If you’ve got a great old stereo system or set of speakers but no built-in wireless, a Bluetooth to RCA receiver is the easiest way to modernize it. All of the products below take audio from your phone, tablet, or computer over Bluetooth and output through RCA (or AUX/optical) into your stereo. None of these units transmit RCA to Bluetooth. They’re all receivers only.

Let’s go through each one, what direction it works in, and why it might be a good choice.

Auris Blume HD

Direction: Bluetooth → RCA / Optical

This is one of the most premium adapters on the list. Auris built the Blume HD with audiophiles in mind, pairing Bluetooth 5.3 with high-end audio codecs like aptX HD, aptX Low Latency, and LDAC. The big feature here is the built-in 384kHz/32-bit DAC, which ensures that whatever music you stream sounds as close to lossless as possible.

Highlights:

• Streams from phone, tablet, or PC into stereo via RCA or optical
• Audiophile-grade DAC built-in
• Extra-long Bluetooth range (100+ ft)
• Compact, well-designed with cable management
• Buy on Amazon

Perfect if you want to turn your serious home stereo system into a wireless Hi-Fi rig without sacrificing audio quality.

BluDento B2 aptX HD, LDAC

Direction: Bluetooth → RCA / AUX / Optical / Coaxial

The BluDento B2 is the most flexible and high-end of the group. It supports aptX HD, LDAC, and AAC codecs, includes an ESS ES9018K2M DAC, and gives you analog RCA, AUX, plus digital coaxial and optical outputs. The external antenna also helps extend range well beyond standard receivers.

Best for audio enthusiasts who want both analog and digital output options and the absolute best sound from their Bluetooth connection.

Our Take

Every device here does one thing: Bluetooth audio in → RCA (or similar) out. None of these are transmitters, so if you’re looking to send RCA audio out to Bluetooth headphones, you’ll need a different type of device.

For pure quality, the Auris Blume HD and BluDento B2 stand out as premium choices for audiophiles. If you just need something affordable and practical, the Xingbaichen is the clear budget pick. The Rockford is as simple and reliable as it gets, while the Slash3 balances compactness and high-res audio nicely.

No matter which one you pick, each of these adapters can breathe new life into your classic stereo system by making it wireless without losing sound quality.
