Short answer: the M-Audio BX4 BT. It ranks #85 of 105 powered bookshelf speakers by sound quality, rated 3.3/5, at $218. The JBL One Series 104-BT ranks #99, rated 2.8/5, at $198, $20 cheaper, which does not close the gap in sound quality.
The M-Audio BX4 BT is the better-sounding option. A 4.5” Kevlar woofer and 1” silk tweeter per side with Bluetooth, RCA, 1/4” TRS and a front aux input, based on the M-Audio BX4 D3. Watch for: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers.
What the JBL One Series 104-BT does well: The JBL One Series 104 with Bluetooth 5.0 added: the same 4.5” coaxial woofer and 3/4” tweeter, 30W per speaker and RCA, 1/8” and balanced 1/4” inputs, so it works as a compact desktop system with or without a cable. Watch for: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers.
Buy the M-Audio BX4 BT. It is rated higher for sound quality, and the $20 you would save on the JBL One Series 104-BT does not close the gap.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: M-Audio BX4 BT 3.0 to 3.6; JBL One Series 104-BT 2.6 to 3.0). Treat this verdict as provisional.

Same family: the M-Audio BX4 D3 (smaller bookshelf, ranked higher, rated 3.4/5), the M-Audio BX5 D3 (larger bookshelf, ranked higher, rated 3.9/5) and the M-Audio BX8 D3 (larger bookshelf, rated 4/5).
Pros: A 4.5” Kevlar woofer and 1” silk tweeter per side with Bluetooth, RCA, 1/4” TRS and a front aux input, based on the M-Audio BX4 D3.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers. Rated only to 69Hz, so bass is light without a subwoofer, and its 25W per side amplifiers are modest.

Older model: the JBL One Series 104 (ranked higher, rated 2.8/5). See every JBL One Series 104 generation.
Pros: The JBL One Series 104 with Bluetooth 5.0 added: the same 4.5” coaxial woofer and 3/4” tweeter, 30W per speaker and RCA, 1/8” and balanced 1/4” inputs, so it works as a compact desktop system with or without a cable.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers. Bass rolls off at 88Hz (-3dB), so it sounds thin without a subwoofer, and output is modest for anything beyond a desk.
