CUBETEK 2 in 1 Bluetooth V5.0 Transmitter and Receiver 3.5mm Adapter; for TV; PC; iPod; PSP; PlayStation; Stereo; Support aptX Low Latency for Home and Car Audio System. Model: CB-BTI-018

I used this on powered speaker and felt a slight difference in audio quality although negligible but on powered amplifier it worked flawlessly. Quite easy to use and more than sufficient blutooth coverage. RX/TX both support aptx hd audio. I tried this on DAC too in RX and TX mode and both receive aptx hd audio. In my opinion Sound quality - 4/5 Battery life - 4/5 Bluetooth Distance - 5/5 Ease of use - 5/5 Quality - 5/5 If you are willing to buy a blutooth receiver /transmitter then look no further as I'hv used logitech, pagaria, crossbeats and tewtross but this one is definitely stand out from crowd.

Nice product working perfectly, but only one connection at a time.

Thanks to Amazon/ Seller for timely delivery and good packing. I've been using this device for about 2+ weeks now on a regular basis and it's made my listening to music a much more convenient process. The connectivity part is very easy by following the steps in the instructions booklet. I've paired upto 4 devices in Receiving mode and 2 in transmission mode seamlessly. The sound quality in both modes is very good. If you're not using Spotify premium the sound quality/volume will be a bit less, but other downloaded mp3s etc. Play perfectly with good audio quality. There's a minor (1sec) lag while playing/pausin/forwarding track's but it's not a big deal. The range of the device is very good, I've used it in both tx/rx mode with atleast 2 devices connected at more than 25ft and faced no problems or drop in sound quality, even in different room. ( Yes if you try between 2-3 walls it will drop sound/connection just like any other device!) Battery is superb, I've been using it almost ever other day for about 2-3 hours in a day and it still has juice left. One of the major cons of this device is that it deletes all paired devices from its memory every time you switch modes(tx/rx), so you have to pair devices again. It's a major setback specially if you are regularly going to switch modes. I use it mostly on rx mode and sometimes avoid using in tx mode if I know it's going to be used for just a while to avoid the whole pairing process. The cables provided are a bit short. Overall I'm happy with the device and it's performance. Only reason why I gave it 4 stars was because of the re-pairing process.. I would still recommend this device!! PROS Product quality good Easily pairs V. Good sound quality V. Good battery V. Good range No connection drops CONS Short cables Have to re-pair devices after switching modes

It's sleek, easy to install, and has good battery life. But there is a lag in the sound, you will hear 2 different sounds if both TV and Home theater speakers are on. The sync is not the best. Overall good and worth for the money.

Excellent product, good bank for the buck. Easy solution to instantly transform any old set of speakers into great bluetooth 5.0 audiable speakers, works reverse as well. Transforms and non bluetooth TV to bluetooth and let's you wirelessly connect to bluetooth headphones.. good for night time bing watching your fav Netflix and prime movies. Easy to use and setup. All accessories comes with the device. Excellent battery life of 6 hrs, more than sufficient. Excellent range of 30 feet roughly in direct line of sight. Highly recommend this product if your looking for an easy solution.

I bought this after checking the compatibly of using this product with two Bluetooth headset simultaneously and it's was mentioned in the description that can be used with two headphones together. Also reviews mentioned the same. However my experience is really bad, as while using two headphones simultaneously one out of the two gets dropped after 15 minutes of connecting. This happens continuosly with one or the other and you need to switch off and switch on to reconnect headphones. The seller was so courteous to connect with me when I place the request for replacement, however problem was not resolved. So finally had to replace the product, but that also couldn't help and same problem persists. Will try for another two or three days and if still same problem exits, then finally need to return the product.

Small, compact and cute... Circular shape is a little smaller than Google ChromeCast 2, larger than Tantra Fluke Bluetooth Car Audio System (I have these hence could compare the size). Worked like a charm when I attached it to my Creative 2.1 speakers and paired with my phone (Cubetek setting to RX). No perceptible issues with sound quality. Pairing was easy since you can see the device on your phone available for pairing. Also used this with my iPod Classic 160 without any isseus as well, although here I had to make sure (as commented by others in this forum as well as in the reference manual) to turn off other bluetooth devices in the vicinity other than the one I intend to pair Cubetek with (used to pair my JBL over ear headphones)... Paired easily (I used TX setting here). Again, no compromise on the sound quality within my 1400 sft apartment. I have been using Cubetek with one single charge for a week now (I understand I am not an avid listener but at least an hour a day for 7 days... Without charging) so the battery life is also decent. This device, when attached to any non bluetooth device, hangs exactly like a Google ChromeCast 2. While travelling, the design could be a put off though since it hangs (attached to iPod Classic 160). I saw one similar device in Amazon UK designed specifically for iPods that connects through a 30 pin jack and is rectangle in shape but quite expensive in INR value)... But I am happy with Cubetek because I can use it on any device that has a standard headphone jack (the one comes with all mobile phones nowadays). Very satisfied with the purchase...Thank you Amazon as well as Cubetek for bringing this to me. Serves my purpose 100%!! I will update my review in 6 months time for a long term usage experience.
