The FEUR FU-IE700 is a single channel UHF wireless in-ear monitor system operating from 560 to 593 MHz across 100 selectable channels, with 48 kHz sampling, under 3 ms latency, a 30 Hz to 20 kHz response and IE-9 dual driver earphones included. It gives one performer a clean personal mix at 150 feet of coverage without a wedge on the floor.
Under 3 ms of latency, so what you hear is what you just played.
Latency is the number that separates a usable in-ear system from an unusable one. Above roughly 5 ms a singer starts hearing themselves late and pushes, and a drummer starts fighting the click. The FU-IE700 runs under 3 ms at a 48 kHz sampling rate and a 204.8 Kbps transmission rate, which keeps the monitor feed locked to the performance instead of trailing it.
Audio performance follows: dynamic range better than 90 dB, signal to noise better than 96 dB and total harmonic distortion under 0.1 percent across a 30 Hz to 20 kHz response. The 100 selectable UHF channels and unique ID addressing keep the system out of the way of other wireless in the building.
The included IE-9 earphones run a dual neodymium driver design with separate bass and tweeter elements, 16 ohm impedance and up to 25 dB of passive noise isolation. That isolation figure is what lets a performer monitor at a safe level, because they are blocking stage volume rather than trying to overcome it.
At a Glance
| Product Type | UHF Wireless In-Ear Monitor System |
| Configuration | Single bodypack receiver system |
| Frequency Range | 560 to 593 MHz |
| Channels | 100 selectable UHF channels |
| Sampling Rate | 48 kHz |
| Transmission Rate | 204.8 Kbps |
| Latency | Under 3 ms |
| Frequency Response | 30 Hz to 20 kHz |
How Much Latency Does the FU-IE700 Have?
Under 3 milliseconds. That is the specification that matters most in an in-ear system, because anything a performer can perceive as delay makes them push, drag or fight the click.
Who Is the FU-IE700 For?
One performer who needs a personal mix. A lead vocalist, a worship leader, a drummer working to a click, a bass player, or a presenter who needs program audio in their ear. It is also the honest starting point for a band moving off wedges one player at a time.
What Comes in the Box?
An IEM receiver unit, a bodypack transmitter, an FU-IE9 earphone set, soft rubber ear tips in small, medium and large, a 12V DC power adapter and the user manual. Call 844-687-4208 if you want it confirmed for your specific order.
How Far Does It Transmit?
Rated coverage is 150 feet, about 45.7 meters. That is measured with reasonable line of sight. Structural steel, concrete and heavy competing RF all reduce it in practice.
Can I Add More Receivers to One Transmitter?
In-ear transmitters broadcast one mix that any receiver on that frequency can pick up, so additional receivers can share a mix. Call us at 844-687-4208 and we will confirm the right receiver for your system before you add one.
Where Is the FU-IE700 Used?
FEUR lists these as the professional applications for this model:
- Studio Recording Sessions

Why FEUR?
FEUR was founded in Germany by a team of engineers and sound specialists who set out to make professional audio equipment that performs at a high level and stays within reach of the people who actually use it every week. Where most of the industry aims either at high-end studio work or at the bottom of the market, FEUR builds for the working middle: independent artists, houses of worship, schools, mobile operators and installed systems that need gear to show up and work every week.
Frequently Asked Questions
Is this a genuine FEUR product?
Yes. Victory is a veteran owned dealer in Miami and units ship new in original packaging.
Does the FU-IE700 come with a warranty?
Yes. It carries the FEUR manufacturer warranty against defects in materials and workmanship. Keep your invoice and call us at 844-687-4208 if you ever need service.
Are the earphones included?
Yes. A set of IE-9 Professional earphones ships with the system, using a dual neodymium driver design at 16 ohms with up to 25 dB of isolation.
Can I use my own earphones?
Yes, in most cases. The receiver drives standard earphones, though impedance and sensitivity will change the level you get. Call us at 844-687-4208 before you commit to a specific pair.
What frequency range does it operate on?
560 to 593 MHz, across 100 selectable channels. Confirm that this band is legal for your country before ordering internationally.
What batteries does the receiver take?
Two AAA cells. The transmitter runs from a 12V 1A DC supply.
Who should use in-ear monitor systems?
Live performers (vocalists, musicians, speakers) who need a personal monitor mix fed directly to their ears, eliminating dependence on stage wedge monitors and reducing overall stage volume.
How many performers can the FU-IE8.4 serve simultaneously?
The FU-IE8.4 quad-channel system supports up to four independent body-pack receivers simultaneously, each receiving its own dedicated mix from the transmitter.
What is the effective RF range of these systems?
Both models offer 150 ft (45.72 m) coverage — sufficient for most stage and arena applications — with under 3 ms audio transmission delay.
How does the FU-IE9 earphone achieve noise isolation?
The IEM uses advanced passive noise-isolation design with multi-size ear tips that form a physical seal in the ear canal, reducing ambient sound by up to 25 dB.
