Phoenix Hi-Fi Bluetooth BT5.0 Audio Receiver & Transmitter with aptX HD, Low Latency, aptX, Qualcomm CSR8675, 3.5mm AUX/Optical/SPDIF/RCA. for Home-Theater, TV, Speakers, Mobiles

The product does what it says, amazing sound quality when unplugged from charger, while plugged hissing sound comes, but it is already written as warning in notes, Bluetooth connectivity range is the best thing about this. The device works with all kinds of headphones, I tested with Sony XB900N which is very hard to pair, finally had to open manual of both device and headphones to figure out proper way of pairing.. This is only required once as device pairing is kept in memory which is just amazing. Overall best product 10/10 One plus bullets wireless pair easily with no hassle. Be sure to know if your Bluetooth device is compatible with this transmitter before buying if you are going to use it as transmitter. Reciver is very good and works great with all devices.

Tested this using a Denon amp (Optical), Edifier 2.1 multimedia speakers and Marshall Major III wired headphones (aux), with Nokia 7.1 & Mi A3. Sound: Great quality, with good clarity over all frequencies. I feel the bass is slightly amped up, which isn't a bad thing. I got better sound through this than through my headphones plugged in directly into the phone's aux. Output is quite loud. Bluetooth: While Aptx and AptxHD work great, LDAC is not supported. But I doubt you will notice a difference unless you are using extremely high end equipment. Pairing is easy and connection is reliable. Range, on the other hand, is not great. It will cover an average hall, but is quite prone to interferences like walls and bookshelves. Build/Design: Looks nice, with a (literal) silver lining. But I would be careful not to drop it because it is light plastic. Lack of a clip is extremely disappointing, because I still need to use a long wire and my pockets when using headphones. The size of this device is small enough to be clipped on to the headphones or clothing, so I am surprised they didn't allow this feature. The FiiO devices have better build quality and clips, but cost twice as much for aptxHD. Other: Good packaging and detailed user manual. They have provided RCA-Aux, Aux, SPDIF and USB cables so you are good to go in whatever circumstances, without the need to buy any cables or converters. Cables are average quality, and not gold plated, AFAIK and I am using my existing gold plated Belkin cables instead. This is a great device with excellent sound and many connectivity options, but the lack of a clip to attach to headphones or clothes is severely disappointing.

An excellent BT reciever/transmitter which gets connected very fast, streams music without loss of quality and is versatile in all aspects. The power on press button also works for pausing music. Battery life remains to be tested. Optical out needs a slight volume boost when connected to Onkyo TX NR 515 from mobile phone. This gets resolved after the volume is jacked. Yet to try its performance as a transmitter. Works either as a receiver or transmitter which can be toggled. There is also a toggle button for Aux and Optical/SPIDF interface. Very compact and sleek device with superb functionality. Also felt it boosted the volume to some extent. I maybe wrong. Altogether a wonderful piece of work.

I bought this product a month ago and was able to use it only now. Bluetooth connectivity to my phone is okay but I cant connect to my TV ,home theater or even pc with the cables provided. I tried with the AV connector then with the provided USB cable and also the optical cable. There is no connection established between this device and any of the above, it just does not register. Really dissapointed. I do not have an option now to return on Amazon as its been a month. I suppose you have to take a chance buying such a product as its made in China and it may or may not work.

The device is good. No lags in sound. I use it with my Akai TV set which has firetv stick attached to it. Also, i use it with my desktop and laptop. No delays of any sort. Connection was made quickly. And hassel free. It is made in china. They should find a vendor to make it in India. Because of their manufacturing origin I am giving them 3 stars.

I purchased this after my Logitech Bluetooth adapter got fried after a few years of usage. I wasn't sure if this was the best and reading some of the reviews here I made this purchase. They provide the female to male 3.5mm converter, a male to rca (red, white) cable, toslink cable and the charging cable all in the box. The build of the product and the cables are good quality. When I fired it up I was using this as a receiver and the audio is boosted, I mean it crisp and the bass and treble are spot on, so are the vocals after tuning it with an equalizer. I also tried the transmitter mode and it works perfectly.

Product has good Battary and Bluetooth connectivity. But seems like there is lot of latency. I connected two of these devices one as Trans and other Receiver to make my subwoofer as wireless. But the quality of sound was not up to my expectation. There was a visible time lag on both ends hence my purpose was not served.
