## Description

Enjoy wireless audio from your TV with this Bluetooth adapter. Supports aptX Low Latency for synced visuals and audio. Works with headphones, speakers, and wired setups.

Review: Ideal for upgrading a TV or an old desktop for bluetooth sound - 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 desertcart’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 mode Bottom 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. Pros 1. 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. Cons 1. 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. Other I’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.
Review: Fantastic Bluetooth Transmitter / Receiver. - I have been looking for a unit like this for ages and it is everything I hoped for, you see I'm partially deaf and though I have Bluetooth hearing aids with a transmitter to connect to the TV, designed by the manufacturer of the aids but plugs into the earphone socket on the TV, this is great for me but nobody else can hear the TV. So the thing is as useful as a chocolate fireguard, I can't use it unless I'm alone so I need the volume quite high even with the aids so its uncomfortable listening for anyone else as I have a cinema sound system. I spoke to the manufacturer to see if something could be done, this fell on deaf ears ( pardon the pun ). Then I found this little beauty that does everything I need, I can have the Bluetooth connected to my hearing aids plus a second pair of Bluetooth headphones and a bypass to the cinema sound system all working systematically . I have full control of the volume for both Bluetooth outputs on the unit plus the bypassed sound system can be controlled from its remote, so now everyone in the house can listen in comfort. I have used the optical cable between the TV, the unit and the cinema sound system. The range of the Bluetooth is fantastic I went out to my shed which is about 20 meters away through 2 brick walls and the sound never missed a beat. The unit is well made, very neat and compact and certainly an asset to me and my family. A brilliant piece of kit that I would highly recommend if you need up to two headphones plus speakers working systematically.

## 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.

### ⭐⭐⭐⭐ Excellent device, but with a caveat
*by P***T on 27 October 2020*

Me and the Mrs are well into our music, and being as I am a bit of a tech-head, I love my gadgets, and as part of that we do actually have a very nice separates system in the living room connected to the TV. However, we also live in a semi detached house and while we think the sound proofing is quite good between the houses, a tendency for late night listening meant we wanted to look into a headphone solution. We have had such setups before. First we had a couple of pairs of headphones, the brand of which I forget now, but were basically considered entry level audiophile wired headphones out of a Behringer headamp. It worked, but wasn't the last word in refinement or sound quality. This was then followed by a Sennheiser RS 160 setup, this was an RF wireless setup. Again, it was decent but not mind blowing. Both solutions felt like a noticeable step down in quality from our separates. Eventually we just gave up on the idea for a while, but we had a few choice discussions about the volume levels, and so it became obvious I would have to re-visit the idea. I already had a nice pair of B&W bluetooth headphones (P7W), and I adore those, so logically, I thought get a transmitter like this and another pair of headphones. My research led me to the Avantree. Sennheiser do a similar device but the reviews were lukewarm and the suggestion that using 2 pairs would default to SBC codec were somewhat off-putting. I bought this and a pair of newer B&W headphones for the Mrs. The newer pair, the PX7 are significantly different to the P7, with the latter being like old-school wireless headphones and the newer pair being crammed full of noise cancelling tech and using newer AptX HD / Adaptive codec. Unfortunately, I think it was these differences that resulted in it not really working properly, when we played both the P7 and PX7 simultaneously, we experienced stuttering sound in the latter, newer headphone. I could not get to the bottom of this, however, I had a feeling that because the older headphones worked perfectly, then it was probably the mismatch causing the issue. Not just that, but the PX7's didn't sound as good and were less comfortable, and we didn't need the noise cancelling tech (disabling it made little difference to the quality), so I decided to try and sell those and find a matching pair of P7s. I'm glad I did, as they now both play flawlessly on the unit with excellent sound quality and minimal levels of latency, and both max out at their native AptX codec. The device itself is easy to set up and has clear instructions, I'm impressed with the thought that went into it. I like the way it talks to you to tell you whats going on as well. I would have given this 5-stars but I have to knock off a star for this stuttering issue. It seems to me like you will definitely get the best results if both pairs of headphones are matched. It's not guaranteed that you will have an issue with different types of headphones, but your mileage may vary.
