Codec support is where the gap between these two earbuds becomes stark. The Soundpeats Air 5 Pro arrives with an impressive stack: LDAC, aptX Lossless, aptX Adaptive, aptX, and AAC — covering virtually every high-resolution and high-efficiency audio transmission standard available today. LDAC streams at up to three times the bitrate of standard Bluetooth audio, aptX Lossless can deliver CD-quality audio over a wireless link, and aptX Adaptive dynamically adjusts bitrate for a balance of quality and stability. For audiophiles or anyone streaming from a high-resolution source, this suite is genuinely meaningful. The JBL Tune Beam 2, by contrast, lists none of these codecs, meaning it falls back on the standard SBC codec — adequate for casual listening but leaving significant audio quality on the table for discerning ears.
The Air 5 Pro also runs on Bluetooth 5.4 versus the Tune Beam 2's Bluetooth 5.3, and adds Bluetooth LE Audio support — a forward-looking protocol designed for improved efficiency and multi-stream audio. Both share the same 10 m maximum range and USB-C charging. The Tune Beam 2 does offer fast pairing, which the Air 5 Pro lacks, making initial device setup marginally quicker — but this is a minor convenience against the Air 5 Pro's connectivity depth.
The Soundpeats Air 5 Pro wins this category and it is not particularly close. Its combination of high-resolution codec support, a newer Bluetooth version, and LE Audio compatibility gives it a substantial technological edge for users who care about audio fidelity and future-proofing their wireless connection.
