• Avantree Add-on 2.4G — biggest strength: 2.4GHz RF wireless with roughly 30ms latency, which keeps voices and lips in sync, plus it joins an existing Avantree Duet, Quartet 5049 or Audiplex 2403s system where up to 100 headphones can run off one transmitter.
• Avantree Add-on 2.4G — biggest trade-off: It is an add-on headphone only. It is not meant to be bought on its own, and it needs one of those Avantree kits already in the house to work at all.
• We Are Rewind EQ-001 — biggest strength: Bluetooth 5.1 freedom with a 33-foot range, three swappable ear cushions in orange, yellow and black, and three EQ modes (Signature, Balanced, Bass Boost).
• We Are Rewind EQ-001 — biggest trade-off: Bluetooth audio latency sits around 40ms rather than the near-instant RF timing, and there is no wired fallback since the connection is Bluetooth only.
• Who each pick is for: Avantree for households already running a Duet/Quartet/Audiplex system that want another listener on the couch; We Are Rewind for one person who wants a stylish, portable daily headphone for a phone or a WE-001 cassette player.
The Avantree Add-on 2.4G, sold under the Duet-Extra name, is a very specific tool. It exists so that one more person — a partner, a visiting parent, a friend — can listen to the same TV, movie or music as everyone else in the room without disturbing anyone. The trick is the 2.4GHz RF link, which Avantree rates at roughly 30ms of latency. Compare that to ordinary Bluetooth, and the difference matters: dialogue lands where the mouth moves.
The sharing angle is the real headline. Up to 100 of these headphones can be connected to the transmitter of a Duet, Quartet 5049 or Audiplex 2403s kit, and adding more headphones does not introduce extra lip-sync delay for anyone already listening. Each pair has its own volume control, so a hard-of-hearing viewer can crank it up without touching anyone else's level. There is also a Clear Voice mode that digitally lifts on-screen dialogue, and an EQ adjustment for tuning the sound. Battery is claimed at 20 hours per charge with a 2-hour charge time.
Who should buy it: you already own an Avantree Duet, Quartet 5049 or Audiplex 2403s kit and want to add a listener. Who should skip it: anyone without one of those kits, since this is explicitly not a standalone purchase, and anyone hoping for noise cancelling — there is none here.
We Are Rewind EQ-001: Who It's For
The EQ-001 is the opposite kind of product: self-contained, portable and built to be worn out of the house. It pairs over Bluetooth 5.1 with a stated 33-foot range, which is plenty for a phone in a pocket or a laptop across the room. It also works with We Are Rewind's own WE-001 cassette player, which is a neat detail if you are already in that ecosystem — a modern wireless headphone for a retro tape deck.
Style is a genuine selling point. You get three interchangeable ear cushions in orange, yellow and black, so the look changes without buying anything else. The build is plastic with an oval over-ear shape, and it is light — around 0.1kg — with an adjustable headband and soft cushions for longer wear. The 40mm dynamic drivers run 32 ohms across 20Hz–20,000Hz, matching the Avantree on paper for frequency range.
Sound shaping is where it flexes: Signature, Balanced and Bass Boost modes let you push low end or flatten things out depending on the track. Controls are button-based rather than touch — a single-click "GO" button handles playback and calls, and a double-click on the mic function wakes Siri or Google Assistant. There is a built-in digital MEMS microphone for calls. Battery is 12 hours with a 2-hour charge, and it ships with a micro USB cable. Two-year warranty.
Who should buy it: someone who wants one pair of headphones for music, podcasts and calls on a phone, and who likes the retro look and swappable pads. Who should skip it: anyone who needs the tightest possible lip-sync for TV, or a wired backup — the EQ-001 is Bluetooth only, with no 3.5mm jack listed.
Side-by-Side: Which Should You Choose?
• Best for group listening → Avantree Add-on 2.4G. Up to 100 headphones on one transmitter, each with independent volume.
• Best for standalone everyday use → We Are Rewind EQ-001. It works on its own over Bluetooth, with no kit required.

• Best for headphone comfort over long sessions → Avantree Add-on 2.4G. Memory foam over-ear pads, rotatable cups and replaceable earpads.
In my opinion, these two barely compete — they solve different problems, so the "winner" depends entirely on what you already own. If you have an Avantree Duet, Quartet 5049 or Audiplex 2403s kit and you want another person on the couch hearing the TV in sync, I would buy the Avantree Add-on 2.4G without much hesitation. The ~30ms latency, 20-hour battery and per-headphone volume control are exactly what shared TV listening needs. If you have no such kit and just want one good-looking pair for music, calls and a cassette player, I would buy the We Are Rewind EQ-001. For a single buyer with no existing system, that is the one I would actually reach for — just check the current price on Amazon first, since neither product's value proposition changes but your budget might.
No. It is designed as an add-on headphone for the Avantree Duet, Quartet 5049 or Audiplex 2403s kits and is not intended to be purchased independently. Buy it only if you already own one of those transmitters.
It connects over Bluetooth 5.1, so it can pair with a Bluetooth-capable TV or source. Its listed latency is around 40ms, which is higher than the Avantree's ~30ms, so it is less ideal if tight lip-sync matters most to you.
The Avantree Add-on 2.4G is rated at 20 hours of playtime per charge, while the We Are Rewind EQ-001 is rated at 12 hours. Both take about 2 hours to charge.
Yes. It has a built-in digital MEMS microphone, a GO button for playback and call management, and double-click assistant activation for Siri or Google Assistant.
