Greadio Portable Bluetooth CD Player with FM Transmitter

The Greadio Portable Bluetooth CD Player is a rechargeable, Bluetooth-enabled personal CD player that plays CDs/MP3s, streams wirelessly, and connects to car stereos via FM or AUX.

Bring physical media into modern life: this compact player reads CD, CD-R, CD-RW and MP3 files, doubles as a USB music player, and supports Bluetooth transmit and receive modes. A 2000mAh battery offers long runtimes, while anti-skip buffering, a backlit display, and USB-C charging make it convenient for travel, commuting, or at-home listening. The unit includes built-in stereo speakers, a 3.5mm headphone jack, and both an FM transmitter and AUX output to work with most car radios and external speakers.

How does this player connect to my car stereo?

The Greadio player provides three simple ways to deliver audio to your car: wired through a 3.5mm AUX cable, wirelessly using the built-in FM transmitter (tune your car radio to 87.5–108MHz), or by playing audio to Bluetooth headphones or speakers. Note the Bluetooth function does not pair as a car Bluetooth module.

• AUX cable output for direct connection and low-latency sound
• Adjustable FM transmitter frequency to avoid interference
• Bluetooth transmitter mode streams CD audio to wireless speakers or headphones
• USB playback option for MP3 files from a flash drive

Will it skip while I move around or drive on rough roads?

Greadio uses enhanced anti-skip buffering to keep playback steady whether you're walking, jogging, or on bumpy roads. The player provides a longer buffer for MP3s and a solid buffer for standard CDs so short shocks won't interrupt music.

• 120-second anti-skip for MP3 files
• 60-second anti-skip for standard audio CDs
• Physical clamshell with secure disc tray reduces vibration
• Compact, lightweight design minimizes movement inside bags or cup holders

How long does the battery last and how do I charge it?

The built-in 2000mAh rechargeable battery supplies over nine hours of continuous playback, even with Bluetooth active, making it reliable for day trips and extended listening sessions. Charging is via USB-C and typically completes in about four hours using a standard power bank or wall adapter.

• 2000mAh battery for long runtime (9+ hours typical)
• USB-C fast charging; compatible with common chargers and power banks
• LED/backlit display shows battery and playback status
• Low-battery indicator and efficient power management

What playback features and controls does it offer?

Controls are straightforward: play/pause, skip, repeat/program play, and a sleep timer, plus Bluetooth pairing and FM frequency selection. The backlit LCD makes menu navigation easy in low light, and you can use wired or wireless headphones for private listening.

• Programmable track sequence and repeat modes
• Sleep timer and backlit LCD for nighttime use
• Built-in stereo speakers and 3.5mm headphone jack for private listening
• Detachable lanyard included for comfortable portability

Who is this for? The Greadio Portable Bluetooth CD Player suits anyone who still treasures physical media but wants modern flexibility: commuters who prefer CDs in older cars, nostalgic listeners who collect discs, travelers who need a rechargeable player, and users who want a lightweight device that doubles as a Bluetooth streamer and USB MP3 player. It’s a practical bridge between retro collections and wireless convenience, designed for everyday use and backed by a 12-month warranty and lifetime support.
