Bluetooth Audio Transmitter Receiver Connector Adapter Device for TV Pc Music System | V5.2 | Compatible With Aptx Aptx HD Aptx Adaptive Aptx Low Latency devices with Aux 3.5mm Jack RCA Port

Good product, working fine

Its a good and must have device, works really well to enable wired devices for wireless connectivity. Bluetooth connectivity is fast as it connects with in 3 seconds. Sound quality is great as it supports LL and aptx codecs. I have tested Musesonic's sound quality with various devices such as Desktop PC, Mobile phone, hires audio players etc.. The battery life of this device is also promising as it runs for 18 hours constantly. Form factor is small but functional buttons are a bit rigid that doesn't feel premium. The conclusion is, Musesonic is overall a great device in its price segment.

I needed a device to connect my Google Home to my Onkyo 7.1 HT. My Requirements: 1)Interface to HT using optical cable 2) Best sound quality 3) TX and Rx options. 4) Unit in operation even when charging.(if battery goes bad after some years, I should still be able to use it.) After extensive reading of the specs and reviews on Amazon, I decided to buy this. Pros: Tested RX only. 1)Good quality, easy connectivity with Google Home, 2)works while charging. I am not hearing any noticeable noise from the speaker while charging. More test will follow during quieter times. 3) Sound quality is awesome. 4) Bandwidth: audible for me from 20Hz to ~14KHz. The unit may be reproducing above 14Khz also, but my ears may not be good enough. Tested using Sine wave. Not tested: 1)TX section is not yet tested. 2)Battery life Edit: On further testing, I hear clicks before a high impulse sound. Not so audible, but definitely can be heard when listening in quiet rooms. Reducing the rating to 4 star. Edit: On further testing, I identified the clicks noise may have been due to the connection through the Google Home and the Chromecast requiring higher processing speed. When directly connected through Bluetooth, there are no clicks. So the device as such is performing well. Back to 5 Star Edit: Checked the transmitter section. There is delay in the sound of almost quarter to half a second. Sound quality is same as receiver. Edit: Bought the device on 18 May 2020. Now on 13 May 2021, the optical output section is NOT WORKING. I do not see the red laser light in the SPDIF connector. I wrote an email on15th May 2021, got a reply 30mins later mentioning that I will receive a call from support. I received a call at 4:45pm on the same day. After discussion, I found that the two SPDIF cable have been swapped on the unit. This might have happened when we were cleaning the TV unit a few days back. Now happy to infor that everything is back to working condition. I appreciate the support team for quick response. My rating is now 5stars.

I have to edit my review yet again. This was my review a week ago : " I have to edit my review. I have been using this for about two weeks now. It was quite good at the initial stage. However, the impression is gone. I use it to watch movies at night for about 2 hrs approx. The battery now lasts barely 30 minutes. It has become useless after barely a fortnight. I gave it a five star. I now have to give a single star. It does'nt even deserve one." ... Soon after I posted my review, I immediately got an email from the sellers. They gave me instructions following which my problem got rectified. I am very impressed by the impeccable professionalism of the sellers in their manner of handling problems and issues. ... For potential buyers of the product, I think it is proper that I share the issue that I have had. When I connect the device to a charger, a red light glows suppossedly indicating charge. After about half and hour, the red light goes away which made me believe that the device is fully charged. This was my mistake and I am sure many of you would think so too. But, the red light out does not necessarily mean that the device is fully charged. Just continue charging till the charging time comes to around 2 hours. After that, you are good to go for at least 5-7 hours without another recharge. ... And I am telling you, the seller does a good follow-up in case of complaints. I have to give 5 stars. This was my review when I got the product - "Got it today, delivered one week before ETA. Simple to operate. Does what it says. Battery seems to be good (although I have been using it only for about two hours. Let's see how it goes later on.) Seems to be a nice product. Price though is a bit on the higher side, I guess." ...

I am writing this review after 23 months, bought it on May, 2019. It worked flawlessly, I could connect two bluetooth headsets and since I purchased them carefully there were no lip-sync issue and we enjoyed in TV viewing. as on 15th April, 2021 It stopped responding couple of days back. Initially I thought battery issue, charged completely, but later found it is the power button which has gone all wrong, it has stopped responding completely though it has full charge, I tried to connect Muesonic but in their website they have carefully not written their contact id/no....the result is it is basically now a dead piece and I have to buy another one. The bottom line is these are sold without any support and its basically use and throw product. Moreover, I doubt "1 year warranty" is also a farce, whom to contact?? such a shoddy business practice, customers are at the receiving end Again there in nothing wrong with the product, it is very good, but the there is no after sales support which makes it extremely risky to buy

My review and opinion is based on two days usage. No comparison with any other similar device as this is my first device of this kind. Tested for different connectivity features, range and audio quality. I have used stock as well as better/high quality cables. However, at this point I cannot comment on Product durability and how much the charge last in real usage. I have mainly bought this product for the sole purpose of connecting it to “Amazon Firestick” in RX/Receiving mode and using this to power my “wired headphones” through the “Aux out”. For this purpose, it is good but sound is slightly harsh, not very refined. Solves the purpose as dialogues and movie/series music is clear but not graceful in presentation for songs & music listening. When in this same mode the input is given to an “External Integrated amplifier” the audio output is subdued, not dynamic at all. However, I feel if the input to this BT device is through “SPDIF Digital optic cable” the sound will be much better. There is a musesonic model in the range above this that has digital optic input and output and that model will suit the purpose of those who wants to use this as an interface in RX mode. Sound will be much better, dynamic and clear. Testing in TX /Transmitting mode (Same tracks played in all options). Although this will not be my primary usage but to check the audio quality, I tested it with different components. Opt 1- Android mobile connected to this BT device with help of Aux cable and a BT headset paired with this device. Sounds OK but not as clear and refined as when the connection is done between Mobile and BT headphone directly. I also connected this same way with an external BT speaker, the result is same as felt with BT headphones. The BT range is good as I have checked by going to other rooms of my home and there is no loss of connection. Opt 2 – Connected a “WD Media Hub” to this device in TX mode. RCA analog out from the Media hub and connecting to the Aux in of the device. Tested both BT headset and speaker in this type of connection. There was lot of distortion in sound, vocals and music all getting jumbled up giving a very bad feeling. However, to reconfirm that there is nothing wrong with the media Hub I gave the RCA analog direct connection to the Integrated amplifier and everything was Ok. Sound & music was detailed, clear and dynamic. Maybe there were some compatibility issues between this device and Live media hub as there is a cooling Fan inside the Media Hub that might be creating a problem. Note - I did not test this same method of TX mode connection between the TV and the device but hope that will have somehow similar “Bleak/low level” audio output as felt with other type of components in both RX & TX modes. My final conclusion - It solves the purpose but if a person is looking for clarity and perfection in music listening this is not a proper device, it is convenient and will be decent enough if one is not looking for a Refined & dynamic performance. Ease of connection and installation, no problem faced. The price and performance are in proportion. Deserved only 2.5 stars. I could have rated this better if audio output was better.

Good quality product

Easy to use. Sound output quality improved.
