This is valuable in a living room where a soundbar handles normal household viewing and wireless headphones are needed for one or two viewers. The product also accepts AUX input for compatible televisions.

Compatibility is narrower than on many general-purpose adapters. It does not support HDMI-only televisions, HDMI ARC, eARC, or AV receivers. It is also transmitter only and does not work with hearing aids or Auracast. Buyers whose television offers only HDMI may need an external audio extractor or a different transmitter architecture, and those who need phone-to-speaker reception should choose a two-way model.

The Oasis Plus 2 is a good choice for households seeking a dedicated TV adapter rather than a travel accessory. Its strongest combination is two-person Bluetooth listening, remote volume control, and simultaneous optical soundbar playback. If the television has optical or AUX output, those features make it a convenient and focused solution for shared homes and private viewing.

Personal volume without changing the TV

The included remote changes the transmitter's audio level independently, so a viewer can lower the headphone volume without altering the main television setting. Onboard buttons provide a convenient alternative when the remote is out of reach.

• Works in transmitter and receiver modes
• Bypass serves wireless and wired users
• Readable display aids configuration
• Multiple aptX codec options

Cons

• LDAC transmit limited to one device
• Low latency requires compatible receiver

We may earn a commission when you buy through this link, at no additional cost to you.

Bypass mode allows television audio to reach wireless headphones and a wired soundbar at the same time. That makes the B03Pro+ useful in a home with different listening needs, while its dual-device capability supports two Bluetooth listeners. A clear display helps users identify paired devices and choose the appropriate source, and built-in volume controls provide another way to manage output.

There are codec-specific constraints that buyers must understand. LDAC in transmitter mode works only with one paired headphone or speaker. Low-latency performance depends on the receiving device supporting aptX Low Latency; if it falls back to SBC, aptX, or another codec, a delay of roughly 70 to 200 milliseconds may occur. The device also cannot operate in transmitter and receiver modes simultaneously, and range can be reduced by walls, metal, or Wi-Fi.

The B03Pro+ is best for audiophiles or listeners who own compatible high-resolution wireless equipment and want more codec flexibility than a basic TV adapter provides. Its use of LDAC can be a decisive advantage for music and high-fidelity listening, while aptX Low Latency and bypass mode keep it relevant for television use. It is less suitable for buyers who prioritize simple two-listener travel over codec sophistication.

High-resolution wireless in both directions

LDAC support in transmitter and receiver modes differentiates the B03Pro+ from conventional SBC-based adapters. The full 24-bit/96kHz capability is available only when paired equipment supports LDAC and the connection is configured accordingly.

Audiophile features with practical limits

aptX Low Latency, LDAC, and dual-device operation create a flexible feature set, but the operating rules are more involved. One-device LDAC transmission, compatible endpoints, and correct PCM output settings on a television should be considered before purchase.

Buying Guide – How to Choose the Best Multipoint Bluetooth Transmitter

A multipoint Bluetooth transmitter should be judged by more than the number of devices it can pair. Source compatibility, codec behavior, latency, range, controls, power management, and the precise meaning of multipoint support all affect whether a device will work well in your home or travel routine.

Confirm the number of simultaneous listeners

The defining feature of a multipoint-style transmitter is that one source can feed two Bluetooth headphones or speakers at once. That is useful for couples, families, shared flights, and gaming sessions. However, two-device support does not always mean that every codec remains available in that mode. For example, the 1Mii B03+ switches from aptX Low Latency to standard aptX when two low-latency headphones are connected, while the B03Pro+ limits LDAC transmitter use to one paired device.

Choose based on your actual audience. Confirm that the product supports two Bluetooth audio outputs rather than merely two remembered devices, and review any codec changes that occur in multipoint mode.

Match the transmitter to the source

A multipoint transmitter is useless if it cannot connect to the equipment you already own. Common television outputs include 3.5mm headphone sockets, RCA stereo outputs, and optical or coaxial digital audio, while airplane entertainment usually uses one or two 3.5mm-style plugs. Some modern televisions expose only HDMI, and many adapters cannot accept HDMI, HDMI ARC, or eARC directly.

Check every available output before buying. If your source is HDMI-only, look for a product that explicitly supports that connection or plan to use a separate compatible audio extractor. Do not assume that a 3.5mm adapter can route television audio when the set has no analog output.

