A Must-Have for Musicians
The Fzone in-ear monitor has quickly become an essential part of my setup, and I couldn’t be happier with its performance. As a bassist, I use it connected to the output of a direct box to hear my instrument, and it has made a significant difference in my live performances and rehearsals. Sound Quality: The sound quality is outstanding for the price. The bass response is clear and precise, and I can hear every note with excellent clarity. The in-ear monitors do a great job of isolating the sound, allowing me to focus on my bass guitar without distraction from the surrounding noise. The mids and highs are also well-balanced, providing a full range of sound that ensures I never miss a detail during a performance. Comfort and Fit: The Fzone in-ear monitors come with multiple ear tip sizes, making it easy to find the perfect fit. They sit comfortably in my ears, even during long sessions, and the secure fit ensures they stay in place no matter how active I get while playing. I’ve worn them for hours at a time without discomfort, which is a big plus for long rehearsals or gigs. Ease of Use: Setting up the Fzone in-ear monitors with my direct box was a breeze. The connection is straightforward, and they work seamlessly with my gear. The cable is durable and long enough to provide flexibility during live performances, allowing me to move freely without any restrictions. Durability: These monitors are built to last. They feel sturdy and well-constructed, and I’ve had no issues with wear and tear despite regular use in rehearsals and live performances. The quality of the materials and build ensures that these in-ear monitors can withstand the rigors of being on stage. Value for Money: For the price, the Fzone in-ear monitor offers incredible value. They deliver excellent sound quality, comfort, and durability at a price point that’s hard to beat. If you’re a musician looking for an affordable in-ear monitor solution, this is a fantastic choice. Overall Impression: The Fzone in-ear monitor has made a noticeable improvement in my playing experience. It allows me to hear my bass guitar clearly and accurately, which is crucial for staying in time and tuning during performances. Whether you’re a bassist, guitarist, or any other musician, I highly recommend these in-ear monitors as a reliable and cost-effective solution.

Very pleasantly surprised in so many ways
Like many of you reading this review I'm thoroughly disappointed by the total sound output volume of my iPhone (and especially when used in combination with my bluetooth receiver I use connected to my favorite WIRED headset when hiking, biking, or working outdoors. Yes, I'm not only fully aware of the dangers of listening with headphones to loud volume music / podcasts, etc. But that's my freedom to decide. That said, and seeking more, I came across this marvelous mini amp / volume control (I'll call it the FZONE from here). Yes, it's just a hair bulkier than I prefer but the build quality is exceptional. So far after a month of heavy use clipped to my belt while cutting grass, leaf blower, power tools, etc. this thing not only works like a champ, it's astonishing how little battery power it draws. I've only been using the cheap non-alkaline "heavy duty" batteries I sometimes get for free as a bonus at Harbor Freight and they last days and days before losing charge. I especially love how the FZONE uses actual batteries instead of requiring plug-in. Great design choice. So my rig is I connect the mini bluetooth receiver output via a mini connecting cord to FZONE input and my wired headset stays connected via an adapter to the FZONE output. Thus, nothing needs to be connected to my phone so it can remain well protected in its case in a pocket or even elsewhere within line-of-sight. The bluetooth receiver acts as my play / pause / etc. controller (even answering calls!) where all the while I'm enjoying quick and easy volume control on my hip with this FZONE. So yeah. So far, so great. I'm finally hearing the audio detail I've been missing for a long time (even after the slightly diminished audio quality resulting from the bluetooth link along the way. A GREAT value IMHO.

FZONE IEM Amplifier - Nice features and a competitive price
The FZONE IEM amplifier is very similar to the Behringer P2. I actually have both, trying to decide which one to keep. The positives: sound quality is very good. Clarity is good if you have a quality set of IEMs. The volume gain is graduated to my liking, so when you turn the dial to make changes in volume the change is subtle -- no big jumps. This is handy for finding an in-ear volume that is "just right". The belt clip is very stiff - it takes some force to spread the clip. Trust me, you will not lose this device while playing. The batteries can be changed externally (nice!) via an opening on the side (unlike the P2, which requires the unit to be "disassembled" to access/change the batteries). The negative: the only negative I can find is the location of the MONO/STEREO switch. While it's convenient to have it external, having it near the volume knob has been problematic. (On the P2, you have to disassemble to move the switch). I like the switch being external, however more than once I have reached to adjust the volume and accidentally flipped the MONO/STEREO switch. Perhaps I will get used to it, I just don't know. But a recessed switch that requires a "pin" to switch seems better, or at least change the location so it's not adjacent to volume. Durability is not known yet. I play out live in all kinds of venues, so time will tell if it holds up to the rigors of frequent use in a working band loud setting.

Works well, battery compartment is nice, I like the mono/stereo switch
I had a similar model from a competitor. You had to open it to change the batteries. After opening it many times, the cover started getting caught on a PC board. Eventually, it caused damage and crackling. I expect this model's swing-open battery compartment to keep that damage from occurring. My previous one was only stereo, so when sending a single channel, I only got the sound in one earpiece. This model's mono/stereo switch means I can now hear the sound in both earpieces.

Sounds great.
Great product. It’s nice that the stereo/mono switch is on the outside.

Good, better than the other cheaper versions. Robust metal case, led when on is blue, feels goid quality. I use decent leads and IEMs and had good sound with plenty of volume

nach einem viertel Jahr war der Verstärker defekt, genauer gesagt der Schalter zur Umschaltung Stereo/Mono. wurde unbrauchbar und verschwand dann endgültig im Gehäuse, trotz wenig benutzt.

Aunque Behringer es pionero en este dispositivo, hay muchos otros similares que han tratado de copiar la funcionalidad y no lo logran al 100%, podría decir que este modelo le llega a un 99% y esto por lo bueno: 1. Las pilas se ponen por fuera 2. El clip tiene mejor resistencia y diseño 3. Mono/stereo está por fuera, no hay que desarmar 4. Tiene buen sonido y no satura LO MALO, 1. Es de plástico, se siente un poco frágil y 2. Si le subes a tope, literal sube a tope, la diferencia con Behringer es que el Behringer si tiene un limitador de volumen y jamás satura. Fuera de eso hasta ahorita no tengo queja, Con Behringer P2 llevaba 7 años antes de fallar ahora veremos cuánto dura este modelo.
