  • Sports Team1 Piece
  • Private listening without disturbing a partner with under-pillow close-range audio
  • Stream from phone or play offline via microSD card with three playback modes

Private Listening for Shared Spaces

The Upgrade F50 is a slim audio component designed to sit under a pillow for close-range playback. It keeps podcasts, audiobooks and music near the listener instead of filling the room, making it a considerate choice for shared beds or late-night routines. Bluetooth, a dedicated sleep mode and a TF/microSD slot provide three ways to start listening without a screen.

Suited to Solo Bedtime Listening

This speaker suits anyone who wants personal audio in bed without disturbing a partner or roommate. The ultra-thin profile stays comfortable under a pillow and the auto-off timer handles shut-off after you fall asleep. Buyers who need room-filling sound, louder volume for daytime use or a battery that lasts beyond the rated 10 hours should look at larger alternatives.

Battery Life Defines the Session

The built-in cell delivers up to 10 hours of playback on a full charge, which covers a typical night and a short wind-down period. If your routine regularly runs longer than that without a chance to recharge, this model will not last the full stretch.

Questions about this item

Does the F50 get warm or make any noise after running all night?

The ultra-thin design has no moving parts and stays cool during the 10-hour battery life, so it remains silent and comfortable under your pillow.

What do I need to already have to use the TF card mode on the F50?

You need a TF or microSD card loaded with audio files; the card is not included and the speaker starts playing automatically once inserted.

Will the F50 Bluetooth connection work with an older phone that only supports earlier Bluetooth versions?

Bluetooth mode streams from any phone that supports standard Bluetooth audio, letting you play music, podcasts or audiobooks wirelessly.
