How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a two-way Bluetooth hub for your TV that can also work as a transmitter for late-night viewing, choose miccus Long Range; if you need a dedicated hi-res receiver to feed a stereo or amplifier with LDAC, aptX HD and aptX Lossless, choose BluDento BLT-HD LDAC/aptX Lossless. These two boxes look similar on a spec sheet — both are small, both do Bluetooth audio, both promise long range — but they solve opposite problems. The miccus Home RTX 2.0 is built around sending audio out; the BluDento BLT-HD is built around pulling audio in. Get that direction wrong and neither one will do what you hoped, so the real question is which side of the chain you're trying to fix.
• miccus Long Range — biggest strength: it's a transmitter first, with aptX Low Latency for lip-sync-free TV, movie and gaming audio, dual-headphone pairing, and a claimed 300 ft outdoors / 160 ft indoors.
• miccus Long Range — biggest trade-off: it transmits or receives, never both at once, and the no-lag benefit only works if your headphones also support aptX Low Latency.
• BluDento BLT-HD — biggest strength: a receive-side Hi-Fi chain with Bluetooth 5.4, LDAC / aptX HD / aptX Lossless support, and a Texas Instruments PCM5102A 32-bit/384 kHz DAC feeding RCA, optical and coaxial outputs.
• BluDento BLT-HD — biggest trade-off: it's a receiver, so it won't send your TV's audio to a pair of Bluetooth headphones; range depends on walls, metal and your source device.
• Pick miccus Long Range if you want to watch TV on wireless headphones without waking the house, or add Bluetooth to an older TV over optical, RCA or 3.5mm.
• Pick BluDento BLT-HD if you want to stream from your phone or tablet into a vintage stereo, AVR, preamp or powered speakers at the highest codec quality that gear can accept.
The miccus Home RTX 2.0 is the "add Bluetooth to my TV" box, and it's unusually flexible about how it connects. It accepts digital optical (TOSLINK), RCA and 3.5mm stereo input, so it will happily sit behind a TV, a PC or a stereo that has no wireless of its own. Setup leans on voice prompts, LED indicators and included cables — the kind of thing you can hand to someone who doesn't want to read a manual. On the output side it pairs with headphones or speakers, and it can hold two headphones at once with independent volume per pair (volume is controlled by each paired device, not the box). That dual-link behavior is the standout feature for couples watching a movie at different volumes.
Who should buy it: anyone whose problem is getting audio out of a TV or PC into wireless headphones or speakers, especially with a soundbar already in the mix, and anyone who wants two listeners on one source. Who should skip it: if you want to stream music into an old amplifier, or you need LDAC/aptX HD quality, this isn't the tool. It also only handles audio Bluetooth — no other Bluetooth profiles — and phone/tablet pairing can need airplane mode first if it's being stubborn.
BluDento BLT-HD LDAC/aptX Lossless: Who It's For
The BluDento BLT-HD is the opposite animal: a pure receiver with an audiophile bent. Bluetooth 5.4 with LDAC, aptX HD, aptX Lossless, aptX, AAC and SBC covers basically everything a phone, tablet or computer can throw at it, and the Texas Instruments PCM5102A DAC (32-bit/384 kHz) is the part that matters most — it converts the incoming stream cleanly and hands it to your system at up to 2.1 Vrms over RCA, which is enough level to drive receivers, preamps and powered speakers properly.
Outputs are generous for a box this size (1"D x 3"W x 2"H, roughly 0.15 kg): RCA stereo plus optical (Toslink) and coaxial S/PDIF. That's the combination that makes it a natural fit for a vintage stereo that only has RCA inputs, or a modern AVR/DAC where you'd rather stay digital. Class 1 Bluetooth with an external gain antenna is what earns the "long range" claim, though BluDento is honest that actual distance depends on walls, metal obstacles and the source device — so don't expect a lab number in a brick house. Controls are simple, with app-based control and quick reconnection, and it supports common streaming services like Amazon Music, Pandora, YouTube, Netflix and iTunes content from your devices.
Who should buy it: anyone who wants to make a wired Hi-Fi system wireless without losing quality — a turntable-free streaming bridge into a 20-year-old integrated amp, or a cleaner path into powered monitors than the TV's own headphone jack. Who should skip it: if your goal is private TV listening on Bluetooth headphones, this won't do it. There's no transmit mode here, and no dual-headphone split.
• Best for TV and movie audio on wireless headphones → miccus Long Range. It transmits, supports aptX Low Latency for lip-sync, and pairs two headphones.
• Best for hi-res music into a stereo or amp → BluDento BLT-HD. LDAC, aptX HD and aptX Lossless in, TI DAC and RCA/optical/coaxial out.
• Best for mixed households → miccus Long Range. Soundbar plus two Bluetooth headphones simultaneously, with independent volume per listener.
• Best for older gear with only RCA inputs → BluDento BLT-HD. Its 2.1 Vrms RCA output and digital S/PDIF options slot into vintage and modern systems alike.
• Best for codec ceiling → BluDento BLT-HD. For anyone hunting aptx hd earbuds and a matching source chain, this is the side that actually supports aptX HD and LDAC — the miccus tops out at aptX/aptX-LL.
• Best for range in an open yard → miccus Long Range on paper, at up to 300 ft outdoors, though both makers warn that WiFi and obstacles eat into that.
• Best for simplicity → BluDento BLT-HD. Pair, connect, listen; no transmit/receive mode to think about.
• Best if you need flexibility in one box → miccus Long Range, since it can also work as a receiver — just never both directions at the same time.
In my opinion, most people searching this comparison are trying to fix a TV audio problem, and for that the miccus Long Range is the one I'd buy. Transmit mode, aptX Low Latency, dual-headphone support and optical/RCA/3.5mm inputs cover the messy reality of living-room gear. I'd only steer you to the BluDento BLT-HD if your actual goal is streaming your phone into a real stereo — in which case LDAC, aptX HD and that TI DAC make it the clearly better receiver. Decide the direction first; the rest sorts itself out. Either way, check the current price on Amazon before you commit.
FAQ
which earbuds support aptx hd
Yes — that's exactly its design. It takes optical, RCA or 3.5mm audio from your TV or PC and transmits to headphones or speakers, with aptX Low Latency for no-lag viewing when your headphones also support aptX-LL. It can pair two headphones at once with separate volumes.
No. The BLT-HD is a receiver — it takes Bluetooth audio in and outputs it over RCA, optical or coaxial. To get TV sound to wireless headphones you'd want a transmitter like the miccus, not this.
The miccus quotes up to 300 ft outdoors and 160 ft indoors, and notes WiFi interference can cut that. The BluDento uses Class 1 Bluetooth with an external gain antenna but says actual range varies with walls, metal and the source device. Both are honest that environment decides the outcome.
