Are you tired of being stuck with wired headphones while watching TV at night? Do you want to enjoy your favorite shows without disturbing others in the room?
The Avantree Bluetooth transmitter has been a fan favorite for years. It turns almost any non-Bluetooth device into a wireless audio streaming machine. But in 2026, with new competitors and updated technology, does Avantree still hold its ground?
In this review, we take a deep dive into the Avantree Bluetooth transmitter lineup. We cover the Oasis Plus 2, Audikast Plus, and Audikast 3.
Key Takeaways:

- Range goes up to 164 feet on the Oasis Plus 2 and up to 100 feet on the Audikast models. This gives you freedom to move around your home without losing audio connection.
- Avantree uses Qualcomm chipsets in its latest models. This improves sound stability, connection strength, and overall audio clarity compared to generic Bluetooth adapters.
What Is the Avantree Bluetooth Transmitter?
The Avantree Bluetooth transmitter is a small device that adds wireless audio capability to non-Bluetooth devices. It works with TVs, PCs, AV receivers, and other audio sources. You connect it to your device’s audio output, and it sends sound wirelessly to your Bluetooth headphones or speakers.
Avantree has been in the Bluetooth audio business for over a decade. The company is owned by Avantronics and focuses on creating affordable wireless solutions. Their products stand out because they use Qualcomm Bluetooth chipsets. These chips deliver better audio quality and more stable connections than many budget alternatives.
The transmitter lineup includes models like the Oasis Plus 2, Audikast Plus, and Audikast 3. Each model targets a slightly different user. Some people want a feature-packed device with remote control. Others want a simple plug-and-play transmitter at a lower price.
What makes Avantree different from generic Bluetooth adapters? The answer is codec support. Avantree transmitters support aptX Low Latency, aptX Adaptive, and SBC codecs. This wide codec support means you get low delay audio with most quality Bluetooth headphones. If you have ever experienced a frustrating lip-sync issue while watching TV with wireless headphones, Avantree solves that problem.
Avantree Oasis Plus 2 Bluetooth Transmitter
The Avantree Oasis Plus 2 is the flagship Bluetooth transmitter in the Avantree lineup. It runs on Bluetooth 5.3 and supports aptX Adaptive, aptX Low Latency, and SBC codecs. This model is built for serious home entertainment users who want the best wireless audio experience.
One of the biggest selling points is the remote volume control. You can adjust the volume of your Bluetooth headphones without getting up from the couch. This is a feature many competitors still lack. The included remote makes it easy to change volume levels, switch between paired devices, and control playback.
The Oasis Plus 2 also supports soundbar passthrough. This means you can keep your soundbar connected while also streaming audio to your headphones. You do not have to unplug anything or switch cables. The optical passthrough sends audio to both your soundbar and your wireless headphones at the same time.
Range is impressive at up to 164 feet (50 meters) in open space. In a typical home setting with walls, you can expect around 50 to 80 feet of reliable connection. The unit connects via optical (TOSLINK) or 3.5mm AUX input. It also supports dual link, letting two headphones connect at once.
The device weighs only 90 grams and uses a USB-C port for power. It draws between 500mA and 2A at 5V, so any standard USB charger works fine. Setup is straightforward and takes just a few minutes.
Avantree Audikast Plus Bluetooth Transmitter
The Avantree Audikast Plus is a popular mid-range option. It offers Bluetooth 5.3 with aptX Adaptive and aptX Low Latency support. This model provides excellent sound quality at a more affordable price than the Oasis Plus 2.
It supports four different audio inputs: optical (TOSLINK), AUX 3.5mm, RCA, and USB audio. This wide input range means it works with almost any TV or audio source you own. Older TVs with only RCA outputs work just as well as newer models with optical ports.
The Audikast Plus features a built-in volume boost for optical connections. Many users report that optical audio output from TVs can be quieter than expected. The Audikast Plus addresses this by boosting the volume up to 6dB. This makes a real difference, especially for users with hearing difficulties.
Dual link support is included here too. You can pair two Bluetooth headphones at the same time. Both listeners hear the audio simultaneously with minimal delay. The operating range reaches up to 100 feet (30 meters), which covers most living rooms and bedrooms easily.
Top 3 Alternatives for Avantree Bluetooth Transmitter
If the Avantree lineup does not match your exact needs, here are three strong alternatives worth considering.
The 1Mii B06TX is a budget-friendly Bluetooth 5.3 transmitter. It supports optical, RCA, coaxial, and AUX inputs. It also features a built-in volume control knob and connects to two headphones at once. This is a solid option if you want versatility at a low price.
The Sennheiser BT T100 comes from a premium audio brand. It delivers clean Bluetooth audio with aptX and AAC codec support. It connects via a 3.5mm input and is very compact. If you value brand reputation and audio purity, this one is worth a look.
The Twelve South AirFly Pro is a portable Bluetooth transmitter and receiver. It works great for airplane entertainment systems, gym equipment, and TVs. It supports two headphones at once and has a 16-hour battery. This is the best pick for users who need a travel-friendly option.
