Questions about this item

Will the Lightning connector or 3.5 mm jack need replacement after extended daily use?

The unit draws power directly from the iPhone or iPad over the Lightning port and has no internal battery, so only the cable and jack contacts experience wear.

What is the first limitation reached during long listening sessions at high volume?

Maximum output is constrained by the host device's Lightning port power delivery, so sustained loud playback may hit that current limit before the amplifier itself clips.
