Choose a cassette player if you already own tapes, listen mostly on wired headphones, and enjoy the format’s mechanical character, hiss included. Choose a CD player with a speaker if you want an album playing on a desk or bedside table, or you plan to burn your own discs. The music you will actually put in the player settles this more reliably than nostalgia for either format.
This guide compares the FiiO CP13 Transparent portable cassette player with the km5 Instant Disk Audio CP2, a CD player with a built-in speaker and Bluetooth output.
Why choose physical media at all
A physical album asks you to pick one record and let it play. There is no feed suggesting the next track, and the object itself, a cassette turning behind a clear lid or a disc framed by its sleeve, becomes part of listening. That experience is not, by itself, a reason to expect better sound than the streaming service you already use.
Start with what you will play
A box of family tapes or a CD collection in a cupboard is the strongest argument for the matching player. Otherwise, check whether the artists you follow release new music on cassette, CD, or neither, and how easily you can find second-hand copies locally.
CD has one practical advantage for building a collection: you can burn your own. km5 lists CD, CD-R, CD-RW, and MP3 discs for the CP2, though it also says it cannot guarantee playback of every disc, so test a burned CD-R before committing to a large batch. FiiO says it removed the recording and auto-reverse functions to simplify the CP13’s mechanism, so you cannot make tapes with it, and you will turn each cassette over by hand.
Alone on headphones, or in the room
The CP13 is built around personal listening. FiiO’s parameter sheet lists playback of cassette Types I to IV, a standard 3.5 mm headphone output, an 1,800 mAh battery rated for at least 13 hours, and USB-C charging. It has no speaker, so it needs wired headphones; the Nothing Headphone (a) is one option, since Nothing supports a 3.5 mm Aux-In connection.
The CP2 can be shared. km5 lists a built-in speaker, a 3.5 mm jack, and Bluetooth output to wireless headphones or speakers, with about 6 to 7 hours of battery on the speaker and 7 to 8 hours over Bluetooth. Its Bluetooth only sends audio: you cannot stream from your phone to its speaker. The speaker suits a desk or bedside table rather than a large room. In Spain, the CP2 ships from Amazon UK with import charges included, so confirm the delivery terms on the listing.
| Player | Plays | Output | What to check |
|---|---|---|---|
| FiiO CP13 Transparent | Stereo cassette, Types I to IV | 3.5 mm headphones only | Condition of your tapes; no recording or auto-reverse |
| km5 Instant Disk Audio CP2 | CD, CD-R, CD-RW, MP3 discs | Built-in speaker, 3.5 mm, Bluetooth out | Burned-disc compatibility; speaker size for your room |
Hiss, heads, and scratches
Tape is an analogue magnetic format, and FiiO is direct about the result: its CP13 page says the noise floor is significantly more audible than on a digital player. If background hiss during quiet passages would bother you, CD is the better fit. A cassette mechanism also has moving parts and a playback head in contact with the tape, so older tapes and the player itself will need some care over time. FiiO’s published specifications do not set out a service schedule, and this guide does not establish how long either mechanism lasts.
Discs ask for less routine attention, but scratches and dirt can still interrupt playback, so store them in their cases.
Frequently asked questions
Can the CP13 record cassettes?
No. FiiO removed recording and auto-reverse, so it plays tapes only and you turn them over by hand.
Can I stream from my phone to the CP2’s speaker?
No. km5 says its Bluetooth sends audio out to headphones or speakers but does not receive it.
Which is better for a first collection?
The format your existing music, local shops, and favourite artists already support. Browse the Tech collection for headphones to pair with either player.
