If you want a single all-day headset for calls and meetings, choose Lenovo 115; if you need to feed several listeners from one source with independent control, choose PROAR 4-Channel. That's the whole decision in one line. These two products share almost nothing except a 3.5-adjacent world of audio — one is a headset you wear, the other is a box that splits a signal to many headphones. Below I break down exactly who each one fits, based only on what the spec sheets actually say.
• Lenovo 115 — biggest strength: A complete, featherlight 140 g wired headset with both USB-A and USB-C connectivity, an in-line control box, and hybrid noise cancellation. It's a personal listening-and-talking device.
• Lenovo 115 — biggest trade-off: It's built for one wearer only. There's no multi-listener output, and its controls live on a remote box rather than the earcup.
• PROAR 4-Channel — biggest strength: Four independent channels driving up to 8 headphones at once, each with its own volume knob, mute, and MONO/STEREO switching. It's a shared-monitoring hub.
• PROAR 4-Channel — biggest trade-off: It makes no sound on its own — you need headphones and a source, and it's a desktop/studio box, not something you wear.
• Pick Lenovo 115 if you're one person who wants a light, comfortable headset for calls, meetings, and light gaming.
• Pick PROAR 4-Channel if you're a studio, band, podcast crew, or family that needs several people hearing the same source with their own volume control.
The Lenovo 115 is a wired over-ear stereo headset with a microphone, and its whole identity is "one ergonomic unit." It connects over USB-A or USB-C, so it works with laptops, desktops, and anything with those ports — no dongle juggling needed since a USB-A to USB-C adapter is part of the package. That single-cable, plug-in-and-go approach is what makes it a sane default for remote work, online meetings, and casual gaming.
Who should buy it? The person who lives in back-to-back calls and wants a light, wired, no-fuss headset with both USB standards covered. Who should skip it? Anyone who needs to send one audio source to several people at once, or who wants a desktop monitoring hub. The 115 is a personal device — it does that one job well and stops there. If price matters to you, check the current price on Amazon rather than guessing from the spec sheet.
PROAR 4-Channel: Who It's For
The PROAR 4-Channel is a headphone amplifier, and it solves a completely different problem: getting one signal to many ears, each with their own control. It offers four independent channels that together drive up to 8 headphones through 4 x 6.35 mm and 4 x 3.5 mm stereo TRS output jacks. That means a band, a podcast panel, a gaming group, or just a family sharing one source can each plug in and set their own level.
The input side is genuinely flexible: 1/4" (6.35 mm), 1/8" (3.5 mm), and RCA inputs let you connect computers, phones, digital players, mixers, instruments, and sound systems. Three of those inputs carry one-click mute buttons for precise signal control. Each channel has its own rotary volume knob, and there's independent MONO/STEREO switching — mono folds left and right into a single output for certain monitoring or recording situations, while stereo keeps channel separation for a wider soundstage.
Two details stand out in the spec sheet. First, the build: a compact metal body that the design notes say helps reduce electromagnetic interference for cleaner sound, plus an independent power switch so you can turn it off without unplugging. Second, the 7-color RGB breathing lights integrated along each knob, which change automatically at random — a cosmetic touch aimed at streaming desks and dim studios. PROAR positions itself around condenser microphones and affordable audio gear, and this amp fits that budget-minded, multi-user mindset.
Side-by-Side: Which Should You Choose?
• Best for solo calls and meetings → Lenovo 115. Built-in mic, in-line mute/volume, and both USB standards make it a one-person communication tool.
• Best for multi-listener monitoring → PROAR 4-Channel. Four channels, up to 8 headphone outputs — no contest here.
• Best for all-day comfort → Lenovo 115. At 140 g with memory-foam over-ear cups, it's designed for long wear; the PROAR is a stationary box.
• Best for independent volume control across users → PROAR 4-Channel. Each channel has its own rotary knob plus mute buttons.
• Best for portability → Lenovo 115. A 0.27 kg headset you wear versus a metal desktop amplifier you place.
• Best for source flexibility → PROAR 4-Channel. 6.35 mm, 3.5 mm, and RCA inputs cover mixers, instruments, and sound systems.
• Best for mono/stereo monitoring flexibility → PROAR 4-Channel. Per-channel MONO/STEREO switching is something the 115 simply doesn't offer.
• Best for a single, tidy cable setup → Lenovo 115. USB-A or USB-C straight into your machine, nothing else to configure.
My Verdict
They do different things, so "better" depends on the task. The Lenovo 115 is a personal headset with a mic and dual USB; the PROAR 4-Channel is a multi-listener amplifier. For solo calls, the 115 wins; for shared monitoring, the PROAR wins.
No — the spec sheet describes it as a headphone amplifier with 8 outputs, not a headset. It has no built-in microphone and produces no audio on its own. You'd still need a headset like the Lenovo 115 or other headphones plugged into it.
Up to 8 headphones, using its 4 x 6.35 mm and 4 x 3.5 mm stereo TRS output jacks across four independent channels, each with its own volume knob.
The Lenovo 115, based on its design: 140 g with memory-foam over-ear earcups built for all-day wear. The PROAR is a desktop metal box you don't wear, so comfort isn't a factor in the same way.
