Media Players and Handheld Devices

Physical media, digital files or streaming: what you already own

Start from the media you actually have. Tapes need a cassette player or a recorder-converter, discs need a portable CD or DVD player, and a digital music library suits an MP3 & Digital Music Players model with storage or a card slot. Reading calls for an e-reader with an e-ink screen, navigation for a GPS unit, and speech for a voice recorder. If you want old tapes and modern wireless listening together, look at Tape Players & Recorders with Bluetooth output.

Plugs and power: the connection must match what you already have

Headphone connections vary: a 3.5 mm plug is standard on portable gear, a 6.3 mm plug is common on studio headphones and amplifiers, and USB-C or Bluetooth takes over when there is no jack. Power varies too. Some devices have a built-in rechargeable battery charged over USB, others take AA or C cells, and older players need a mains adapter with the right voltage and plug polarity. The wearing-style words in listings help with comfort: circumaural means over-ear cups, supra-aural means on-ear pads, and binaural means a pair of earpieces.

Questions about Media Players and Handheld Devices

Can I use Bluetooth headphones with a CD or cassette player?

Only if the player has Bluetooth output. Otherwise plug a small Bluetooth transmitter into its 3.5 mm headphone jack, which sends the sound to your headphones wirelessly. Check that the transmitter battery lasts as long as your trip.

What is the difference between a 3.5 mm and a 6.3 mm plug?

Both carry stereo sound, but the 6.3 mm plug is the larger studio size and the 3.5 mm plug is the portable size. Small adapters convert between them, so you can use headphones on either kind of socket.

What do circumaural and supra-aural mean?

Circumaural headphones have cups that surround the ear, which suits long listening and blocks more noise. Supra-aural ones rest on the ear, so they are lighter and smaller but can feel tight after hours.
