If you want long-range TV audio around the house, choose miccus Long Range; if you need a compact Bluetooth adapter for travel, choose Avantree Relay & Voyager. For webinars, the miccus has the clearer fit when you want to route audio from a TV or computer to Bluetooth headphones; the Avantree is built around a 3.5mm AUX connection and portable use.
• miccus Long Range’s strength: It can transmit audio up to 300 feet outdoors or 160 feet indoors, and it supports optical, RCA, and 3.5mm connections. Its trade-off is that it transmits or receives, but cannot do both at once; WiFi can also affect range.
• Avantree Relay & Voyager’s strength: Its pocket-sized, battery-powered adapter has Bluetooth 5.3, an OLED display, and built-in controls for pairing, volume, and battery information. Its trade-off is that its audio input is 3.5mm AUX, and it is not compatible with phones, car stereos, or hearing aids.
• Choose miccus Long Range if you want to connect a TV, PC, or stereo to as many as two headphones and value reach around the home.
• Choose Avantree Relay & Voyager if you want a compact adapter for an AUX audio source and travel-oriented use.
The miccus Long Range is a Bluetooth audio transmitter or receiver for a TV, PC, or stereo. It has optical, RCA, and 3.5mm connection options, so it can suit setups where the audio source offers a different output than a basic AUX jack. Voice prompts and LED indicators help with setup, and the included cables give you options for connecting it to compatible audio equipment.
Its headline advantage is reach: the stated range is up to 300 feet outdoors and 160 feet indoors. That could be useful when you want to listen away from the TV, or move between rooms without staying close to the audio source. Those figures are not a promise for every home, though. The product notes that WiFi can affect range and recommends establishing the Bluetooth connection before turning WiFi back on.
For webinars, I’d consider it when the audio is coming from a TV or PC and you want a transmitter that supports up to two headphones. It also supports aptX Low Latency, which is intended to reduce lip-sync delay, but the paired headphones must support that codec too. Skip it if you need a device that transmits and receives at the same time, or if your setup depends on a feature beyond audio.
The Avantree Relay & Voyager is a travel-focused Bluetooth adapter with a 3.5mm AUX input. Its compact, pocket-sized design and battery power make it easier to carry than a home-oriented transmitter setup. The product is presented for connecting Bluetooth headphones to an AUX audio source, including an airplane audio jack.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
The feature set emphasizes straightforward control while you’re using it. Built-in controls can adjust volume, pair or reconnect headphones, clear pairing history, and show battery information. An OLED display and LED indicators provide connection and battery details. Bluetooth 5.3 and support for aptX Adaptive, aptX HD, and aptX Low Latency describe its wireless and codec capabilities; the listening device also needs compatible codec support to benefit from a particular codec.
This may suit someone who wants a portable adapter for headphones such as AirPods or Bose models, or wants one for travel and gym sessions. It is not a general-purpose phone or car-stereo adapter: the listed compatibility excludes phones, car stereos, and hearing aids. Skip it if you need optical or RCA input, or want to connect a phone directly as the audio source.
• Best for longer stated range → miccus Long Range. Its figures are up to 300 feet outdoors and 160 feet indoors. The Avantree sheet does not specify a range.
• Best for a TV with optical audio → miccus Long Range. It supports digital optical, as well as RCA and 3.5mm connections.
• Best for a simple AUX travel setup → Avantree Relay & Voyager. Its 3.5mm AUX input and pocket-sized design are aimed at portable use.
• Best for connecting two headphones → miccus Long Range. It supports up to two headphones, with separate volume adjustment through each paired device.
• Best for built-in battery and connection information → Avantree Relay & Voyager. It is battery-powered and includes an OLED display and LED indicators for connection and battery details.
• Best for reducing TV lip-sync delay → miccus Long Range, with a condition. It supports aptX Low Latency, but the paired headphones must support it as well. The Avantree also lists aptX Low Latency support, with the same need for compatible listening equipment.
• Best for switching between transmitter and receiver use → miccus Long Range. It can operate in either mode, though not both simultaneously.
• Best for in-ear earbuds for webinars → Avantree Relay & Voyager when the audio source has a 3.5mm AUX output. Its listed compatibility includes Bluetooth headphones, while the miccus may suit a webinar setup better when the source is a TV or PC and range or multiple headphones matters.
Before choosing, check the audio output on the device you plan to connect. The miccus has optical, RCA, and 3.5mm options, which gives it more flexibility for home audio equipment. The Avantree’s listed input is 3.5mm AUX, a straightforward match for a compatible AUX source but a limitation if your setup needs optical or RCA.
Also consider where you will use the adapter. The miccus is designed around connecting a TV, PC, or stereo and gives specific outdoor and indoor range figures, with a warning that WiFi may interfere. The Avantree is described as pocket-sized and travel-ready, but its data does not specify range or battery runtime. Neither product’s listed facts establish that it is the best waterproof Bluetooth earbuds for webinars: the sheets do not state that either adapter is waterproof.
My Verdict
I’d choose the miccus Long Range for a home webinar setup connected to a TV or PC, especially if I wanted the option of two headphones or more reach around the house. Its broad range of audio connections makes it the more adaptable home choice.
For webinars on the go, I’d choose the Avantree when the source has a 3.5mm AUX output and portability matters more than home-range flexibility. My recommendation is the miccus for home use, not because it wins every category, but because its connection options and stated range better fit that use.
For a home setup connected to a TV or PC, the miccus is the more flexible fit because it supports optical, RCA, and 3.5mm connections, plus up to two headphones. The Avantree makes more sense for a portable AUX source.
Both list aptX Low Latency support. To use that codec, the paired headphones must support it too; codec support alone does not guarantee low-latency performance with every listening device.
Yes. The miccus supports up to two headphones, and each headphone’s volume is controlled through its paired device. It can also let a soundbar and Bluetooth audio operate together, according to its listed features.
The Avantree’s listed compatibility excludes phones, car stereos, and hearing aids. Its described use is to connect Bluetooth headphones to an AUX audio source, such as an airplane audio jack.
