If you want a single pair of Bluetooth over-ear headphones that folds flat, shuts itself off automatically, and works with any device you already own, choose VBJZO Advent Audiovox MTGHP2CA; if you need a set of four infrared headphones built specifically for in-car rear entertainment systems so the whole family can watch different screens at once, choose Key Audio RP Accessories IR-601B.
• VBJZO Advent Audiovox MTGHP2CA — biggest strength: Bluetooth 4 wireless with a 10-meter range, so it pairs with phones, tablets and TVs without any extra transmitter box.
• VBJZO Advent Audiovox MTGHP2CA — biggest trade-off: No headphone jack and no noise control, so it is wireless-only and won't plug into a wired seat-back system.
• Key Audio RP Accessories IR-601B — biggest strength: A four-pack of dual-channel infrared headphones with a 3.5 mm jack and an included aux cable, built for two-monitor car setups.
• Key Audio RP Accessories IR-601B — biggest trade-off: Infrared only works line-of-sight with an IR transmitter (not included), and each headset needs two AAA batteries you supply.
• Who each pick is for: One person who wants a versatile everyday Bluetooth headphone → VBJZO Advent Audiovox MTGHP2CA. A family with a factory or aftermarket car DVD/TV system → Key Audio RP Accessories IR-601B.
The MTGHP2CA is a straightforward over-ear wireless headphone. It runs Bluetooth 4 with a rated range of about 10 meters, which is the practical, no-drama spec you want: you can leave your phone on the kitchen counter and keep listening while you move around a room, or leave a tablet on the seat tray and stay untethered in a seat. The 20 Hz – 20,000 Hz frequency range covers the full audible spectrum, and the dynamic driver is the standard, well-understood design for this class of headphone.
What I like about the design intent here is the fold-flat build. Over-ear headphones are the bulky option, and a fold-flat hinge is exactly the feature that makes them livable — they collapse down for a bag, a glovebox or a drawer instead of taking up a hard case's worth of space. The auto shut-off is the other quietly useful spec. Wireless headphones left powered on are the classic way to drain a battery you forgot about; auto shut-off removes that whole failure mode. Batteries are included, so there's no scavenger hunt on day one.
Who should buy it: someone who wants one flexible, packable Bluetooth headphone for music, podcasts, streaming and general home or commute use, and who is fine charging and pairing rather than plugging in. Who should skip it: anyone who needs a wired fallback, active noise cancellation, or a headset that talks to a car's infrared entertainment system — this one simply doesn't do those jobs.
Key Audio RP Accessories IR-601B: Who It's For
The IR-601B is a different animal entirely, and it's important to understand that before you buy. This is a set of four infrared wireless headphones sold as a replacement for rear entertainment systems in vehicles. It is not a Bluetooth product. It's not a general-purpose headphone. It is a purpose-built accessory for a car TV or DVD player that already has an infrared transmitter — and if you don't have that transmitter, these headphones have nothing to listen to over the air.
Where it shines is exactly that use case. The dual-channel IR design means that when you have two monitors running two different programs, one passenger can tune to the first channel and another to the second. That's the whole point of the two-channel spec, and it's the feature that turns a long road trip from a negotiation into a quiet ride. The four-pack matches a family — kids in the back with their own headset and their own volume, parents up front hearing nothing but the road.
The fit-and-finish details are the ones a family actually cares about. The headband is adjustable to fit all head sizes, the ear pieces are soft-padded for longer wear, and each headset has its own volume control so nobody has to share a level. There's an auto shut-off after five minutes of inactivity to stretch battery life, and the whole thing folds completely inside itself for storage in a door pocket or console bin. Setup is essentially nil — no pairing, no programming, just power on. Note the power: two AAA batteries per headset, which are not included. The headphones also carry a 3.5 mm jack and ship with an aux cable, so you can use them wired with a tablet or phone when you're not in the car. Noise control is listed as sound isolation, which is exactly what an over-ear padded cup gives you — physical blocking, not active cancellation.
Who should buy it: anyone replacing or expanding the headphones for a vehicle's factory or aftermarket IR rear-seat entertainment system, especially with two screens and multiple passengers. Who should skip it: anyone without an IR transmitter in the car, anyone who wants Bluetooth, and anyone who only needs a single pair.
• Best for wireless freedom and everyday devices → VBJZO Advent Audiovox MTGHP2CA. Bluetooth 4 with a 10-meter range pairs with phones, tablets and Bluetooth-capable TVs; the IR-601B cannot do this.
• Best for in-car rear entertainment → Key Audio RP Accessories IR-601B. It is designed for car TV/DVD systems with an IR transmitter, and the four-pack covers the whole back seat.
• Best for two screens at once → Key Audio RP Accessories IR-601B. The dual-channel IR design lets two passengers watch two different programs on two monitors.
• Best for packing and travel → VBJZO Advent Audiovox MTGHP2CA. Fold-flat over-ear design plus a media remote and auto shut-off make it the easier one to toss in a bag. (The IR-601B also folds into itself, but it's tuned for vehicle use.)
• Best for wired fallback → Key Audio RP Accessories IR-601B. It has a 3.5 mm jack and an included aux cable; the MTGHP2CA is wireless-only with no jack.
• Best for a multi-person household → Key Audio RP Accessories IR-601B. You get four headsets in one set, each with its own volume control.
• Best for a single listener who wants one headphone for everything at home → VBJZO Advent Audiovox MTGHP2CA. Dynamic driver, full 20 Hz – 20,000 Hz range, and it just works over Bluetooth.
• Best if you don't want to buy batteries → VBJZO Advent Audiovox MTGHP2CA. Batteries are included; the IR-601B needs two AAA per headset, not included.
Both are good at very different jobs, so my recommendation depends entirely on your setup — and I'd rather you buy the right one than the "better" one. If you have a car with an infrared rear entertainment system and multiple passengers, I'd buy the Key Audio RP Accessories IR-601B: the dual-channel, four-headset design is purpose-built for exactly that, and nothing else here replaces it. If you don't have an IR transmitter in your vehicle, though, I'd buy the VBJZO Advent Audiovox MTGHP2CA instead — Bluetooth 4, a 10-meter range, fold-flat portability and auto shut-off make it the one that's useful every single day, not just on road trips. In my opinion, the MTGHP2CA is the safer pick for most people who just want one reliable wireless headphone. Check the current price on Amazon before you decide, since that's the one variable that can tip a close call.
It's Bluetooth 4 wireless, with a rated range of about 10 meters. That means it pairs with phones, tablets and other Bluetooth devices — it does not use infrared and won't talk to a car's IR system.
Yes, but only wired. It has a 3.5 mm jack and ships with an aux cable, so you can plug it into a tablet or phone that way. Over the air it's infrared only, so it needs an IR transmitter to work wirelessly.
The VBJZO Advent Audiovox MTGHP2CA includes batteries. The Key Audio RP Accessories IR-601B does not — each of the four headsets needs two AAA batteries for wireless use.
Yes. That's the point of its dual-channel IR design. With two monitors, one passenger can tune to the first channel and another to the second, so two people can watch two different programs at once. Each headset also has its own volume control.
Neither is designed for that. The MTGHP2CA lists no noise control, and the IR-601B only offers sound isolation from its padded ear cups. If active noise cancellation is your priority, look for a headphone that specifically lists it.
