If you want a wireless neckband you can wear through sweaty runs and long commutes with your phone in your pocket, choose ASKUBSKU Neckband; if you need a pocketable FM radio with retro analog tuning and a built-in headphone amp, choose FiiO RR11. These two barely overlap. One is a Bluetooth audio wearable. The other is a standalone radio receiver with a Hi-Res Audio badge. The rest of this comparison walks through who each one actually fits.
• ASKUBSKU Neckband — biggest strength: A flexible memory-silicone neckband with Bluetooth 5.0 wireless audio, a 10mm dynamic driver, and on-wire push-button controls for volume, calls and track skipping.
• ASKUBSKU Neckband — biggest trade-off: It is sweatproof but explicitly not waterproof — the brand says to keep it out of rain, swimming and bathing — and it runs Bluetooth 5.0 rather than a newer generation.
• FiiO RR11 — biggest strength: A lighter-sized, aluminum-bodied FM receiver (83.2mm x 39.4mm x 13mm) using the Silicon Labs Si4831 chip, with analog PVR-style tuning, a PCB signal-gain antenna, and a bundled DAC cable that turns it into a small headphone amp.
• FiiO RR11 — biggest trade-off: It is a radio first. Wireless streaming and app-based control aren't part of its design — audio comes through wired earbuds or headphones, and its FM band starts at 64MHz, not the typical 87.5MHz.
• Pick ASKUBSKU Neckband if you mainly want wireless music, calls and workouts tied to your phone.
• Pick FiiO RR11 if you want a self-contained FM tuner for over-the-air radio, campus broadcasts and wired listening.
The ASKUBSKU Neckband is a straightforward Bluetooth neckband headphone. The spec sheet keeps things simple: Bluetooth 5.0 wireless, an in-ear design with rounded tips that insert into the ear canal, a 10mm dynamic driver covering 20Hz–20,000Hz, and an in-line push-button control for call and volume control. There's no jack — it's wireless only — and the enclosure is plastic in white.
What it does best is convenience-on-the-go. A neckband sits around your neck instead of inside a charging case, so you can pop the buds in and out during a run without fiddling with a case. The memory-silicone band is designed to bend and spring back into shape rather than deform, and it's skin-friendly for longer wear. The brand ships three eartip sizes (S/M/L), which matters more than people expect for in-ear comfort and seal. Pairing is a simple press-and-hold, and the headset auto-reconnects when you turn it back on — handy if you swap between a phone, a tablet and a laptop.
Who should buy it: runners, walkers, gym-goers and commuters who want wireless audio with physical buttons they can find by feel. The wide compatibility list covers a huge range of current Samsung Galaxy, Google Pixel and iPhone models, so you're unlikely to get stuck on pairing. Who should skip it: anyone who needs to use headphones in the rain, in the shower or while swimming — the sheet is explicit that these are sweatproof, not waterproof. If you want active noise cancellation, look elsewhere; the noise control here is sound isolation from the in-ear seal, not ANC. And if you're chasing the newest Bluetooth codecs, note this is Bluetooth 5.0.
The FiiO RR11 is a different category of device entirely — a portable HiFi FM stereo radio receiver, not a wireless headphone. Its body is about the size of a mainstream lighter (83.2mm x 39.4mm x 13mm) and made of aluminum, with an aluminum-alloy knob that mimics analog PVR tuning. That wheel gives you the tactile, immediate feedback that digital tuners can't replicate, and it's the heart of the retro-modern appeal here.
Inside, FiiO uses the Silicon Labs Si4831 professional FM chip, which the brand credits with stronger station search and more stable reception. The band runs 64–108MHz, so beyond standard FM stations you can also reach campus FM broadcasts. Reception is helped by two design choices: the RR11 can use your headphones as an antenna, and it also has a high-performance PCB signal-gain antenna built in. For a device this small, that's a thoughtful combination.
Who should buy it: radio listeners who want over-the-air FM without a phone, people who like tactile analog tuning, and anyone curious about the amp/DAC-cable trick for wired listening. Who should skip it: if your main goal is wireless streaming from a phone, this isn't that device. It's wired output, battery-powered, and built around radio reception first.
Side-by-Side: Which Should You Choose?
• Best for wireless freedom → ASKUBSKU Neckband. Bluetooth 5.0, auto-reconnect, no cable to your phone.
• Best for over-the-air radio → FiiO RR11. FM 64–108MHz with the Si4831 chip, campus band included.
• Best for workouts and sweat → ASKUBSKU Neckband. Memory-silicone band, sweatproof build, three eartip sizes.
• Best for tactile, analog feel → FiiO RR11. The aluminum PVR-style tuning wheel is the whole point.
• Best for hands-on control while moving → ASKUBSKU Neckband. Push-button volume, call and track control on the wire.
• Best for wired listening upgrades → FiiO RR11. The bundled conversion cable turns it into a small headphone amp with DDB 3D effects.
• Best for size and portability → FiiO RR11. Lighter-sized, aluminum, slips into a pocket or bag.
• Best for phone-first everyday use → ASKUBSKU Neckband. Broad Samsung, Pixel and iPhone compatibility plus simple pairing.
In my opinion, most people searching these two names actually want wireless headphones, and for them the ASKUBSKU Neckband is the more useful pick — Bluetooth 5.0, in-line controls, a bend-resistant memory-silicone band and a sweatproof design fit daily running, walking and commuting. I'd choose the FiiO RR11 only if radio is the point: a pocketable aluminum FM receiver with analog tuning and a bundled amp cable is a genuinely different, more specialized tool. Decide which job you're buying for, and the choice stops being close.
No. The brand describes it as sweatproof but not waterproof, and specifically says not to use it in rain, swimming or bathing. Sweat during workouts is fine; getting it soaked is not.
No. The RR11's connectivity is auxiliary, and it's designed around wired earbuds or headphones, using them as an antenna for better FM reception. For wireless audio you'd want a Bluetooth device like the ASKUBSKU Neckband instead.
The ASKUBSKU Neckband, in my opinion — its neckband design, sweatproof build and secure in-ear fit suit movement. The FiiO RR11 is a pocket radio, better left in a bag or on a desk while you listen.
Value depends on the job you need done, so check the current price on Amazon for each and compare against the features that matter to you — wireless audio and controls versus FM reception and analog tuning. They solve different problems, so the "cheaper" one isn't automatically the better buy.
