MP3 and iPod Accessories

Batteries, docks and cases are made for one exact player

Almost everything here is made for a particular player. Batteries are matched by model number and sometimes by connector, so confirm that your player is named in the listing. For iPods, check the generation and connector: older models used a wide 30-pin dock connector, and later iPod touch and nano models use Lightning, so a dock or cable for one will not fit the other. Cases and armbands are cut for a screen size and button layout, and a generic armband needs enough height and width for your player.

Armbands, FM transmitters and power adapters on the move

A sports armband should fit your arm, hold the player firmly and leave the controls reachable, ideally with a window for a touchscreen. An FM transmitter sends music from the player or a phone to a car radio over a free FM frequency, so choose one that lets you pick a quiet channel, and plug it into a power source with enough current. Power adapters must match voltage, polarity and plug size; a mismatched adapter can damage the player. A power bank with USB output charges many players away from a socket.

Questions about MP3 and iPod Accessories

How do I know which battery fits my music player?

Find the player's model number, usually printed on the back or inside the battery bay, and match it to the model list in the battery listing. Also compare voltage and the connector shape rather than relying on size alone.

What does an FM transmitter do?

It broadcasts a weak FM signal that a car radio can tune to, letting you play music from a player or phone through the speakers. Pick a frequency with no local station to avoid interference.

Do old iPod docks fit current iPods?

Usually not. Older docks use a 30-pin connector, while recent iPod touch and nano models use Lightning. Check the connector named in the listing against your player, and if you use an adapter, confirm that it carries audio and charging.
