If you want one box that frees your TV, PC or stereo from wires and reaches across the house, choose miccus Long Range; if you need a pocket transmitter built for in-flight movies and long-haul travel, choose Avantree SoundJet R1-25Hr. In my opinion that single split decides it for most people — and if you're a side sleeper hunting for the best on-ear headphones for side sleepers, or the best memory foam ear cushions over-ear headphones for side sleepers, or even the best ANC sports earbuds for side sleepers, the transmitter you pair with matters as much as the headphones themselves. The one thing both units share is that they only unlock their best audio when your headphones speak the same codec — which is why "aptx hd earbuds" is the phrase that should be running through your head before you buy either one.
• miccus Long Range — biggest strength: genuine long-range reach (up to 300 ft outdoors, 160 ft indoors) plus dual-headphone output with independent volume, and it works with optical, RCA or 3.5mm sources.
• miccus Long Range — biggest trade-off: it transmits or receives, never both at once, and it's audio-only — no phone calls, no data. It also needs a mains-style USB power source, so it lives next to your TV, not in your pocket.
• Avantree SoundJet R1-25Hr — biggest strength: 25 hours of playback on one charge with USB-C pass-through charging, so a long flight never cuts your movie short, plus a dual-prong airline adapter in the box.
• Avantree SoundJet R1-25Hr — biggest trade-off: it is a transmitter only, and it needs a 3.5mm analog output — so it's useless on a TV without a headphone jack, and it isn't meant for calls or instruments.
• Who each pick is for: miccus for the home setup — TV, gaming, stereo, two listeners at different volumes; Avantree for the traveller — planes, gym machines, tablets, one screen shared by two people.
The miccus Long Range (Home RTX 2.0) is a home-base audio bridge. Its whole reason for existing is range and flexibility: it streams up to 300 ft outdoors and 160 ft indoors, which is the kind of reach that lets you wander into the kitchen or out to the yard without the signal dropping. It handles optical (TOSLINK), RCA and 3.5mm stereo inputs, so it can pull audio from a TV, a PC or a stereo receiver and push it to Bluetooth headphones or speakers. And it supports aptX and aptX-LL — the low-latency side is what keeps lip-sync tight for movies and gaming, provided the paired device supports aptX-LL too.
Who should buy it? Anyone who wants to add Bluetooth to an older TV or stereo, wants long reach around the house, or wants two people listening to one source at different volumes. It's also a natural fit if your headphones support aptX or aptX-LL, because that's where the latency benefit actually shows up. Who should skip it? People who need a transmitter and a receiver working simultaneously — this does one or the other, not both. Anyone hoping to use it for calls or non-audio Bluetooth should look elsewhere. And if your source has no audio output at all, no transmitter can help. One practical note worth repeating from the specs: Wi-Fi can interfere with range, so the recommended routine is to turn Wi-Fi off, set up Bluetooth, then turn Wi-Fi back on while audio streams.
Avantree SoundJet R1-25Hr: Who It's For
The Avantree SoundJet R1-25Hr is a travel tool, and it's honest about it. It's an airplane Bluetooth adapter: you plug its 3.5mm transmitter into an airline seat screen, a gym machine, a tablet or any other analog output, and it sends that audio to your Bluetooth headphones. The included dual-prong airline adapter covers both common seat-jack formats, which is the detail that saves you from hunting for a converter at 30,000 feet. Two people can pair two sets of headphones at once and share one screen, with dedicated connection indicators so you can see when each pair is ready.
The headline spec is 25 hours on a charge — and USB-C pass-through charging means you can keep listening while it tops up, so a long-haul flight doesn't have to interrupt the movie. Under the hood it uses a Qualcomm chipset with aptX Adaptive and aptX HD support for compatible headphones, plus Bluetooth 5.3. That's the part that matters for anyone searching for aptx hd earbuds: the adapter will negotiate the best codec both ends support, so headphones that can do aptX HD or aptX Adaptive get the better link, while AirPods and other headphones fall back to whatever they support. It's metal-bodied, button-controlled, battery-powered (a single included lithium-ion cell), and supports MP3, WAV, AAC and FLAC.
Who should buy it? Frequent flyers, commuters, gym-goers and tablet users who want their own headphones on a shared screen — especially two people travelling together. Who should skip it? Anyone wanting to Bluetooth-enable a TV: it needs a 3.5mm headphone output, so a TV without one is out. It's also not a Bluetooth receiver, not for phone calls, and not for musical instruments. Pairing quality depends on the headphones you bring.
• Best for range around the house → miccus Long Range. Up to 300 ft outdoors and 160 ft indoors is a home-scale figure; the Avantree is a short-reach personal transmitter.
• Best for battery life and travel → Avantree SoundJet R1-25Hr. 25 hours on one charge, with USB-C pass-through charging so charging doesn't stop playback.
• Best for two listeners at different volumes → miccus Long Range. It pairs two headphones with independent volume and lets your soundbar play at the same time.
• Best for two travellers sharing one screen → Avantree SoundJet R1-25Hr. Two headphones, one in-flight movie, connection indicators for each.
• Best for older TVs and stereos → miccus Long Range. Optical, RCA and 3.5mm inputs cover gear the Avantree simply can't reach.
• Best for aptX HD / aptX Adaptive headphones → Avantree SoundJet R1-25Hr. Qualcomm chipset with aptX Adaptive and aptX HD support, plus Bluetooth 5.3.
• Best for low-latency movie and gaming audio at home → miccus Long Range. aptX Low Latency keeps lip-sync tight, as long as your paired device supports it too.
• Best for a no-fuss, pocketable setup → Avantree SoundJet R1-25Hr. Metal body, button control, battery powered — nothing to plug into a wall.
I'd buy the miccus Long Range if my problem is at home — a TV, a stereo or a PC that I want to hear on headphones anywhere in the house, with two people able to listen at their own volume. The range, the input options and the dual-headphone output are the reasons, and for a side sleeper building a late-night listening setup, that flexibility is the whole point. I'd buy the Avantree SoundJet R1-25Hr if my problem is on the move — a long flight, a gym machine, a tablet — where 25 hours and a pocketable metal transmitter win. If you own aptX HD or aptX Adaptive headphones, the Avantree squeezes more out of them on the road; the miccus squeezes more out of your living room. Check the current price on Amazon before you commit, since that's the one variable I can't weigh for you.
FAQ
which earbuds support aptx hd
Only if your TV has a 3.5mm headphone output. The SoundJet R1 is a transmitter that takes analog 3.5mm audio and sends it to Bluetooth headphones — it isn't a Bluetooth receiver and isn't designed for TVs without that jack. For a TV with optical or RCA outputs, the miccus Long Range is the better fit.
It can transmit or receive, but not both at the same time — you choose one mode. It's also audio-only, so it won't handle other Bluetooth profiles, and if pairing gives you trouble the spec sheet suggests putting phones and tablets in airplane mode first.
Up to 25 hours on one charge, and USB-C pass-through charging lets you keep listening while it charges. That's the spec that makes it suited to long-haul flights rather than short hops.
