## Features

- [WIDE COMPATIBILITY] The Audikast supports TVs with optical (TOSLINK) and AUX (3.5mm) audio output ports. Please check your TV's audio output options before purchase to ensure compatibility. With this product, you can connect Bluetooth headphones or earbuds to the transmitter and enjoy audio from your TV wirelessly.
- [Perfectly Synced Visual-Audio] The Avantree Oasis Plus is aptX Low Latency certified. When (and ONLY WHEN) used with a Bluetooth headphone/speaker that also supports aptX Low Latency or FastStream, it will deliver the ultimate “no lip sync delay” experience, ensuring perfectly synced visual and audio no matter what you watch.
- [Works Alongside your Speaker] The “Pass-Through” or “Bypass” feature of Oasis Plus guarantees simultaneous audio output through the headphones (that are connected to Oasis Plus) AND your external TV speaker such as Sound Bar or Stereo AVR, so other household members can still hear the TV while you’re using the headphones.
- [Two Headphones, Together] The Oasis Plus features a “dual-link” function that allows two Bluetooth headphones/speakers to be connected at the same time; audio will play through both devices simultaneously. Enjoy a late-night Netflix session with a partner, at your own volumes, without awaking others in your household.
- [Wide Compatibility] The Oasis Plus in Transmitter (TX) mode works with any TV that has an audio output port, and it can be paired with any headphone/speaker that’s Bluetooth enabled. In Receiver (RX) mode, it can receive wireless audio signals from your iPhone, iPad or Android via Bluetooth and stream audio into any wired speaker system.
- [Class 1 Long Range Bluetooth] Equipped with the highest Bluetooth range, Class 1 and the running Bluetooth version 5.0 ensures the Oasis Plus provides stable & reliable connectivity up to 164 ft (50 m). Need to start making dinner? No problem, do what you need to do without worrying about the audio cutting out.

## Questions & Answers

**Q: i need to connect wireless blue tooth headphones to a samsung tv**
A: Please use audio cable to wire connect it to your TV, and set both the transmitter and your wireless bluetooth headphone to the pairing model to pair them together to set them up. There are guidances and FAQs of it on our support website that you can check, or please feel free to contact our support team either by email or phone call, we will always try our best to help.

**Q: Can i connect this device to a windows xp desktop**
A: Yes but depending on the sound out of your pc. You would need either a 3.5mm stereo jack to come from the pc into 2xRCA which, I think, were supplied in the box. Or an optical to optical out (included).
If you have 2 RCA's for sound out then you would need a 2xRCA to 2xRCA cable.

**Q: Will it work with bose wireless speakers**
A: Yes, it will work with bose wireless speakers, please feel free to contact our support team for any help you need.

**Q: Can you connect a projector to this and then connect 4 bluetooth headphones**
A: As long as the projector has a 3.5 aux audio out and optical out port, you can connect it to this transmitter, but you can only pair two headphones at the same time to it, and better to use the ones that support aptx ll, to avoid audio delay. Please feel free to contact our support team for any help you need.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Decent quality, well designed
*by M***E on 16 July 2022*

I bought this to use bluetooth headphones to listen to TV. I want a better sound from TV but not bothered with surround sound, and mega bass, just decent stereo and fuller sound for listening to music on TV - concerts, documentaries etc., and Im not in a position to put TV between my Hi Fi speakers.The Oasis Plus is top spec Bluetooth 5 APTX low latency, and my main concern was that my 2 pairs of existing headphones were beneath this - one pair APTX BT 4 and one pair BT 4, not APTX, and neither were 'low latency' which apparently is an 'add-on' to APTX. The device is well designed with optical, 3.5mm jack and phono inputs (via adapter lead) , and all connecting leads are supplied along with a usb power lead.Set up using decent instructions supplied was pretty straightforward, and spoken guidance from device confirmed correct set up and pairing. Any latency would mean vision and audio were out of sync, but both pairs of headphones worked fine. As I was able to check latency by listening to TV internal speakers along with headphones, I could hear a slight 'echo/delay' - indicating very slight latency, but this was so slight that using headphones alone, there appeared to be decent sync with video on screen, very satisfied with result. I was listening about 3-4 metres from TV with a clear line of sight to transmitter. I was also able to walk out of my lounge into kitchen with no loss of signal.The device can also be used as a receiver - for instance to play bluetooth devices into a hi fi with no bluetooth - there is an identical set of connections on rear of device for receiver mode, and these can also be brought into play if you want to connect a TV soundbar in transmitter mode , along with headphones - they call this 'pass through'.A well designed device which worked perfectly for me.

### ⭐⭐⭐⭐⭐ Ideal for upgrading a TV or an old desktop for bluetooth sound
*by T***K on 2 January 2020*

I’ve an old tower desktop pc that needed a decent sound card. I went with an external dac soundcard (a Fiio E17). The dac is connected to by 3.5mm audio cable to this Avantree transmitter to send the audio to speakers and airpods.To my ear, this arrangement worked exceptionally well. I’ve used it to watch/listen to Amazon’s primevideo, Netflix, youTube and classicfm. I’m not an audiophile but enjoy listening to the individual tones in high quality classical music tracks. There is no noticeable lack of synchronisation between the video and audio.Quick setup guide - the buttons explained - transmitter modeBottom right are ‘plus’ and ‘minus’ for volume control. Holding both down clears the bluetooth paired memory.Bottom left is the pairing button. Touching this will make the light above it flash quickly and it will automatically pair with a speaker that’s in pairing mode. Alternatively, if the unit is set to ’Rx’, receive, this button will enable pairing with a pc/phone/bluetooth player.Next to this button is the ‘aux/opt’ for switching input between the use of 3.5mm audio cable and optical audio cable. Holding this button down for 7 seconds will disable the voice prompts which are handy for initial use.Pros1. There is no internal battery which could be good for use with a desktop pc as batteries need care and maintenance. I’ve also used it with a TV to enable bluetooth sound output; the ‘no battery’ renders it a simple ‘plug-in and forget’ device - it’s perfect in this role.2 The range is pretty good. It works at seven metres and round two corners in my house; it’ll work much further if there is ‘clear line of sight’.3. Two bluetooth devices can be connected at once - I’ve tried it, it works.4. The unit reliably connects to its remembered devices automatically. It also starts up automatically with its last configuration - essential for use with TV’s.5. It’ll work very well with Apple Airpods though if the airpods are already paired with an iPhone/Mac, they will need to be unpaired (click ‘forget this device’ on the iPhone/Mac). Being able to work with airpods is a bit of big deal as they can be a pain, being as they are in a way, two bluetooth devices which are also pushy in their way of wanting to be paired to only one source. Apple utilise their own version of 'apx hd' and I suspect that it's compatible with Avantree's system. I say this because, in my opinion, the airpods appear to work much better than Jaybird earpods in this role.Cons1. There is no battery. This and it’s protruding antenna doesn’t help its portability.2. A battery might be of benefit when used with a laptop to smooth or clean the power supply. I’m going to try out this Avantree with a Macbook and a Lenovo Thinkpad laptop and I’ll post an update on this in a couple of weeks.OtherI’d a small hiccup registering for the extended guarantee; it’s a must-do thing within 30 days of purchase. The manufacturer’s customer service people helpfully dealt with this issue promptly. The power is led to the unit by a micro usb cable; it’s essential that this be the original cable or another high quality cable. A low quality cable used here will cause disruptions to the sound stream. This product has advanced features such as 'HD' and 'APTX'; I haven't tried these features as my other kit does not support them.
