Stage monitoring
Shure PSM300 vs Sennheiser ew IEM G4
Quick answer
Buy the PSM300 at $989.00 for a first or second in-ear channel, because the package includes earphones and MixMode lets the musician blend two sources themselves. Choose the ew IEM G4 at $1,249.00 when in-ear channels compete with your microphones for spectrum.

Check price on AmazonBoth are professional wireless in-ear systems and both will serve a church for a decade. The PSM300 at $989.00 is the better first purchase because it is cheaper and the listed package includes the earphones that actually make in-ears work. The ew IEM G4 at $1,249.00 is the better system once you are running enough channels that finding clear frequencies has become the hard part.
Compare the packages carefully rather than the headline prices, because earphones are a large share of the cost of any in-ear channel and different bundles include different things. A system bought without proper isolating earphones does not reduce stage volume at all, which is the whole reason to buy one. Plan the channel count against your wireless microphones on the wireless channel calculator.

Where the price difference goes
The gap is about $260 at list. Three things account for most of it, and only one of them matters below about four in-ear channels.
The ew IEM G4 tunes across 46 MHz with up to 20 compatible channels against a narrower PSM300 range, which is the entire argument once in-ear channels start competing with wireless microphones for spectrum.
| Property | Shure PSM300 | Sennheiser ew IEM G4 | Matters when |
|---|---|---|---|
| Tuning range | Set by band, narrower | 46 MHz | Six or more wireless channels total |
| Compatible channels | Fewer per band | Up to 20 published | A large band on in-ears |
| Earphones | SE215 included in this package | Check the bundle before comparing | Always, they are a third of the cost |
| Limiter | In the system | In the bodypack | Hearing protection, use it either way |
| Musician control | MixMode blends the two channels | Balance control on the pack | Musicians who adjust their own mix |
| Rack format | Half rack transmitter | One rack unit | A rack with eight transmitters in it |
| Battery | Up to 8 hours | AA cells in the bodypack | Long conference days |
| Price as listed | $989.00 | $1,249.00 | The first channel |
The Shure package listed here includes SE215 earphones. Check what any in-ear bundle contains before comparing two prices, because earphones are a large part of the cost and some systems ship without them. The Galaxy AS-1400 at $449.99 is the clearest example: a cheap UHF system that includes no earphones at all.
Choose the PSM300 for the first two or three in-ear channels
Most churches start in-ear monitoring with one musician, usually the worship leader, and the PSM300 is the cheapest complete way to do that properly. The listed package includes SE215 earphones at $119.00 of value, and their roughly 37 dB of isolation is the specification that makes the platform quieter. A system without that isolation is just headphones.
MixMode is the feature churches underuse. It lets the musician blend the two transmitted channels with their own knob, so the operator can send a full band mix on one and that musician's own voice on the other, and the musician sets the balance themselves. That removes the most common in-ear complaint, which is that somebody needs more of themselves and the operator is busy.
Growing it is cheap. The Twin Pack at $1,539.00 puts two musicians on one shared mix, and a P3RA bodypack at $499.00 adds a listener to an existing transmitter. Only buy another P3T transmitter at $399.00 when somebody genuinely needs a different mix rather than a different volume.
Choose the ew IEM G4 when spectrum has become the constraint
In-ear transmitters and wireless microphones share the same UHF band, and in-ear systems are worse neighbours because a transmitter runs continuously at higher power. A church with six wireless microphones and four in-ear channels is coordinating ten frequencies in a band that keeps shrinking, and that is exactly where a 46 MHz tuning range and up to 20 compatible channels stops being a specification and starts being the reason the system works.
The rack format matters at the same point. A single rack unit per transmitter keeps a dense system tidy and serviceable where half-rack boxes and a pile of power supplies do not. Size it with the rack space calculator and lay it out with the rack planning guide. The G4 Twin at $1,649.00 feeds two bodypacks from one transmitter and one frequency, which is the efficient way to add a pair of musicians to an already crowded plan.
The limiter in the bodypack is worth calling out as a safety feature rather than a convenience. It caps what can reach the musician's ears when a channel spikes, which is the failure that does real damage with a driver sitting in the ear canal.

Frequently asked questions
Do in-ear systems use the same frequencies as our wireless microphones?
Yes, and that is the planning problem most churches miss. Both live in the UHF band, and an in-ear transmitter runs continuously at higher power than a microphone transmitter does. Coordinate every transmitter in the building as one plan, and count in-ear channels against your total when you run the wireless channel calculator.
Are the included earphones good enough to start with?
The SE215 is genuinely good enough and is the standard first pair of real in-ear monitors, with roughly 37 dB of isolation. The cheaper SE112 bundle works but isolates less, which matters because isolation is the reason the platform gets quieter. What does not work is a musician using consumer earbuds with no seal.
Can musicians use their own earphones?
Yes, any wired earphone with a standard connector will work with either bodypack, and many musicians prefer their own moulded pairs. Set one rule: they must isolate. An open or loosely fitting earphone defeats the purpose, and it leads to the musician pushing the level up to hear over the room, which is the dangerous failure mode.
How many in-ear channels does a church band actually need?
Count distinct mixes rather than musicians. The drummer and the worship leader nearly always need their own, and backing vocalists frequently share one happily. A five piece band commonly needs three genuinely different mixes, which is why twin packs and shared mixes are the efficient way to build this rather than one transmitter per person.
Is a cheap in-ear system a false economy?
It is if it ships without earphones, because the earphones are what deliver the isolation you are buying the system for. A budget transmitter and bodypack paired with proper isolating earphones is a reasonable way to add channels. A budget system paired with whatever earbuds a musician had in their bag is not.
