ESYNiC Bluetooth 3.0 Transmitter Receiver 2-in-1 Receiver Transmitter Wireless 3.5mm Audio Adapter Bluetooth Car Kit for Home Audio System

This is a very small unit that allows you to either receive or transmit a Bluetooth signal which allows you to use Bluetooth connections on older electronic devices. I had a problem connecting my phone in the receiver mode and customer service promptly replied to my question. Since the supplied directions did were not very explicit, I thought that a flashing blue light on the device indicated a connection mode. I found out from the representative that you have to hold the mode button until it alternately flashes blue and red. This is the connection mode. Once I tried this, it connected to my phone with no problem. The reviewer that could not connect to anything did not hold the mode button long enough to get the alternating blue/red lights.The instructions also do not say anything about charging the unit, but the supplied USB cable is for charging. A full charge takes about 2 hours, and then you are good to go for up to 8 hours in transmitter mode and up to 6 hours in receiving mode. This unit is very useful for using Bluetooth for older devices that don't have Bluetooth capability,. This list includes computers, TVs, headphones, etc. Although Bluetooth connections can go up to 30 feet, this is dependent on resistance elements such as walls.I received this Bluetooth transmitter/receiver at a discount or for free for my honest evaluation and review. My reviews are nothing less than honest because I rely heavily on customer reviews for my own purchases.

Very protective case. This case is very snug (good). But that also means it is a bit of a struggle to fit it on my Samsung Note 3.The edges of the case on the face side extend around the edge of the device and slightly above the glass screen to provide very good protection. All of the chrome on the device is completely enclosed.The case is made of a hard plastic. The back is completely flat. The camera edges are totally protected similarly to the screen edges. The S-pen is easily accesible.I have a bad habit of pressing the Note 3 power button when gripping my phone and locking the device. This case requires more effort to press both the power and volume buttons. I love that.

UPDATE 2/8/2017: A customer representative contacted me and offered to send me another one to test out. I received it today and it performs better than the MPOW StreamBot 2-in-1 MBT3. This product is good if you get one that works. I still believe the QC on these are sub-par, but I don't think any other company does much better either.1 star removed since my original order did not work.ORIGINAL: The one I received did not turn on, even after 24 hours of charging. Someone else had this issue before, so it might be more common than you think.

Just received my Bluetooth transmitter and I can't believe it!! It hooked up to my Sony MP3 player and ear bud right away! I have purchased a different one in the past and it didn't work so I was reluctant to try again but I gave in and am so glad I did... Thanks eSynic for making a great product and loved your email asking about my purchase...that gave me reason to believe in great customer service 😄

A very nice and compact Bluetooth transmitter/receiver. The flashing blue light is a bit too bright and the sound-volume CANNOT be controlled via the unit. Otherwise an excellent transmitter/receiver.

Very good....I wish it had a little bit of more power- higher range.... but is good enough and for the price is great! Unfortunately does not connect with Bose Mini Soundlink- bluetooth speaker

This little device is awesome!I charged it, paired it to my phone and had wireless headphones! Not sure how long the battery will last before recharge but this has a great sound.Bill Parsons

It worked just fine but the lack of instructions both in the box and on the website was a bit of a problem.I purchased two to use together, one as TX the other as RX. I had trouble pairing them at first but it turned out I simply wasn't holding down the pairing button long enough. They found each other with little problem after that.

Faut arrêter de passer de la pommade et d'en rajouter de trop quand on a eu l'article gratis en test.Quand vous dites 7/8 heures d'autonomie et même un qui dit jusqu'à 10 heures c faux ou bien l'appareil qu'on vous a donné pour tester avait une batterie très différente de celle de ceux qui sont en vente.Car celui que j'ai acheté en toute confiance en lisant vos commentaires, je le mien ne tient que 2 heures et 10 mn exactement. J'ai mis mon chrono portable pour le tester.Ce transmetteur serait très sympa s'il avait une bien meilleure autonomie. Donc je suis plutôt très déçu par son autonomie.Je pense que les testeurs abusent sur leur dire et nous induisent en erreur pour nos achats, je ou alors on leur fourni à eux du matériel bien + performant que ce qui est vendu par la suite.

fonctionne parfaitement, facile à utiliser, et très discret. Utilisé avec un casque bluetooth, c'est parfait pour la tv. Testé avec plusieurs appareils il n'y a pas de parasites, et la transmission est très bonne (essai à une trentaine de mètre).

Rien à redire, ce transmetteur récepteur marche parfaitement. Un bon produit à recommander sans hésitation pour un prix modique en plus.

Produit très bien. Derrière la TV ou sur un iPod ainsi qu'une radio. Magnifique simple a utiliser.La Connection se fais très bien.

petit mais pas mal dus tout .le son manque de dB quand on l'utilise en transmetteur mais il est de bonne qualite donc il faut posser un peu l'ampli
