Plays straight from a phone
A phone or laptop reaches full listening level. An amp is a choice, not a requirement.
| Needs, for 110 dB peaks | 0.42 V · 10 mW |
| Phone or laptop (≈0.70 V, 20 mW) | Enough |
| Dongle DAC/amp (≈2.0 V, 120 mW) | Enough |
Worked out from the stated 117.5 dB/V and 17.5 Ω — not a listening test.
