Bluetooth 5.0 Transmitter Receiver, BOIROS 2-in-1 Wireless Audio Adapter for TV Headphones Speakers PC & Car Stereo System, 3.5mm AUX, Advanced decoding HD, Low Latency with Indicator Display

It's easy to set up and comes with an assortment of connecting cables including optical and, it pairs quickly and shows the connected codec. As it uses Bluetooth 5, it may pair using the basic SBC codec instead of AAC if it cannot connect with AptX, LL or HD. The SBC Codec does have a latency issue as well as poorer quality sound. My cheap Philips headphones paired to aptX almost immediately and, although it wasn't Low Latency, lip sync (latency) with prople talking on television was virtually undetectable. Predicably the aptX connection provided good quality sound. Update 3 August 2020 I bought a second BOIROS transmitter receiver and paired it with the first. Both paired in HD, great sound and no latency issues with the television. I had used the optical connection between the television and the first BOIROS, with my headphones wired from the second Boiros: that was loud and great quality. As the AKG and SONY headphones don't have integral volume controls, I changed the input to the first BOIROS to the headphone output on the television so I could adjust the volume. Slightly less bass but still clear speech without a latency (lipsync) issue. Brilliant purchase that solved my slight hearing loss coupled with the usual poor sound quality from the speakers in a flat screen television. A pair of BOIROS units - one set to transmit and the other to receive - are highly recommended with wired headphones.

I bought this device for use in car as I didn't have Bluetooth connection only aux in. It works great but beware that when it's charging it picks up static like an fm transmitter or worse, I could hear the revs of the engine in a bad buzzing noise coming from the speakers over the music but as soon as I disconnected the charger it went perfectly quiet so although you can use it while charging, the quality of the sound drops fenomenally. Aside from that really good device, battery holds and sound quality is perfect(when not charging)

I wanted to use my Sony WH-1000XM3 bluetooth headphones with my non bluetooth TV and HUMAX pvr. I plug the optical out of the Humax into the input of the transmitter, which then connects to the Sony headphones. There was a big lip sync delay at first, but that is because I have an 80ms delay on my Humax to sync with my TV. If I set the delay to 0ms the sync is acceptably close; not perfect but fine as far as I'm concerned. However, the big bonus for me was the realisation that the device can be set to receive. This means that I can connect it to my non bluetooth hifi (Marantz CR603) via its aux in. Bingo, two devices updated to Bluetooth! Very easy to set up and use. This is how technology should work.

I got an e-mail from the seller after my purchase offering help if I had a problem. This was my problem: I bought this transmitter/receiver mainly to connect my Sony WH-1000XM2 Bluetooth headphones to my TV via optical output/input (in picture: Samsung TV Evolution Kit). My headphones has Bluetooth V4.1.1 and supports the following sound formats: SBC, AAC, APTX, APTX HD, LDAC. I thought this BOIROS transmitter/receiver would be the perfect fit, because of all its supporting sound formats: A2DP, AVRCP, SBC, AAC, Fast Stream, APTX, APTX Low Latency, APTX-HD. I am having trouble connecting in transmitter mode. The TX light only flashes without ever connecting to anything I own, see the list below: - Sony WH-1000XM2 = Bluetooth® Version V4.1.1 - JayBirds = Bluetooth® Version V2.1 + EDR - Bose Portable Home Player = Bluetooth® Version V4.2 Please help me understand what to do? The seller answered quickly, got me the right help, and now I am a happy customer of this excellent product. I think it is rare to have such a good product in addition to such good customer support. A rating of five stars is fully deserved.

The product may be suitable for music transmission, the optic conversion to Bluetooth does work and the item is compact and easy to operate -- that said there were major sync issues for me when attempting to use for Bluetooth sound transmission from my TV - sound would also drop out altogether when at low levels, and a slight pop would be heard as it came back on - it would also not connect with some of my Bluetooth headphones. Have decided to invest in a new TV with Bluetooth built in, as I have had other transmitters and sync issues were a problem with them also - so this is not an uncommon problem.

Easy to set up. Batteries last a long time and unit works when it is charging. Very occasionally there are instances where there is momentary interference and signal loss. Using the unit with the TV there is a noticeable delay between picture and sound, so it can not be recommended for use with TV shows, films etc. Transmitted sound quality is very good, open and clear, it seems less compressed than other Bluetooth transmitters. Recommended for music and audio/ radio media, not recommended for video where sound transmission must be in unison with picture - playing YouTube music videos the delay is not a problem for me as the sound quality is excellent.

Pros - Easy set up, easy connect,/pairing, great displaying of connection - instantly see if connected in Low Latency mode, No lip sync issues watching TV. Cons - At low sound levels, nothing is sent to headphones so you get completely silent gaps rather than the low level background noise. This is amazingly annoying. You don't miss any talking but silent gaps ruins the experience. Verdict - probably great for music, but as I bought it for TV the sound dropping out makes it pretty annoying. As sound is the main reason for buying them I have to give a 1 star rating.
