How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired personal monitor rig that mixes your mic and your monitor feed into two headphone outputs, choose ROLLS PM50s; if you need a cable-free wireless in-ear monitor system for two performers at once, choose GOKKO GAF-10. One is a compact problem-solver for a fixed position. The other is a freedom machine for a moving one.
• ROLLS PM50s biggest strength: It mixes a stereo monitor feed with a microphone and passes both to two separate headphone outputs, with independent level control for each. That is a genuinely rare combination in a box this small.
• ROLLS PM50s biggest trade-off: It is wired and needs the included external power supply. You are tethered to the rig, and there is no wireless range at all.
• GOKKO GAF-10 biggest strength: One transmitter plus two receivers means two performers monitor the same source wirelessly, up to 30 meters outdoors, with 24-bit/48kHz digital audio and stereo, left, right and mute modes.
• GOKKO GAF-10 biggest trade-off: Earphones are not included, so budget for your own in-ears. Battery life is also split — 24 hours on the transmitter but only about 6 hours per receiver.
• Who the PM50s is for: A vocalist, drummer or presenter who stands in one spot and needs their own mic blended into their monitor mix.
• Who the GAF-10 is for: Singers, guitarists, keyboard players and church bands who want to move around a stage or rehearsal room without a monitor cable dragging behind them.
The PM50s is best understood as a personal mixer, not a headphone amplifier in the ordinary sense. It takes a stereo monitor feed through a 1/4" TRS input, blends that with a microphone signal, and sends the combined mix out to a pair of headphone outputs. Two XLR jacks and a microphone pass-through jack handle the mic side, so the mic signal can continue on its way to the rest of the system while you listen to it yourself. That pass-through detail matters more than it sounds. It means you can insert the PM50s into an existing mic line without breaking the chain.
You get a monitor level control and a microphone level control, set separately. In practice that is the whole point of the device. If the band gets loud, you nudge your monitor feed up. If your own voice is getting buried, you nudge the mic up. You are not asking a sound engineer to redo your mix mid-set.
The footprint is deliberately tiny. That is a design decision with real consequences: it fits on a cramped stage riser, a podium, a drum throne or a cluttered desk where a full-size mixer would not. It runs on an included external power supply rather than batteries, so it is a plug-in-and-leave-it device. The headphone connection is a 6.35 mm jack, and the bundle includes a 10-foot Hosa extension cable with molded connectors and a rugged outer jacket, which is useful because it lets you put the box down and still reach your ears.
Buy it if you perform or present from a fixed position and want your own mic mixed into your own headphones, with two outputs so a second person can share the same mix. Skip it if you need to walk the stage, or if you want anything wireless. There is no wireless technology here at all — the connectivity is wired, and the noise control is listed as none, so treat it as a clean signal path rather than a noise-cancelling device.
The GAF-10 is a different animal entirely. This is a 2.4GHz wireless in-ear monitor system built around one transmitter and two receivers. That "two receivers" part is the headline. Two performers can monitor the same audio source simultaneously, which makes it a natural fit for a duo, a pair of vocalists, a guitarist and a keyboard player, or a worship team where two people need the same reference.
Audio is delivered digitally at 24-bit/48kHz over 2.4GHz. The system is designed for low-noise, low-latency feedback, which is exactly what you want when you are listening to yourself in real time — latency is the enemy of anyone trying to sing or play in time. Range is quoted at up to 30 meters, roughly 98 feet, outdoors. GOKKO is upfront that you should keep a clear signal path and avoid large metal objects, walls, scaffolding and strong wireless interference, which is honest and worth taking seriously in a venue with a lot of steel and RF traffic.
Power is handled by USB-C, and the transmitter is rated for up to 24 hours of battery life while each receiver is rated for up to 6 hours. That asymmetry is worth planning around: the transmitter will outlast your gig, but the receivers are the limiting factor, so a charging routine before rehearsal or service matters. A charging case is included, which makes that routine easier.
Each receiver supports stereo, left-channel, right-channel and mute modes, with independent volume adjustment so each performer sets their own level. The receivers are compact clip-ons designed to attach to a belt, pocket, guitar strap or stand. One important caveat: earphones are not included. You supply your own in-ears, so factor that into your setup.
Buy it if you want to move freely, you regularly work with a second performer, or you are tired of long monitor cables snaking across a stage. Skip it if you need a mic blended into your monitor mix — that is not what this system does — or if you want a single self-contained box with nothing else to buy.
• Best for mixing your own mic into your monitors → ROLLS PM50s. The mic pass-through and separate mic level control are unique to it here.
• Best for wireless freedom on stage → GOKKO GAF-10. 2.4GHz transmission and up to 30 meters of range with no cable.
• Best for two performers sharing one source → GOKKO GAF-10. One transmitter plus two receivers, each with independent volume.
• Best for a fixed position with a cramped footprint → ROLLS PM50s. Small, powered, and designed to sit where space is tight.
• Best for a self-contained bundle → ROLLS PM50s. It ships with the power supply and a 10-foot headphone extension cable.
• Best for long sessions without battery anxiety → ROLLS PM50s. It runs from an external power supply rather than a battery.
• Best for digital audio spec → GOKKO GAF-10. 24-bit/48kHz over 2.4GHz.
• Best for belt-and-pocket convenience → GOKKO GAF-10. Clip-on receivers with stereo, left, right and mute modes.
• Watch out for → GOKKO GAF-10 buyers must supply their own earphones, and each receiver runs about 6 hours per charge.
In my opinion, the right pick comes down to one question: do you move, or do you stand still? If you stand at a mic and want that mic blended into your own headphones with independent control, I would buy the ROLLS PM50s. It solves a specific problem cleanly, and the included cable and power supply mean it works out of the box. If you roam a stage, play in a duo, or want to kill the monitor cable for good, I would buy the GOKKO GAF-10 and budget for a decent pair of in-ears to go with it. Neither is a compromise pick — they simply answer different questions. Check the current price on Amazon using the button on this page before you commit.
what is studio monitor headphones
Studio monitor headphones are designed to reproduce audio accurately rather than flatter it, so you hear what is actually in the mix. In this comparison, the ROLLS PM50s is a monitor amplifier that feeds headphones, while the GOKKO GAF-10 is a wireless in-ear monitor system — note that it does not include earphones.
why do djs wear headphones
DJs wear headphones to hear the next track before the audience does and to cue it against what is already playing. A monitor feed like the ROLLS PM50s, which blends a stereo monitor input with a microphone and outputs to two headphone jacks, fits that cueing role in a fixed setup.
why djs need headphones
Cueing, beatmatching and hearing yourself over a loud room all require a private listening path the crowd cannot hear. The GOKKO GAF-10 takes that idea wireless: 2.4GHz transmission, 24-bit/48kHz audio, and stereo, left, right and mute modes per receiver.
why djs wear headphones
Because the main speakers are pointed at the crowd, not at them. If you need to move while you listen, the GAF-10's two receivers and up to 30-meter range suit that; if you stay at the desk and need a mic mixed in, the PM50s is the better fit.