Sound Quality and Audio Performance
Sound quality is the most important factor for any Bluetooth transmitter. Avantree delivers clear, detailed audio across its product range. The aptX Adaptive codec provides high-quality streaming that adjusts dynamically to your connection conditions.
Low latency is where Avantree truly shines. With aptX Low Latency enabled headphones, audio delay drops to around 40 milliseconds. This is fast enough that most people cannot detect any lip-sync issues. You can watch movies, play games, and enjoy live sports without noticeable audio lag.
The Oasis Plus 2 handles PCM and LPCM audio formats through its optical input. This covers standard TV audio output. The Audikast models also accept digital and analog signals. Analog inputs (AUX and RCA) work well for older devices that lack digital audio outputs.
Volume boost on the Audikast models is a feature many users appreciate. Optical audio from TVs often outputs at a fixed, sometimes low, volume level. The built-in boost compensates for this and gives you louder, clearer sound through your headphones.
Setup Process and Ease of Use
Setting up an Avantree Bluetooth transmitter takes less than five minutes for most users. The process is simple and does not require any technical knowledge.
First, you connect the transmitter to your TV’s audio output. You can use optical (TOSLINK), AUX 3.5mm, or RCA, depending on the model. Next, you plug the USB power cable into the transmitter and connect it to a USB port on your TV or a wall adapter. The device powers on automatically.
Then, you put your Bluetooth headphones into pairing mode. Press the pairing button on the Avantree transmitter. The two devices find each other and connect within seconds. Once paired, the transmitter remembers your headphones. It reconnects automatically every time you power it on.
The Oasis Plus 2 adds the convenience of a remote control. You can switch between paired devices, adjust volume, and manage connections from across the room. The Audikast models use physical buttons on the unit itself. These buttons are clearly labeled and easy to press.
Bluetooth Range and Connectivity
Bluetooth range varies by model. The Oasis Plus 2 leads the pack with an impressive 164-foot (50-meter) range in open space. The Audikast Plus and Audikast 3 offer up to 100 feet (30 meters).
In real-world conditions, walls and obstacles reduce these numbers. You can expect reliable connections within 50 to 80 feet inside a typical home. This covers most common scenarios. You can walk to the kitchen, bathroom, or another room and still hear your audio without interruptions.
All current Avantree transmitters use Bluetooth 5.3 technology. This newer version provides better power efficiency, stronger signal stability, and improved interference handling compared to older Bluetooth versions. You get fewer dropouts and more consistent audio.
The dual link feature lets you connect two Bluetooth headphones at the same time. Both headphones receive audio simultaneously. This is perfect for couples watching TV together or parents monitoring audio while a child watches a show. The connection remains stable even with two devices linked.
Avantree Audikast 3 Bluetooth Transmitter
The Avantree Audikast 3 is the newest addition to the Audikast line. It runs on Bluetooth 5.3 with a Qualcomm chipset inside. It supports aptX Adaptive and aptX Low Latency codecs. This model targets users who want updated technology without the premium price of the Oasis Plus 2.
Key features include dual headphone connection, 100-foot range, and both optical and AUX audio inputs. The volume boost feature carries over from the Audikast Plus. Optical audio gets a 6dB lift for louder and clearer output.
The Audikast 3 improves on its predecessor with a more stable Bluetooth connection and better power efficiency. The Qualcomm chip handles interference more effectively. This results in fewer audio dropouts during long listening sessions.
Build quality is solid with a compact ABS plastic shell. The unit sits discreetly behind a TV or entertainment center. LED indicators show connection status and codec type at a glance. The device draws power through USB, so it stays simple and cable-free.
Pros and Cons of Avantree Bluetooth Transmitters
Every product has strengths and weaknesses. Here is an honest look at what Avantree gets right and where it falls short.
The pros are significant. Sound quality is excellent for the price range. The aptX Low Latency support eliminates lip-sync problems that plague cheaper transmitters. Dual headphone support is a rare feature at this price. Setup is fast and simple. The Qualcomm chipset delivers stable, long-range connections. Build quality is solid across all models.
The Oasis Plus 2’s remote control sets it apart from almost every competitor. Adjusting volume without touching the transmitter is a luxury that quickly feels essential. The soundbar passthrough feature also adds real convenience.
The volume boost on Audikast models solves a common complaint about low optical output. This small feature makes a big difference for many users.
Now for the cons. Avantree transmitters do not decode Dolby Digital or DTS audio. You must set your TV to output PCM. This is easy to do but can confuse first-time users. The Audikast models lack a remote control, so you must walk to the device to change settings.
Bluetooth compression means you will not get lossless audio quality. This is true of all Bluetooth transmitters, not just Avantree. Audiophiles who demand perfect sound may prefer a dedicated wireless headphone system instead.
How Does Avantree Compare to Competitors?
Avantree holds a strong position in the mid-range market. Its main competitors include the 1Mii B06TX, Sennheiser BT T100, and Twelve South AirFly Pro.
Against the 1Mii B06TX, Avantree offers better codec support and a Qualcomm chipset. The 1Mii is cheaper and includes a coaxial input that Avantree lacks. For pure value, the 1Mii wins. For audio quality and reliability, Avantree has the edge.
