How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to turn any wired TV, stereo or PC into a two-headphone wireless setup, choose SOOMFON 5.3; if you need headphones you can actually wear while swimming, running or cycling, choose FEICO Bone Conduction Headphones.
• SOOMFON 5.3 biggest strength: it is a Bluetooth 5.3 transmitter/receiver/splitter that sends audio from non-Bluetooth gear — TV, PC, MP3 player — to two Bluetooth headphones or speakers at once, with Optical, 3.5 mm AUX and RCA inputs, an LCD status screen and a rated range of 10–30 m.
• SOOMFON 5.3 biggest trade-off: it has no microphone, cannot pair with PIN-protected devices, and volume is not independently adjustable for the two connected devices.
• FEICO Bone Conduction Headphones biggest strength: open-ear bone conduction plus a built-in 32 GB MP3 player with IP68 waterproofing, so you can listen without a phone — including underwater in MP3 mode.
• FEICO Bone Conduction Headphones biggest trade-off: Bluetooth only reaches about 10 m, there is no noise control, and Bluetooth audio does not work underwater, so you must switch modes before submerging.
• Who each is for: SOOMFON 5.3 for the household that wants shared, silent TV listening or wireless speakers; FEICO for the athlete or swimmer who wants music on the move without blocking their ears.
SOOMFON 5.3 is not a pair of headphones. It's a small ABS box — model BT17, roughly 3.31" long with a 1.8-inch LCD — that sits between your audio source and your Bluetooth headphones or speakers. Its job is to solve a specific annoyance: your TV, stereo or PC has no Bluetooth, and you'd rather not run a long cable across the room or blast the sound at everyone else.
The headline feature is dual connection. It pairs with two Bluetooth headphones or speakers simultaneously, so two people can watch the same movie at their own volume without disturbing anyone else. After the first pairing, both devices reconnect automatically, which is the kind of detail that matters when you're doing this every night. The range is genuinely generous here — SOOMFON rates it at 10–20 m with obstacles and 10–30 m in open space, so you can walk to the kitchen or fold laundry and keep listening.
Connectivity is where this thing earns its keep. Optical, 3.5 mm AUX and RCA are all supported on both the input and output side, which covers TVs, PCs, MP3 players and older stereo gear. The LCD screen tells you what mode you're in and what's connected, and there are built-in volume buttons — useful for headphones like AirPods that don't have their own controls. You also get the cables in the box: AUX-to-RCA, 3.5 mm audio, optical and USB-C power, plus a two-year warranty.
Who should skip it? Anyone expecting a microphone. SOOMFON is explicit that this unit has none, so it's wrong for karaoke, musical instruments or calls. It also won't work as a transmitter for Alexa, Echo Dot or hearing aids, won't pair with devices that demand a PIN code, and can't set separate volumes for its two connections. If you use optical, remember to set your TV's audio output to PCM.
FEICO Bone Conduction Headphones attack a different problem entirely. These are open-ear sports headphones — model 9000S-PRO — built around a bone conduction driver with a 32 ohm impedance and a 20 Hz–20,000 Hz frequency range. Nothing goes inside your ear canal, so ambient sound stays audible while you listen. For runners, cyclists and drivers in traffic, that's the whole point.
The standout feature is the built-in 32 GB MP3 player. It handles MP3, WAV, FLAC and APE, so you can load your library onto the headphones and leave your phone at home. That matters most in the pool: the IP68 rating covers swimming, snorkeling and kayaking, but Bluetooth doesn't transmit underwater, so you switch to MP3 mode before you submerge. If you swim laps, this dual-mode design is the reason to look here.
Battery is a claimed 10 hours of playtime from about a one-hour charge, topped up via a magnetic 4-pin charging connection. Bluetooth 5.3 handles the wireless side with a stated range of roughly 10 m — fine for a treadmill, a bike or a phone in an armband, but not a whole-house solution. There's an integrated microphone for calls and media/volume/call controls on the headset itself. It weighs 0.27 kg and comes with a cable, headband and manual.
Where does FEICO fall short? There's no noise control at all — that's inherent to open-ear design, and it cuts both ways. Bass response from a bone conduction driver is not going to satisfy someone chasing thumping low end, and because sound travels through bone rather than air, loud environments can wash out quieter passages. The 10 m Bluetooth range is modest, and the included warranty is listed at 30 days, which is short compared with what you'd want on a pool-and-sweat device.
• Best for shared TV listening → SOOMFON 5.3. Two headphones at once, automatic reconnection, and a range that reaches across the house.
• Best for swimming → FEICO Bone Conduction Headphones. IP68 plus the 32 GB MP3 mode is the only way to get audio underwater between these two.
• Best for running, cycling or driving → FEICO. Open-ear design keeps traffic audible, and there's a mic for calls.
• Best for battery longevity away from a socket → FEICO. 10 hours per charge versus SOOMFON, which needs USB-C power while it works.
• Best for connecting old gear → SOOMFON 5.3. Optical, AUX and RCA in and out, which is far broader than any pair of headphones can offer.
• Best for long-range freedom around the home → SOOMFON 5.3. Rated 10–30 m depending on obstacles, against roughly 10 m for FEICO.
• Best for calls → FEICO. SOOMFON has no microphone and is not intended for that use.
• Best for people who hate things in their ears → FEICO. Bone conduction leaves the ear canal completely open.
These two barely compete — they solve different problems, so the honest answer is to buy the one that matches your actual frustration. If your TV, stereo or PC is wired and you want two people listening wirelessly without waking the house, I'd buy the SOOMFON 5.3; its dual connection, 10–30 m range and Optical/AUX/RCA flexibility make it the more capable hub, and the two-year warranty backs it up. If your priority is music while swimming, running or cycling, I'd buy the FEICO Bone Conduction Headphones instead — IP68 plus that 32 GB MP3 mode is something SOOMFON simply cannot do. In my opinion, the SOOMFON is the smarter buy for a household; the FEICO is the smarter buy for one active person. Check the current price on Amazon before deciding, since that's the one variable that could tip a close call.
No. It's a Bluetooth transmitter, receiver and splitter that sends audio from non-Bluetooth devices like a TV, PC or stereo to Bluetooth headphones or speakers — it doesn't play audio on its own.
Yes, within limits. The IP68 rating covers swimming, snorkeling and kayaking, but Bluetooth doesn't work underwater, so you must switch to the built-in 32 GB MP3 mode before submerging.
SOOMFON 5.3, clearly. It's rated at 10–20 m with obstacles and 10–30 m in open space, while FEICO lists roughly 10 m.
Only the FEICO. It has an integrated microphone and call controls. SOOMFON 5.3 has no microphone and is explicitly not intended for calls, karaoke or instruments.
