• Gigastone 4PK — biggest strength: a neckband design with 10 hours of music playtime and a claimed 240–250 hours of standby, so it can sit ready for days between charges. In my opinion that standby figure is the headline number here.
• Gigastone 4PK — biggest trade-off: it is a neckband, not true wireless, so there is a band around your neck and no charging case to pocket. Bluetooth 5.0 is also a generation behind.
• SGNICS Pine64 — biggest strength: true wireless earbuds with a charging case, 13 mm dynamic drivers, Bluetooth 5.3 and a combined 31 hours of battery life (7 hours per charge plus case top-ups).
• SGNICS Pine64 — biggest trade-off: the buds themselves only run about 7 hours before they need the case, and the 3.8 g in-ear fit is a personal thing — some ears love it, some don't.
• Who each pick is for: Gigastone 4PK for commuters, office users and runners who want one grab-and-go headset with marathon standby; SGNICS Pine64 for anyone who prefers pocketable true wireless with a case and wants the newer Bluetooth spec.
The Gigastone 4PK is built around one idea: keep a headset on your body, ready to go, without thinking about charging. The ergonomic neckband rests on your shoulders, so the earpieces hang there instead of living in a case. Magnetic tips are part of the design, which is a nice touch for keeping the two earpieces together when they're not in your ears. Bluetooth 5.0 handles the wireless connection, and A2DP stereo sound means it's aimed at everyday music and calls rather than audiophile listening.
The numbers that matter most are the battery figures. Gigastone lists 10 hours of music playback and 240–250 hours of standby. In practice, that combo means you can charge it, toss it in a bag, and not think about it again for days — a genuinely useful trait if your headphones sit idle between commutes or gym sessions. The IPX4 rating covers sweat, rain and splashing water, which is exactly the level of protection you want for workouts and drizzly walks (more on what IPX4 really means in the FAQ below).
Who should buy it? I'd point to three groups: people who run or train and want something that won't fall out, office and desk workers who take a lot of calls, and anyone who hates hunting for a charging case. The neckband format is also friendlier for glasses wearers and people who find in-ear buds uncomfortable over long stretches. It's sold as a 4-pack (four items), which suits a household or someone who wants a spare set in a different bag. The 1-year Gigastone manufacturer warranty with replacement coverage is a reasonable safety net.
Who should skip it? If you want the smallest possible footprint, a neckband is more hardware than true wireless buds. If you care about having the newest Bluetooth generation, 5.0 is older than 5.3. And if you specifically want a charging case with automatic re-pairing, that's the other product's territory.
The SGNICS Pine64 is a classic true wireless setup: two in-ear buds plus a charging case. The buds use 13 mm compound-diaphragm dynamic drivers, which is on the larger side for earbuds — bigger drivers generally move more air and tend to give you fuller low-end and more detail in the mix. Bluetooth 5.3 is the newer chip here, and SGNICS claims lower power consumption plus a stable signal within about 12 meters. If you've ever had buds stutter when you walk away from your phone, that range and stability claim is the spec to care about.
Battery works differently than the Gigastone. Each bud runs about 7 hours, and the case holds enough charge to refill them roughly three to four times, for 31 hours total when you're using both buds. That's a case-based model: shorter single sessions, but you top up on the go without a cable. The case also auto-reconnects to the last device you used when you open it — first pairing is manual, after that it's automatic. Touch controls handle play/pause, calls and voice-assistant wake-up, so there are no physical buttons to press.
Comfort-wise, the in-ear design with 3.8 g buds is light, and the ABS+PC housing in black is about as neutral as it gets. SGNICS lists the intended audience as teens, seniors and adults, and the box includes a cable, ear cushions and a manual. ENC (environmental noise cancelling) on the mic is aimed at making your voice clearer on calls rather than silencing the world around you.
Who should buy it? Anyone who wants pocketable earbuds, prefers touch controls over buttons, wants a newer Bluetooth chip and likes the idea of a case that keeps everything together and recharges on the move. Who should skip it? If you know in-ear buds irritate your ears, or you'd rather not manage a case at all, the neckband style is the safer bet. And if you want maximum single-session battery without touching a case, 7 hours per bud is the limit.
• Best for standby battery → Gigastone 4PK (240–250 hours standby vs. a case-based 31-hour total).
• Best for longest single charge → Gigastone 4PK (10 hours of continuous music vs. about 7 hours per SGNICS bud).
• Best for total battery with a case → SGNICS Pine64 (31 hours using both buds with case top-ups).
• Best for newest Bluetooth → SGNICS Pine64 (Bluetooth 5.3 vs. 5.0).
• Best for sound hardware on paper → SGNICS Pine64 (13 mm compound dynamic drivers).
• Best for workouts and sweat → Gigastone 4PK (IPX4 plus a secure neckband that won't drop out of your ears).
• Best for travel and pockets → SGNICS Pine64 (true wireless buds in a charging case).
• Best for hands-free calls and voice assistants → SGNICS Pine64 (ENC mic and touch control with assistant wake-up).
If I had to pick one for myself, I'd take the SGNICS Pine64. In my opinion the combination of Bluetooth 5.3, 13 mm drivers, touch controls and a charging case makes it the more modern, more flexible everyday headset — and 31 hours of total listening with auto-reconnect is plenty for most people's week. I'd choose the Gigastone 4PK instead if my priority were a headset that never needs a case, survives sweaty sessions on my neck, and sits charged for days thanks to that enormous standby figure. Both are IPX4, so the waterproofing isn't the deciding factor — the format is.
can i wear waterproof headphones in the shower
IPX4 means protection from sweat, rain and splashing water — not immersion. Both of these are rated IPX4, so they can handle splashes and damp conditions, but showering puts them under direct, sustained water contact that IPX4 doesn't cover. If you want shower-safe audio, look for a higher IP rating.
are headphones waterproof
Not all of them. Waterproofing is rated on the IP scale, and IPX4 — the rating on both the Gigastone 4PK and SGNICS Pine64 — means splash-resistant, not submersible. Treat IPX4 as "safe from sweat and rain," and treat anything you'd fully dunk as a different category.
For running, I'd lean Gigastone 4PK. The neckband keeps the earpieces anchored, IPX4 handles sweat, and 10 hours of playback covers even long training sessions. The SGNICS Pine64 works too, but in-ear buds can loosen with heavy movement.
It depends how you measure it. Gigastone 4PK wins on continuous playback (10 hours) and standby (240–250 hours). SGNICS Pine64 wins on total capacity with its case (31 hours across both buds). For a single long session, pick Gigastone; for all-week pocketable top-ups, pick SGNICS.
