How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a way to turn your existing wired in-ear monitors into true wireless earbuds, choose Fanmusic TRN BT20; if you need a self-contained portable CD player with its own speaker, rechargeable battery and Bluetooth output, choose SKYANS CD Player.
• Fanmusic TRN BT20 — biggest strength: It converts wired IEMs into a Bluetooth 5.3 true-wireless setup with 13 hours per charge and up to 50 hours with the included charging case.
• Fanmusic TRN BT20 — biggest trade-off: It is a module only. No earphones are included, so it is useless unless you already own 2-pin 0.78mm in-ear monitors.
• SKYANS CD Player — biggest strength: A complete, standalone disc player with a built-in 2000mAh rechargeable battery, built-in HiFi speaker, Bluetooth 5.3 transmitter and CD/AUX/USB playback.
• SKYANS CD Player — biggest trade-off: Its Bluetooth works as a transmitter only. It cannot receive Bluetooth audio, so it will not act as a speaker for your phone or tablet.
• Who each pick is for: Fanmusic TRN BT20 for IEM owners who want wireless freedom without buying new earphones; SKYANS CD Player for anyone who wants to play physical CDs at home, in the car or on the move.
The TRN BT20 Pro is best understood as an upgrade part, not a finished product. It is a pair of swappable Bluetooth earphone modules with 2-pin 0.78mm connectors that slot onto in-ear monitors you already own. Fanmusic and TRN built it around a simple idea: your IEMs probably sound good, so why replace them just to cut the cable? Snap the modules on and a wired set becomes a true-wireless set.
The spec sheet backs that up with Bluetooth 5.3 — faster transmission, lower power draw and stronger anti-interference than older versions — plus AAC and SBC support and a stated 15-metre wireless range. Battery life is the headline: 13 hours of playback per charge, extended to roughly 50 hours with the portable charging case, which recharges in about 150 minutes. A two-hour charge on the modules themselves gets you back to full. There is also a water- and sweat-resistant nanocoating, which matters if you wear IEMs while running or commuting in bad weather.
SKYANS CD Player: Who It's For
The SKYANS CD Player sits at the opposite end of the spectrum: it is the whole product in one box. It reads CD, CD-R, CD-RW, MP3 and WMA discs, and it does so without tethering you to a wall socket thanks to a built-in 2000mAh rechargeable battery. That is the core of its appeal — no hunting for AA batteries, no permanent charging cable. It is designed to travel, whether that means a car, a hotel room, a kitchen counter or a study desk.
Playback flexibility is where it earns its keep. It supports single-song loop, whole-disc loop and random playback, and you can switch between them as you like. Beyond discs, there is a USB flash drive player mode and a 3.5mm AUX output for external speakers or a car stereo. Bluetooth 5.3 is on board as a transmitter, so it can send audio to Bluetooth speakers or headphones. One clear limitation to note: it does not have Bluetooth receiver functionality, so it cannot pair with a phone or tablet as a playback source, and the AUX connection does not carry Bluetooth either.
It ships as a complete kit — the player itself, a USB-C charging cable, a set of wired earphones, a remote control and a manual — with a one-year warranty and a white plastic body that weighs next to nothing at 1.6 ounces. The included speaker means you can listen out of the box. Small, easy-to-press buttons handle track skipping, play/pause and mode cycling. One genuinely useful tip from the documentation: if the volume buttons stop responding, check the side switch — it may be in the "HOLD" position rather than "ON".
Who should buy it? People with a CD collection who want a simple, portable way to keep using it, plus parents and gift-givers looking for something tangible for a child or friend. Who should skip it? Anyone who has moved entirely to streaming, and anyone hoping to use it as a Bluetooth receiver for their phone. This is a disc player first and foremost.
• Best for turning existing earphones wireless → Fanmusic TRN BT20. It exists purely to make 2-pin 0.78mm IEMs wireless.
• Best for playing physical CDs → SKYANS CD Player. It reads CD, CD-R, CD-RW, MP3 and WMA discs and offers loop and random modes.
• Best for battery life per charge → Fanmusic TRN BT20. 13 hours per charge, up to about 50 hours with the charging case.
• Best for a rechargeable, battery-free experience → SKYANS CD Player. The 2000mAh built-in battery removes the need for AA cells.
• Best for hands-free listening at home → SKYANS CD Player. The built-in HiFi speaker means no extra gear required.
• Best for wireless output to a speaker or headphones → SKYANS CD Player. Bluetooth 5.3 works as a transmitter.
• Best for workouts and sweaty commutes → Fanmusic TRN BT20. The water- and sweat-resistant nanocoating is built for it; the SKYANS player is not described that way.
• Best for a complete, ready-to-use package → SKYANS CD Player. It includes earphones, a USB-C cable, a remote and a manual; the TRN BT20 includes no earphones at all.
In my opinion, these two products barely compete — they solve different problems, so the right buy depends entirely on what you already own. If you have a pair of 2-pin 0.78mm in-ear monitors gathering dust because of the cable, I would buy the Fanmusic TRN BT20. It is the cheaper-feeling upgrade in spirit: one purchase, and your existing IEMs go wireless with 13 hours of playback and a charging case that stretches that toward 50. If you have shelves of CDs and want to actually play them — at home, in the car, or anywhere with a 3.5mm input — I would buy the SKYANS CD Player. It is the complete product, and it works the moment you unbox it. Check the current price on Amazon for whichever one matches your setup before deciding.
No. It is a Bluetooth earphone module only, and headphones are not included. It fits 2-pin 0.78mm in-ear monitors that you already own. Without compatible IEMs, it has nothing to attach to.
No. Its Bluetooth 5.3 works as a transmitter only, sending audio to Bluetooth speakers or headphones. It has no Bluetooth receiver function, so it cannot pair with a phone or tablet as a source.
The Fanmusic TRN BT20 offers 13 hours of playback per charge, extendable to around 50 hours with its portable charging case, and takes about two hours to charge. The SKYANS CD Player uses a built-in 2000mAh rechargeable battery; runtime depends on volume and mode.
They are not directly comparable, so value depends on your needs. If you already own 2-pin 0.78mm IEMs, the TRN BT20 adds wireless freedom without new earphones. If you need a standalone CD player with a speaker and rechargeable battery, the SKYANS covers more ground in one purchase.