Decide between transmitter and receiver modes

A transmitter sends audio from a wired source to Bluetooth headphones. A receiver does the opposite, accepting phone, tablet, or computer audio and sending it to a wired stereo. Dual-mode products are more versatile, while a transmitter-only design may be simpler and better focused on television or airplane use.

Think about both current and future needs. A two-in-one adapter is sensible if you want to use existing speakers with phone music, but it may require switching modes manually and cannot necessarily perform both directions at once. Airplane-only products often omit receiver functionality to remain compact and uncomplicated.

Prioritize latency for video and games

Low latency is essential when sound must remain synchronized with moving images. Products in this roundup cite aptX Low Latency, while the newer adapters advertise near-zero latency. The wording alone does not guarantee identical performance, because the source, transmitter, codec, and headphones must negotiate a compatible format. If the receiving headphones do not support low-latency aptX, the connection may use another codec and introduce delay.

Look for explicit codec support and review the fallback behavior. A transmitter can sound excellent but feel wrong during a movie if dialogue arrives noticeably after the actors speak. Codec support on the transmitter should therefore be considered together with the capabilities of your existing headphones.

Evaluate range in the intended environment

Advertised maximum range is best interpreted as an ideal condition, not a guaranteed indoor distance. Some products cite line-of-sight figures of 164 or 230 feet, while others list more practical indoor ranges of 20 to 30 meters, and one Bluetooth 6.0 adapter specifies 40 feet for two headphones. Walls, furniture, metal objects, Wi-Fi interference, and the quality of the receiving device can all reduce the usable distance.

Choose the specification that matches the relevant room or travel scenario. For a television in a normal living room, a stated indoor range is more meaningful than a maximum outdoor figure. For an airplane, the two headphones are usually nearby, so quick pairing and stable short-range transmission matter more than maximum distance.

Check the connection and control options

Clear controls can make a shared audio setup much easier to manage. An LCD display helps identify the active source and paired devices, while onboard volume buttons are helpful when using earbuds that lack convenient physical controls. A remote is especially useful for television viewing because it lets one person adjust personal volume without changing the television setting or walking to the soundbar.

Auto-pairing and automatic reconnection are valuable for repeated use. A product that reconnects to two saved headphones is well suited to a nightly television routine, while airplane users may prefer a small indicator that clearly confirms connection status without requiring an app.

Account for battery life and charging

Portable transmitters need enough battery life to cover the length of a flight, game session, or several evening viewings without an interruption. Stated battery figures in this roundup range from 18 hours to more than 24 hours, with several products also supporting use while charging through USB-C. A full charge is listed as taking approximately 1.5 hours on the portable Bluetooth 6.0 models.

For home use, a receiver operating continuously should be connected to a suitable power source. For travel, consider battery life, charging port availability, and whether the included cables are adequate for your trip. A longer stated runtime is useful, but reliable controls and quick reconnection are often more noticeable in daily use.

Recognize specialist and compatibility limits

Every product has a defined use case. The Avantree Relay is transmitter only and is not intended for television, calls, hearing aids, instruments, or receiving audio. The SOOMFON adapter lacks a microphone, uses SBC, and is not compatible with hearing aids or devices requiring a pairing PIN. The Avantree Oasis Plus 2 does not support HDMI, ARC, eARC, AV receivers, Auracast, or hearing-aid use.

Review these exclusions before ordering. They do not make the products poor choices; they make them specialized choices. Confirm that the exclusion involving your planned use is not a core requirement, and verify codec and source compatibility with every device that must be connected.

How to Use and Care for Your Multipoint Bluetooth Transmitter

Begin by identifying the correct output on the source device. For a television, choose 3.5mm, RCA, optical, or coaxial according to the adapter's supported inputs. For airplane use, determine whether the seatback connector uses a single or dual plug, then attach the appropriate adapter. Connect the cable securely before powering the transmitter, and set a television's digital audio output to PCM when using an optical connection.

Place the transmitter in pairing mode, then put both Bluetooth headphones or speakers into their own pairing mode. Once the devices appear, select them from the transmitter's pairing list. After the first successful connection, confirm that both devices reconnect automatically. If synchronization or latency is poor, check whether the active codec changed because two devices are connected and whether every endpoint supports the codec advertised by the product.

For regular care, keep the charging port and audio sockets free of dust, protect the device from moisture and extreme heat, and use the specified charging method. When switching between transmitter and receiver modes, complete the mode change before attempting to pair. If a connection becomes unreliable, forget the saved devices on the headphones, clear the transmitter's pairing memory according to its manual, and begin the pairing process again.
