If you want a pair of IPX4 waterproof earbuds with a massive 36-hour playback reserve for streaming, choose VOLT PLUS TECH PRO; if you need IPX8 swimming-grade bone conduction headphones with a built-in 32GB MP3 player, choose Laoziniu Bone Conduction Headphones.
• VOLT PLUS TECH PRO — biggest strength: A 2,000mAh charging case that delivers up to 36 hours of total listening, plus an LED screen that shows the exact power level of both the case and the buds.
• VOLT PLUS TECH PRO — biggest trade-off: IPX4 only means splash and sweat resistance, so it handles rain and gym sweat but not swimming or full submersion.
• Laoziniu Bone Conduction Headphones — biggest strength: IPX8 waterproofing and a 32GB MP3 player that lets you leave your phone behind entirely when you swim or train.
• Laoziniu Bone Conduction Headphones — biggest trade-off: Only 10 hours per charge, and Bluetooth does not transmit underwater, so you have to switch to MP3 mode in the pool.
• Who VOLT PLUS TECH PRO is for: Anyone who wants a wireless headset for streaming, long calls and all-day listening without hunting for a charger.
• Who Laoziniu Bone Conduction Headphones is for: Swimmers, runners and cyclists who want open-ear awareness and a phone-free music mode.
The VOLT PLUS TECH PRO is built around endurance. The charging case packs a 2,000mAh battery and the brand claims up to 8 recharges, which adds up to roughly 36 hours of total playtime with 6–8 hours per session. In practice, that means you can stream for a full workday, commute, and evening without touching a wall outlet. The LED display on the case is a small thing that turns out to matter a lot: it shows the actual power level of the box and the earbuds, so you are never guessing whether you have juice left before a long trip or a live session.
For streaming specifically, this is the pick I would lean toward. The Bluetooth 5.3 chip handles a stable wireless connection, the touch controls let you skip tracks, adjust volume and wake the buds with one tap, and CVC 8.0 noise reduction with a quad-mic setup is aimed squarely at keeping your voice clear on calls and streams in noisy rooms. There is also an 8D bass mode and a dynamic driver with a 20Hz–48kHz frequency range, which is a wide spec on paper for a set of in-ear buds. The white aluminum-and-plastic build feels like a daily-driver design rather than a rugged sports tool.
Laoziniu Bone Conduction Headphones: Who It's For
The Laoziniu set is a different animal. It uses bone conduction drivers that sit on your ear rather than inside it, so your ear canal stays open and you keep awareness of cars, other runners, and whatever is happening around you. At 30 grams with a titanium band, it is designed to be forgotten on your head during long sessions. The brand lists it as comfortable for running, cycling, walking and workouts, and that open-ear design is the whole reason it works for those activities.
The headline feature is IPX8 waterproofing. That is a genuine submersion rating, which is why Laoziniu markets these as swimming headphones for pool use and surfing. There is one honest caveat the brand itself states: Bluetooth does not travel through water, so when you swim you switch to the built-in 32GB MP3 player, which holds roughly 8,000 songs. In MP3 mode you do not need a phone at all, which is a real advantage at the pool or on a trail where you would rather not carry one. When you are out of the water, Bluetooth 5.3 gives you a stable connection up to about 33 feet in open space, and there is a built-in mic for calls.
The trade-offs are clear. Battery life is 10 hours per charge with about 2 hours to refill, which is fine for workouts but far short of the Volt's reserve. There is no active noise cancellation — the brand lists noise control as none, which is intentional for an open-ear design. You also need to dry the magnetic charging contacts completely before charging after water use, or you risk shortening the battery's life. Skip these if you want sealed, noise-reducing earbuds for streaming or if you need marathon battery life.
Side-by-Side: Which Should You Choose?
• Best for all-day battery life → VOLT PLUS TECH PRO. Up to 36 hours total via the 2,000mAh case versus 10 hours on a single Laoziniu charge.
• Best for streaming and calls → VOLT PLUS TECH PRO. Quad-mic setup with CVC 8.0 noise reduction, touch controls, and a Bluetooth 5.3 chip tuned for stable wireless audio.
• Best for phone-free training → Laoziniu. The onboard 32GB player means no phone required for roughly 8,000 songs.
• Best for situational awareness → Laoziniu. Open-ear bone conduction keeps your ears free so you hear traffic and surroundings.
• Best for rain and gym sweat → Either, with a caveat. Volt's IPX4 covers splashes and sweat; Laoziniu's IPX8 covers far more, but you must dry the contacts before charging.
• Best for noise reduction → VOLT PLUS TECH PRO. It has active noise cancellation; the Laoziniu has none by design.
• Best for comfort over long sessions → Laoziniu on paper. 30 grams and a titanium open-ear band is a lighter, less intrusive fit than in-ear buds.
In my opinion, if your priority is a wireless headset for streaming — long sessions, clear mic pickup, and not worrying about the battery dying mid-stream — I would buy the VOLT PLUS TECH PRO. The 36-hour case, LED power display and quad-mic noise reduction simply fit that job better. I would only steer you to the Laoziniu Bone Conduction Headphones if swimming, surfing or phone-free outdoor training is your main use, because IPX8 and the 32GB MP3 player are things the Volt cannot match. Two different jobs, two different answers — pick the one that matches yours.
It depends on the rating, not the word "waterproof." The Laoziniu set carries an IPX8 rating and is designed for pool and surf use, so shower exposure is within its design intent — but you should dry the charging contacts completely before charging. The VOLT PLUS TECH PRO is rated IPX4, which covers splashes and sweat rather than direct, sustained water exposure, so I would not plan on showering in it.
Not all of them — the rating tells you the truth. IPX4, like the Volt's, means resistance to splashes and sweat from any direction. IPX8, like the Laoziniu's, means the headphones can be submerged, which is why they are marketed for swimming. Always match the rating to how wet you actually plan to get.
The Laoziniu pair does, but not over Bluetooth — Bluetooth signals do not transmit through water. You switch to the built-in 32GB MP3 player instead, which is exactly why Laoziniu includes it. That is the mode to use in the pool.
For streaming, I would pick the VOLT PLUS TECH PRO. Its quad-mic array with CVC 8.0 noise reduction, touch media controls and up-to-36-hour case reserve are built for long wireless sessions. The Laoziniu is better suited to swimming and open-ear outdoor training than to sitting at a desk and streaming. If price matters to you, check the current price on Amazon for both before deciding.
