If you want an all-in-one audio solution for workouts and calls, choose BEARTWO Headphones; if you need a secure, water-resistant way to carry your phone and small essentials while you run, choose HAISSKY Running Armband. These two products solve completely different problems, and picking the right one comes down to whether you're missing sound or missing storage.
• BEARTWO Headphones – biggest trade-off: It's an audio device only — it won't hold your phone, keys, or cards, and the Bluetooth 4.1 spec is older than current standards.
• HAISSKY Running Armband – biggest strength: A phone pocket that fits screens up to 6.9", plus multiple zippered and hidden pockets for earbuds, keys, cards, and cash.
• HAISSKY Running Armband – biggest trade-off: It carries and protects your gear, but it produces no sound itself — you still need a separate pair of headphones.
• Who each is for: BEARTWO is for the person who wants wireless sound and clear calls during exercise. HAISSKY is for the runner who already has earbuds and just wants their phone and valuables locked down.
The BEARTWO Bluetooth Headphones are a neckband-style headset built around an active lifestyle. Instead of two independent buds that can slip out and roll under a treadmill, you drape a soft silicone band around your neck and pull out the retractable earbuds to whatever length you like — the wire extends up to about 28 cm and retracts when you're done. That single design choice solves the two most annoying problems with workout earbuds: dangling cables and lost buds.
The functional package is genuinely workout-oriented. The ear tips come in three gel sizes (small, medium, large) so you can get a secure in-ear fit, and the whole thing is described as sweatproof and lightweight. The controls sit on the outside of the neckband, so you can reach them without fumbling. A built-in mic with CVC noise cancellation handles calls, and there's a detail I find genuinely clever: the headset vibrates when a call comes in, so you won't miss it even in a noisy gym.
Buy it if you want one device that handles music, calls, and workouts without wires tangling. Skip it if your real problem is where to put your phone, keys, and cards — this headset doesn't store anything, and if you need the latest Bluetooth spec, the older 4.1 reference is worth noting.
HAISSKY Running Armband: Who It's For
The HAISSKY Running Armband is a carry-and-protect accessory, not an audio product. Its job is to strap your phone to your arm and keep your small valuables from falling out mid-stride. The phone pocket fits screens up to 6.9", which covers a wide range of current and recent devices — the compatibility list spans iPhone 17, 16, 15, 14, 13, 12, 11, and X families, plus Samsung Galaxy S25 and S24 series and several Sony Xperia models.
What makes it more than a basic sleeve is the pocket system. There's a zippered slot for earbuds, a car key, or other small items, and a built-in hidden pocket for credit cards, cash, or a key. That means you can run without a bulky waist pack. The screen window uses a clear TPU film so you can still use touch, password unlock, and gesture unlock, and it has three holes cut for charging and for routing a headphone cable.
The materials are chosen for sweat and weather. It's made from lightweight fabric and TPU, described as water-resistant, sweatproof, and washable, so light rain and splashes aren't a problem. The strap uses triple magic stickers and fits arms from about 10.5" to 15.8" (26.7–40.5 cm), and silicone particles on the back help stop it sliding during movement. Reflective strips wrap around the screen window for nighttime visibility.
Buy it if you already own earbuds and want a secure, reflective, water-resistant way to carry your phone and essentials. Skip it if you need sound — this armband is silent, and you'll still need a separate audio device.
Side-by-Side: Which Should You Choose?
• Best for carrying your phone → HAISSKY Running Armband. It fits screens up to 6.9", something the headset can't do at all.
• Best for battery life → BEARTWO Headphones. 16 hours of music and 18 hours of talk time is the only battery figure on the table.
• Best for keeping keys and cards safe → HAISSKY Running Armband. The zippered and hidden pockets are built for exactly that.
• Best for nighttime running safety → HAISSKY Running Armband. The reflective strips around the screen window are designed for low-light visibility.
• Best for cable-free workouts → BEARTWO Headphones. Retractable earbuds and a neckband mean no dangling wires.
• Best for sweat and rain protection of your phone → HAISSKY Running Armband. Its water-resistant, sweatproof, washable fabric and TPU cover your device.
• Best if you want one purchase to solve everything → neither alone. These are complementary: the armband holds the phone, the headset plays the audio.
If I had to pick just one, I'd buy the BEARTWO Headphones. In my opinion, it does more for the average exerciser because it delivers music, calls, and a vibration alert in a single sweatproof, retractable design, and the long battery life means fewer charging interruptions. The HAISSKY armband is excellent at what it does, but it's a supporting accessory — it only makes sense once you already have earbuds to pair with it. If you're building a running setup from scratch and want sound first, start with BEARTWO. If you already own headphones and just need to secure your phone and keys, the HAISSKY is the smarter pick.
FAQ
No. It's a phone and small-item holder only — there's a zippered pocket designed for storing earbuds, not a built-in audio device. You supply your own headphones separately.
The phone pocket is designed to fit screens up to 6.9", and the compatibility list explicitly includes iPhone 17/16/15/14/13/12/11 families and Samsung Galaxy S25 and S24 series, so large modern phones should fit.
BEARTWO lists 16 hours of music time and 18 hours of talk time, with a full charge taking about 3.5 hours via the included Micro USB cable. For the current price on either product, check the button on this page.