The Sennheiser BT T100 carries a trusted brand name. It sounds great and looks sleek. But it only has a 3.5mm input and supports fewer codecs than Avantree. It also costs more for fewer features. Avantree wins on versatility and value.
The Twelve South AirFly Pro is a portable option with a built-in battery. It excels for travel and airplane use. But it is not ideal as a permanent home setup. Avantree’s dedicated TV transmitters outperform it for home entertainment.
Avantree Bluetooth Transmitter Pricing and Value
Pricing varies by model and retailer. The Audikast Plus typically sells for around $40 to $50 on Amazon. The Audikast 3 sits in a similar range. The Oasis Plus 2 costs between $60 and $80, depending on current deals and promotions.
For the features you get, Avantree offers excellent value. Many competitors charge similar prices but lack aptX Low Latency support, dual headphone connection, or Qualcomm chipsets. You get premium-level features without paying a premium price.
Avantree frequently offers bundle deals on Amazon. You can find the Oasis Plus 2 paired with headphones or the Audikast 3 bundled with a portable speaker. These bundles save money if you need both a transmitter and a listening device.
The 24-month warranty adds long-term value. If your device fails within two years, Avantree replaces it. Their customer support team has positive reviews on Trustpilot and Amazon. Users report helpful and responsive service.
Customer Reviews and Real User Feedback
Customer feedback paints a positive picture for Avantree transmitters. On Amazon, most models hold ratings between 4.0 and 4.5 out of 5 stars. Users praise the easy setup, reliable connections, and clear audio quality.
Positive reviews commonly mention the elimination of lip-sync issues. Users who switched from cheap Bluetooth adapters notice an immediate improvement. The dual headphone feature also receives frequent praise from couples and families.
Some users report initial confusion with audio settings. The most common issue involves TVs outputting Dolby Digital instead of PCM. Once users change their TV audio settings, the problem disappears. Avantree includes clear instructions for this in their user guide.
Range performance gets mixed reviews. In open spaces, users confirm the advertised distances. In homes with thick walls or lots of wireless interference, range decreases. This is standard for Bluetooth devices and not unique to Avantree.
Long-term reliability is another strong point. Many reviewers report using their Avantree transmitter daily for over a year without issues. The devices run cool and show no signs of degradation over time.
Final Verdict: Should You Buy an Avantree Bluetooth Transmitter in 2026?
The Avantree Bluetooth transmitter lineup remains a top choice in 2026. The Oasis Plus 2 is the best option for users who want premium features like remote control and soundbar passthrough. The Audikast Plus and Audikast 3 deliver strong performance at a lower price.
If you need low latency wireless audio from your TV, Avantree is one of the safest bets on the market. The Qualcomm chipsets, aptX codec support, and dual headphone connections set it apart from budget competitors. Setup is painless, and long-term reliability is proven.
We recommend the Oasis Plus 2 for most home users. It offers the most complete package. For budget-conscious buyers, the Audikast 3 provides the best balance of modern features and affordability.
Avantree continues to earn its reputation as a leader in Bluetooth audio accessories. Whether you are a late-night TV watcher, a gamer, or someone who wants to upgrade older audio equipment, there is an Avantree transmitter that fits your needs.
Frequently Asked Questions
Does the Avantree Bluetooth transmitter work with AirPods?
Yes. All Avantree Bluetooth transmitters work with Apple AirPods. The transmitter uses standard Bluetooth pairing. Simply put your AirPods in pairing mode and press the connect button on the Avantree device. Note that AirPods use the AAC or SBC codec, so you may not get the lowest possible latency compared to aptX-compatible headphones.
Can I use an Avantree transmitter with my soundbar at the same time?
The Avantree Oasis Plus 2 supports optical passthrough. This lets you send audio to both your soundbar and your Bluetooth headphones simultaneously. The Audikast models do not include this feature. You would need to use a separate audio splitter with those models.
How do I fix lip-sync delay with my Avantree transmitter?
Make sure your Bluetooth headphones support aptX Low Latency or aptX Adaptive codecs. Also, set your TV’s audio output to PCM instead of Dolby Digital or Bitstream. This combination eliminates most lip-sync issues. If delay persists, check your TV’s audio delay settings.

No. Avantree Bluetooth transmitters are powered through a USB cable. You can plug the USB cable into a USB port on your TV or use any standard USB wall adapter. The device draws minimal power and runs continuously as long as it receives USB power.
How many headphones can connect to an Avantree transmitter?
Most Avantree transmitters support dual link, meaning you can connect two Bluetooth headphones at once. Both headphones receive the same audio stream simultaneously. This works best when both headphones support the same Bluetooth codec.
Is the Avantree Bluetooth transmitter compatible with hearing aids?
Avantree transmitters can work with Bluetooth-enabled hearing aids. The device sends a standard Bluetooth audio signal. If your hearing aids accept Bluetooth audio input, they should pair with the transmitter. Check your hearing aid’s Bluetooth compatibility before purchasing.
