How we chose
We did not test these products in person and we never claim to. Picks are researched from manufacturer specification sheets and operator manuals, FCC rules where spectrum is involved, published standards, warranty terms, and the recurring themes in verified owner reviews. Every pick is matched to a real room size, seat count or input list rather than to a price bracket, and it is placed in the tier where its capability actually belongs. Where a product is wrong for most churches we say so on the page.

Frequently asked questions
How much does the Sennheiser ew IEM G4-A1 cost?
It was listed at $1,249.00 when this page was last compiled. Pro audio and video pricing moves frequently and promotional pricing is common, so treat that as a planning figure and confirm the current price before a committee votes on a budget.
Is the Sennheiser ew IEM G4-A1 right for our church?
Bands large enough that in-ear channels compete with the microphones for spectrum. Beyond that, the honest test is whether its numbers match your room rather than whether it is a good product in the abstract. Work out what your room actually needs first, then check this model against that answer.
Where do these specifications come from?
The manufacturer’s published figures, taken from the product listing and data sheet. We do not test products in person and we never claim to, so nothing here is a measured result. Where a specification is not published by the manufacturer it is omitted rather than estimated.
Researched, not professional advice. This page is compiled from published manufacturer specifications, operator manuals, FCC rules, published standards and owner-review consensus, not hands-on testing. Sound system design, rigging loudspeakers overhead, and any electrical work are jobs for a qualified professional: have flown loudspeakers and their attachment points signed off by a structural engineer or a certified rigger, and have all wiring done by a licensed electrician to your local code. Wireless microphone rules change, so confirm the current FCC position before buying. As an Amazon Associate we earn from qualifying purchases.
