• VOLT PLUS TECH PRO — biggest strength: a 2,000mAh power-bank charging case that pushes total playback to a claimed 36 hours, plus IPX4 protection, CVC 8.0 noise reduction and a quad-mic setup for calls.
• VOLT PLUS TECH PRO — biggest trade-off: they are true in-ear buds, so they block your ears and your awareness of traffic, and "IPX4" means splash and sweat resistance only, not swimming.
• Sowmow Audio Glasses — biggest strength: open-ear speakers in a 37g glasses frame with Bluetooth 5.4, so you hear your music and the world around you at the same time.
• Sowmow Audio Glasses — biggest trade-off: no noise cancellation, no charging case, and roughly 8.5 hours per charge with a 3-hour top-up, so heavy all-day listeners will be reaching for the cable.
• Who each pick is for: VOLT PLUS TECH PRO is for the gym-and-commute listener who wants long runtime and isolation; Sowmow is for the walker, cyclist or driver who wants music without shutting the world out.
The headline number here is battery. VOLT PLUS TECH PRO ships with a 2,000mAh case that the spec sheet describes as good for up to 8 charges of 6–8 hours each, adding up to a 36-hour total figure. That is the sort of runtime that suits someone who is genuinely bad at remembering to charge things — a week of gym sessions, a long-haul flight, a festival weekend. The case doubles as a power bank and carries an LED display that shows the remaining power level for both the case and the buds, so you can see what's left instead of guessing.
On the audio and call side, the sheet lists Bluetooth 5.3, 25.94 ohm impedance, a 20Hz–48kHz frequency range, dynamic drivers, touch controls, and active noise cancellation with CVC 8.0 intelligent noise reduction across a quad mic. Touch control also handles track skipping and volume, which means you rarely need to touch your phone mid-workout. The IPX4 rating is explicitly framed as everyday-life waterproofing — rain, sweat, gym — not submersion.
So who should buy it? In my opinion, anyone whose priority list starts with runtime, then isolation, then call clarity in noisy places. The in-ear fit plus ANC is exactly what you want on a plane, a train or a busy office. Who should skip it? Anyone who hates things inside their ears, anyone who needs to hear traffic while running outdoors, and anyone who wants the open, airy feel of a speaker near — but not in — their ear canal. It's also worth remembering that 36 hours is a combined case-plus-buds figure, not 36 hours from a single charge. If price matters to you, check the current price on Amazon before deciding.
Sowmow takes the opposite approach. These are glasses first and headphones second: a 37g frame in Space Black with a frosted ABS build and AC sunglasses lenses, with speakers that sit outside your ear canal rather than inside it. The whole pitch is situational awareness. You can take a call or listen to a podcast on a walk, a commute or a bike path and still hear cars, other people and your surroundings. For a lot of outdoor listeners that is not a nice-to-have, it is the reason they stopped wearing buds outside in the first place.
The spec sheet lists Bluetooth 5.4 — a newer version than the Volt's 5.3 — with compatibility across iOS, Android and Windows, and up to 8.5 hours of playback per charge with a 3-hour recharge over USB-C. Controls are physical buttons rather than touch, which the sheet frames as a deliberate choice to cut down on accidental taps. That is a real advantage when you're moving: no phantom pauses because a gust of wind or a hat brim brushed the earbud. You also get the full package — glasses, Type-C cable, manual, inner box, PE bag and color box.
Two things to be honest about. There is no noise cancellation here at all, so in a loud environment your music competes with the world. And the IPX4 rating is described as sweat and light-splash resistant, with an explicit note that these are not waterproof and should be dried before charging. Who should buy it? In my opinion, walkers, runners who stay on quiet paths, cyclists, delivery riders, and anyone who wears sunglasses anyway and would rather not add a second thing to their head. Who should skip it? Anyone who wants deep, isolated bass, anyone who needs all-day runtime without charging, and anyone who wants a charging case to top up on the move — there isn't one.
Side-by-Side: Which Should You Choose?
• Best for battery life → VOLT PLUS TECH PRO. 36 hours combined with a 2,000mAh charging case versus 8.5 hours per charge and no case.
• Best for noisy environments and calls → VOLT PLUS TECH PRO. Active noise cancellation plus CVC 8.0 noise reduction and a quad mic array.
• Best for wearing all day without ear fatigue → Sowmow Audio Glasses. 37g open-ear frame versus in-ear tips that sit in the canal for hours.
• Best for low-fuss controls while moving → Sowmow Audio Glasses. Physical buttons are less prone to accidental touches than the Volt's touch panel.
• Best for newer wireless standard → Sowmow Audio Glasses. Bluetooth 5.4 versus Bluetooth 5.3 — a small generational step, not a night-and-day difference.
• Best for charging convenience on the go → VOLT PLUS TECH PRO. The case recharges the buds repeatedly; the Sowmow needs a wall or power bank via USB-C.
• Best for glasses wearers who want one device → Sowmow Audio Glasses. Sunglasses and audio in a single frame.
I would buy the VOLT PLUS TECH PRO. For me the deciding factor is the combination of a 36-hour total runtime with a self-charging power-bank case, active noise cancellation and a quad mic — that covers the gym, the commute and the flight without me thinking about a charger. The Sowmow is the smarter pick if awareness and all-day comfort matter more to you than isolation and runtime, and I genuinely rate the button controls and the 5.4 radio. But for the widest range of everyday situations, the Volt wins it.
can i wear waterproof headphones in the shower
With an IPX4 rating like both of these carry, no — that is splash and sweat resistance, not protection from a direct stream of water. Sowmow's own product information states the glasses are not waterproof and should be dried before charging. Keep IPX4 gear out of the shower and rinse-free.
are headphones waterproof
Most earbuds and audio glasses marketed for sport are water resistant, not waterproof. IPX4 specifically covers sweat and light splashes from any direction; it does not cover submersion or pressurized water. If you need swimming-grade protection, look for a higher IP rating than either product here offers.
For safety, Sowmow Audio Glasses — the open-ear design keeps you aware of traffic while the AC lenses cut glare. VOLT PLUS TECH PRO's in-ear fit and active noise cancellation isolate you from your surroundings, which is great indoors but a real consideration on a road.
That depends on your use. Sowmow lists up to 8.5 hours per charge with a 3-hour recharge time, so a daily walk or commute is fine for several days. VOLT PLUS TECH PRO stretches further because its 2,000mAh case recharges the buds on the move, up to a 36-hour total figure.
