Does anyone know if there's a headphone practice amp with Bluetooth capability? I want something I can put into my bass gig bag. The Ashdown Tone Pocket would be perfect for the lack of BT. I know it has a line-in, but increasingly phones just don't have that capability, and even if it did I prefer the convenience of not plugging it in. As an aside it would make for a nice headphone adapter for a phone for general use when not practising.
There are practice amps with the functionality, but nothing that I would consider portable enough to sling into a gig-bag.
Is there a product I'm just not finding with my Google-fu?
