free listening → Laoziniu, thanks to the 32GB of built-in storage.
• Best for connectivity → POPUX (Bluetooth 5.4, dual-device connection; Laoziniu's version is unspecified).
• Best for wet-hand controls → POPUX (physical push buttons; Laoziniu lists Bluetooth as the control type).
• Best for a one-headphone quiver → Laoziniu, if you swim and run; POPUX, if you only train on land.
• Best for lighter wear → POPUX at 25 g versus Laoziniu at 30 g.
I would buy the POPUX Bone Conduction Headphones for running. Bluetooth 5.4 with dual-device switching, physical buttons, 25 g on the head and a 5-minute charge that buys two hours of playback are exactly the traits that make a running headphone easy to live with, and IP66 covers sweat and rain. The Laoziniu earns its place only if you actually swim — then IPX8 and the 32GB MP3 mode outweigh everything else. If your training is land-only, POPUX is my pick; if the pool is part of your week, buy Laoziniu. Check the current price on Amazon before you commit.
what are the best bluetooth headphones for running
There is no single "best" — it comes down to fit and features. For running specifically, the POPUX Bone Conduction Headphones fit the brief well: 25 g, an adjustable titanium wraparound frame, open-ear design for awareness, Bluetooth 5.4 and up to 10 hours of battery. The Laoziniu Bone Conduction Swimming also works for running in Bluetooth mode, but its edge is water use, not road running.
what are the best bluetooth earbuds for running
If you specifically want earbuds that seal in your ears, neither of these is that — both are open-ear bone conduction headphones that leave the ear canal open. Between the two, POPUX is the more running-focused option thanks to Bluetooth 5.4, dual-device connection and physical push-button controls. Laoziniu is the better pick only if you also need IPX8 waterproofing and built-in MP3 storage.
No. If you run with your phone, Bluetooth mode is enough, and the POPUX Bone Conduction Headphones give you a newer Bluetooth version and dual-device switching. The Laoziniu's 32GB memory matters when you are underwater and cannot use Bluetooth — that is its real purpose.
Laoziniu Bone Conduction Swimming, clearly. It is rated IPX8 for pool training and water workouts and includes a 32GB MP3 player so music plays without a phone. The POPUX pair is IP66, which is aimed at sweat and rain, not immersion, so I would not swim in it.
