How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a TV-first transmitter with a physical remote for volume and Optical passthrough to a soundbar, choose Avantree Oasis Plus 2; if you need a portable, battery-powered transmitter/receiver that also revives old speakers, car stereos and airplane seats, choose INCORIC 6.0.
• Avantree Oasis Plus 2 — biggest strength: It is built specifically around the TV. Optical (TOSLINK) and AUX inputs, Optical passthrough so your soundbar and your headphones can play at once, plus a hand-held remote for volume.
• Avantree Oasis Plus 2 — biggest trade-off: It is a corded, stationary box that lives next to your TV. It does not support HDMI ARC/eARC, AV receivers, or HDMI-only TVs, and it is not for hearing aids or Auracast.
• INCORIC 6.0 — biggest strength: It is a battery-powered, pocket-sized adapter that works in both directions (TX and RX), runs 24+ hours per charge, charges over USB-C in about 1.5 hours, and reaches up to 33ft.
• INCORIC 6.0 — biggest trade-off: It is a general-purpose gadget rather than a TV accessory. There is no remote, no Optical input and no Optical passthrough, so it connects over 3.5mm AUX or RCA only.
• Who each is for: Avantree Oasis Plus 2 is for a household that wants private TV listening without giving up the soundbar. INCORIC 6.0 is for someone who wants one small adapter for flights, the gym, the car and old hi-fi gear.
The Avantree Oasis Plus 2 is a Bluetooth TV transmitter with a very narrow, very deliberate job. It takes audio from a TV's Optical (SPDIF) or 3.5mm AUX output and sends it wirelessly to Bluetooth headphones or Bluetooth speakers. The important part is what it does on the way: Optical passthrough means the TV audio can still run to an OPT soundbar while the same audio goes to your headphones. So one person can listen loud through the speakers and another can listen at their own volume in private — simultaneously.
That passthrough behaviour is the reason this product exists. Most cheap transmitters force a choice: either the TV speakers or the headphones. Here you get both, and the Optical path keeps the signal digital end to end.
The second thing it gets right is volume. There are buttons on the transmitter itself, and Avantree also includes a hand-held remote. You adjust the level of what you are hearing without digging into TV menus or getting up. For anyone whose TV settings are buried three submenus deep, that is a genuinely practical detail rather than a spec-sheet flourish.
It also supports two Bluetooth headphones at the same time. For a couple watching a late film, or a parent and child sharing a programme at different volumes, that is the whole point. Latency is handled by aptX-Adaptive and aptX Low Latency support, which matters for lip-sync on dialogue-heavy content. Supported media types listed are MP3 and WAV, output mode is stereo, and the unit is black, corded, and weighs around 0.3 kg — a small box that sits on a shelf and stays there.
Who should buy it: anyone with a TV that has Optical or AUX output who wants private listening for one or two people while keeping a soundbar in the loop. Who should skip it: owners of HDMI-only TVs, anyone routing audio through an HDMI ARC/eARC connection or an AV receiver, and anyone shopping for hearing aids — this model does not support Auracast and will not work with them. If you need hearing-aid-friendly audio, look at Avantree's Oasis Aura instead.
The INCORIC 6.0 (model BT-25) is a different species of device. It is a Bluetooth 6.0 audio transmitter and receiver built on a Qualcomm chip, with aptX-Adaptive, aptX HD and Lossless support in the transmit direction. It is battery powered, charges over USB-C in about 1.5 hours, and INCORIC rates playtime at 24+ hours. It weighs almost nothing — the battery alone is listed at 5.8 g — and the shell is white ABS plastic.
Because it does both TX and RX, it solves two problems with one box. In transmit mode you plug it into a non-Bluetooth source over 3.5mm AUX or RCA and send audio to wireless headphones or a speaker: an old stereo, a vintage radio, gym equipment, a car head unit, a TV with only analogue outputs, in-flight entertainment. In receive mode you flip it around and let two phones pair to it, which is how INCORIC frames the car-sharing scenario — two people sending audio to one system.
Dual Link works in the transmit direction too, so two pairs of headphones can listen at once. Range is rated up to 33ft (10m), which comfortably covers a large room, a gym floor or the inside of a vehicle. Controls are touch-based with volume adjustment, there is an LED indicator set, and a RESET button clears pairing history so you are not stuck in a menu loop when you move it between devices.
The feature list is broad by design: auto-sync, low latency, noise cancellation, hands-free calls, dual device connection. It is certified to FCC, CE, RoHS and BQB. INCORIC also bundles setup videos covering cars, TVs and headphones, and flags the most common failure mode honestly — headphones that are still latched onto your phone's Bluetooth will keep this adapter from holding the connection.
Who should buy it: frequent flyers, commuters, gym-goers, and anyone with old analogue gear they want to make wireless. Who should skip it: someone who wants a permanent TV solution with a remote and Optical passthrough. There is no remote here, no Optical port, and no optical passthrough — it is AUX and RCA only, and it is a small portable device rather than a shelf unit.
• Best for private TV listening with a soundbar still running → Avantree Oasis Plus 2. Optical passthrough is the deciding feature; INCORIC 6.0 has no equivalent.
• Best for adjusting volume from the sofa → Avantree Oasis Plus 2. Dedicated buttons plus an included hand-held remote.
• Best for travel, flights and the gym → INCORIC 6.0. Battery powered, 24+ hours of playtime, USB-C fast charge, pocket-sized.
• Best for old speakers, radios and car stereos → INCORIC 6.0. TX and RX modes plus 3.5mm AUX and RCA inputs cover gear the Avantree unit was never designed for.
• Best for a TV with only Optical or AUX output and no interest in HDMI → either, but I'd lean Avantree Oasis Plus 2 for the remote and passthrough.
• Best for connecting two headphones at once → both. Each supports two simultaneous Bluetooth headphones; the difference is the source, not the headphone count.
• Best for low-latency movie and gaming audio → both. Each supports aptX Low Latency, with the INCORIC adding aptX HD/Lossless claims and auto-sync.
• Best for a household that also wants a second listening position in the car → INCORIC 6.0, because its receive mode lets two phones feed one system.
My Verdict
They are not really competing for the same job. If your TV has Optical output and you keep a soundbar, the Avantree's passthrough and remote make it the more useful box. If you need one adapter for flights, cars and old speakers, the INCORIC is the better fit. Check the current price on Amazon before deciding, since value depends on what you are replacing.
No. It connects over Optical (TOSLINK) or 3.5mm AUX, and HDMI ARC/eARC passthrough is explicitly not supported. It also will not work with HDMI-only TVs or AV receivers. If your TV only exposes audio through HDMI ARC, neither of these is a plug-and-play answer without an extractor.
Both. It is a dual-mode TX/RX adapter, so it can send audio from an AUX or RCA source to Bluetooth headphones, or receive audio from two phones into a wired system. Note that INCORIC states it can only transmit audio in the TV use case — the receive mode is aimed at car and speaker setups.
The INCORIC 6.0, clearly. It is battery powered with 24+ hours of rated playtime and USB-C charging in about 1.5 hours. The Avantree Oasis Plus 2 is a corded-electric unit designed to sit permanently beside your TV, so unplugged use is not part of its design.
