If you want total freedom from charging, a bombproof metal body and a wired connection you never have to think about, choose Bolanle P2; if you need to move around a stage untethered with digital wireless audio and a battery that tells you when it's running low, choose Retekess TA101.
These two boxes solve the same problem — getting a personal mix into your ears on stage — from opposite directions. One is a battery-powered wired amplifier you clip to your belt. The other is a full 2.4 GHz wireless transmitter-and-receiver system. That single design difference decides almost everything else.
• Bolanle P2 — biggest strength: wired reliability with XLR and 1/4" TRS inputs plus true stereo/mono switching, all in a metal-chassis belt-clip amp that runs on two AAA batteries.
• Bolanle P2 — biggest trade-off: it's a wired in-ear monitor amplifier, so you still run a cable from the console to your belt — there's no wireless freedom here.
• Retekess TA101 — biggest strength: a complete wireless IEM system with 2.4 GHz transmission, under 5 ms latency, 24-bit/48 kHz audio, 8 channels and up to 98 ft of range.
• Retekess TA101 — biggest trade-off: it's a rechargeable system with a roughly 5-hour runtime per charge, so long days mean planning around a 2.5-hour top-up.
• Pick Bolanle P2 if you're a drummer, keyboardist or bassist who plugs straight into the console and wants zero charging anxiety.
• Pick Retekess TA101 if you're a singer or band member who needs to roam a small-to-medium stage, church platform or rehearsal room without a tether.
The P2 is a specialist tool, and it's honest about that. It's a portable in-ear monitor amplifier with a solid-state design, 5 watts of output and a single output channel that feeds your in-ears. You connect it to your rig using either an XLR balanced input or a 1/4" TRS input — and crucially, you don't need adapters to do it. If your mixer, audio interface or PA has a spare XLR or TRS out, the P2 plugs straight in. That's the whole point.
The feature I'd point a drummer to first is the stereo/mono switch. In stereo you get full width in both ears. Flip to mono and you can run single-ear monitoring — genuinely useful when you need one ear open for the room, the click, or the rest of the band. It's a small switch that changes how the box fits real stage situations, not just spec-sheet situations. There's also a line out for chaining to a mixer, which makes it flexible in a rehearsal setup where you're sharing a feed.
Who should skip it? Anyone who genuinely needs to walk the stage. The P2 is wired, full stop. If your performance involves moving between risers, working a crowd, or sharing a stage where cables are a trip hazard, this isn't the tool. It's also not for you if you want an all-in-one system with earphones included — the P2 is the amplifier, and your in-ears are your own.
Retekess TA101: Who It's For
The TA101 is the opposite philosophy: cut the cable entirely. It's a complete wireless in-ear monitor system built around 2.4 GHz transmission, and the numbers matter here. Audio latency is under 5 ms, which is the figure that keeps a wireless IEM usable for live performance — enough delay and your timing starts fighting you. Sampling runs at 24-bit/48 kHz, so the monitoring path is designed to sound clean and natural rather than compressed and gritty.
Range is up to 98 feet (about 30 metres), which comfortably covers a small-to-medium stage, a church platform or a rehearsal room. In stereo mode you can place different elements across the stereo image using the mixer, so the mix has a sense of space in your ears; push a button and you're in mono. The kit ships as one transmitter and one receiver, with the earphones, a USB-C charging cable, an XLR-to-6.35 mm adapter and cable, plus a storage bag and box. That's a plug-in-and-go package.
The parts that matter for multi-person setups are the 8 selectable channels and the one-to-many / many-to-many support with independent mixing and a one-touch mute. In a room already crowded with wireless gear — multiple bands, a busy church tech desk, a studio with Wi-Fi everywhere — being able to hop channels to dodge interference is the difference between a working night and a noisy one. Retekess even flags the usual culprits: keep the transmitter and receiver close and away from routers, phones and other 2.4 GHz devices, and switch channels if things get ugly.
The trade-off is power and materials. Both the transmitter and receiver carry 1000 mAh batteries rated for up to 5 hours of continuous use, with low-battery warnings, and a full charge takes about 2.5 hours. Five hours covers most gigs and services, but a long festival day or a double-header means you're managing charge. The enclosure is ABS rather than metal, so treat it like the electronics it is. Retekess backs it with a two-year warranty and a 30-day return window.
Side-by-Side: Which Should You Choose?
• Best for charging-free reliability → Bolanle P2. Two AAA cells, swapped in seconds, no charge cycle to plan around.
• Best for stage freedom → Retekess TA101. Up to 98 ft of wireless range with no cable from the console to your belt.
• Best for studio and rehearsal work → Bolanle P2. XLR and 1/4" TRS inputs, no adapters, and a line out for feeding a mixer.
• Best for singers and front-of-stage performers → Retekess TA101. The wireless link is the entire reason this system exists.
• Best for multi-person bands → Retekess TA101. One-to-many and many-to-many connections with independent mixing, a one-touch mute, and 8 channels to dodge interference.
• Best for one-ear monitoring → Bolanle P2. The stereo/mono switch is explicitly aimed at drummers who want an ear free for the room.
• Best for durability on the road → Bolanle P2. An all-metal chassis and belt clip versus an ABS enclosure.
• Best for clean, low-latency wireless audio → Retekess TA101. Under 5 ms latency and 24-bit/48 kHz sampling.
If I were buying for myself as a gigging drummer or keyboardist who plugs into a console and stays put, I'd buy the Bolanle P2. In my opinion, the metal build, the XLR/TRS inputs, the mono switch and the AAA-battery design make it the more dependable tool for a fixed position — nothing to charge, nothing to pair, nothing to drop out. I'd pick the Retekess TA101 instead the moment movement matters: if I'm a singer working the front of a stage, or part of a multi-person band that needs independent mixes and channel flexibility, the wireless system is the one that actually changes how I perform. Decide which of those two musicians you are, and the choice makes itself.
For a drummer who stays behind the kit, the Bolanle P2's stereo/mono switch and AAA-battery operation fit the job well, and single-ear mono mode is exactly what many drummers want. The TA101 is the better pick if you need to move around the kit area or share a stage wirelessly.
Its stated latency is under 5 ms, which is designed to keep monitoring effectively real-time for stage work. That's the number to compare against any other wireless IEM system you're considering.
Both the transmitter and receiver use 1000 mAh batteries rated for up to 5 hours of continuous use, with low-battery notices. A full charge takes about 2.5 hours, so plan a top-up between long sessions.
Yes — it offers both XLR balanced and 1/4" TRS inputs, so it connects directly to mixing consoles, audio interfaces and PA systems. If price is the deciding factor for you, check the current price on Amazon using the button on this page.
