If you want to turn any wired TV, stereo or old-school audio source into a dual-headphone Bluetooth setup, choose SOOMFON 5.3; if you need a standalone music player with its own storage and a huge battery, choose Aiandcc 64GB.
These two devices share a Bluetooth version number and almost nothing else. One is an audio plumbing tool that sits next to your TV. The other is a pocket-sized jukebox you carry with you. Comparing them is really a question of what you want to do, so let's get concrete about it.
• SOOMFON 5.3's biggest strength: it converts Optical, AUX and RCA input into a Bluetooth 5.3 signal, and it can drive two headphones or speakers at once with a stable range rated at 10–30 meters in open space.
• SOOMFON 5.3's biggest trade-off: it has no battery — it runs on DC/USB-C power — and it has no microphone, so karaoke, instruments and voice calls are off the table. It also can't pair with Alexa/Echo-style smart devices or anything needing a PIN.
• Aiandcc 64GB's biggest strength: 64GB of built-in storage (expandable to 128GB via TF card) plus a 410mAh battery rated at up to 56 hours of music playback at medium volume — a genuinely all-day, all-week device.
• Aiandcc 64GB's biggest trade-off: its Bluetooth only talks to headphones and speakers. It cannot connect to a TV, phone or computer, so it can't be your streaming hub.
• Who each is for: SOOMFON 5.3 is for the person with a wired TV or hi-fi who wants private listening for two; Aiandcc 64GB is for the runner, commuter or offline-music lover who wants their own library in their pocket.
Think of the SOOMFON 5.3 as a translator. Your TV, PC or stereo speaks Optical, AUX or RCA; your Bluetooth headphones speak Bluetooth. This little blue ABS box sits in the middle and handles the conversation. The headline trick is dual connection: two Bluetooth headsets or speakers can be linked at the same time, which is the difference between "one person watches with earbuds while the other sleeps" and "both of you watch together at full volume without waking the house."
The range claim is worth noting because it's unusually generous: 10–30 meters without obstacles, 10–20 meters with them. In practice that means you can pair up, walk to the kitchen, make dinner and still hear the dialogue. The 1.8-inch LCD shows you what's happening — pairing status, mode, volume — which sounds trivial until you've used a transmitter with nothing but a blinking LED and no idea what it's doing. There are physical volume buttons too, which matters for earbuds like AirPods that don't have their own controls.
Setup is where you need to pay attention. If you're using the optical connection, the TV's audio output format must be set to PCM, not Dolby or bitstream — that's the single most common reason people think a transmitter "doesn't work." The package includes an optical cable, a 3.5mm audio cable, a 3.5mm-to-RCA cable and a USB-C power cable, so you're covered for the usual scenarios out of the box, and SOOMFON backs it with a 2-year warranty plus lifetime technical support.
Who should buy it: anyone with a non-Bluetooth TV, desktop, MP3 player or older stereo who wants wireless headphone audio, especially couples or households where two people listen at once. Who should skip it: anyone wanting a portable player, a microphone for calls or karaoke, a hearing-aid transmitter, or Alexa/Echo integration. It's also not the tool for you if you want independent volume per listener — the two outputs share one volume control.
The Aiandcc 64GB is a different animal entirely: a self-contained music player. The 64GB of internal storage holds thousands of tracks, and if that's somehow not enough, a TF card slot takes you up to 128GB more (card sold separately). No subscription, no streaming, no phone — just your files, your folders, your playlists.
The battery is the real story. A 410mAh cell with a 3-hour Type-C charge is rated for up to 56 hours of continuous playback at medium volume in headphone mode, dropping to roughly 15 hours if you use the built-in speaker. That's a device you charge on Sunday and forget about for a week. The metal alloy shell and 2.4-inch color screen give it a sturdier, more modern feel than the plastic players this category is known for, and at 80.7 grams with a 4.25" × 1.95" × 0.37" body it disappears into a pocket or armband.
Who should buy it: runners, gym-goers, commuters, students and anyone who wants their own music library offline with enormous battery life — it even ships with a pair of test earphones and a Type-C cable. Who should skip it: anyone hoping to use it as a Bluetooth transmitter for a TV, phone or computer. The Bluetooth here is receive-only for headphones and speakers, so it can't be the bridge device that the SOOMFON is.
Side-by-Side: Which Should You Choose?
• Best for TV and home stereo audio → SOOMFON 5.3. Optical, AUX and RCA inputs are exactly what a TV or receiver needs.
• Best for two listeners at once → SOOMFON 5.3. Dual headphone connection is its defining feature; the Aiandcc has no equivalent.
• Best for battery life → Aiandcc 64GB. Up to 56 hours of headphone playback versus a device that needs constant USB-C power.
• Best for portability → Aiandcc 64GB. 80.7 grams with its own screen and storage; the SOOMFON is a stationary box.
• Best for storage capacity → Aiandcc 64GB. 64GB built in, expandable to 128GB via TF card.
• Best for long-range wireless freedom at home → SOOMFON 5.3. Rated 10–30 meters in open space, so you can roam the house.
• Best for runners and gym use → Aiandcc 64GB. Metal shell, lock key, breakpoint replay, 28-language interface.
• Best for voice recording, FM radio and e-books → Aiandcc 64GB. The SOOMFON has none of these and no microphone at all.
If I had to pick one knowing nothing else about you, I'd pick based on your setup, not your taste. If your problem is "my TV only outputs wired audio and I want wireless headphones," the SOOMFON 5.3 solves it directly and does something the Aiandcc physically cannot do. If your problem is "I want my own music, offline, for a week per charge," the Aiandcc 64GB is the more rewarding device. In my opinion the SOOMFON is the more specialized purchase — buy it because you have a specific audio-routing job for it, and it'll do that job well. Before either one, check the current price on Amazon, since that's the variable most likely to tip a close call.
FAQ
No. Its Bluetooth only supports headphones and Bluetooth speakers, and the manufacturer explicitly notes it doesn't connect to TVs, phones or computers. For TV audio, you want the SOOMFON 5.3.
Yes to both — it supports dual headphone connection, and the built-in volume control exists specifically for earbuds like AirPods that lack their own buttons. Just remember the two outputs share one volume level.
The Aiandcc 64GB, clearly. 64GB internal plus up to 128GB via TF card, and up to 56 hours of playback at medium volume. The SOOMFON is a powered transmitter, so battery life isn't part of its design at all.
