TROND Bluetooth 5.2 Transmitter Receiver, 2 in 1 Bluetooth Adapter for TV to Airpods or Wireless Headphones, Low Latency, 3.5mm Transmitter Audio Adapter for Airplane Gym Equipment Home Stereo

I have been hunting down a low latency headset/transmitter combo for a while, as many others here. The hunt can get tricky because you have to pair the two devices that will agree to talk in low latency mode. So I took my quest rather seriously and I bought a bunch of headsets and transmitters.For reference, I call "slow" connections to those where you can see your video out of sync with your audio. 90 milliseconds or more in delay will do that. Similarly I call "fast" connections where audio and video are reasonably close or in sync, with the delay being 30 milliseconds or less.In my experience, AptX is a slow codec and the improved AptX-LL is fast.So then, any device that does not explicitly say AptX-LL or Low Latency will work slow; a device that only says "AptX" is not enough. And the wireless connection can only go as fast as the slower paired component so having either a slow headset or transmitter will make your sync slow.To make things more interesting, not every headset that does say AptX-LL will use low latency technology with every transmitter out there. You kinda have to mix and match. So for example a given transmitter will connect fast with a certain headset, but slow with some other brand. And it will do so consistently.Not so the TROND 2-in-1, however. Every headset I tried with this little device worked fast. The headsets include: Premium MS301 Mixcder Wireless & Wired V4.2 Bass Noise Isolation Headphones with aptX Low Latency Audio- Headset with Mic & Bluetooth - Sturdy Foldable - Universal Compatibility for iPhone Tablet PC Avantree Wireless Bluetooth Over Ear Headphones with Mic, LOW LATENCY Fast Audio aptX Headset for Gaming TV PC, 40h Battery Sound - Audition Pro [2 Years Warranty ] Miccus Wireless Bluetooth v4.2 Over Ear Headphones with Mic, aptX Headset Low Latency for Gaming, TV, iPhone, Beats, Foldable - 20h Battery (SR-71 Stealth) I tried other headsets, but those were not advertised as Low Latency and thus worked slow. Some notable headphones brands are falling behind the low latency race, surprisingly.Do not fret however, because you can still buy two of these devices, use one as transmitter and one as receiver, and just use your favorite wired headphones. Yes, low latency works quite well that way.You can pair two low latency headsets at the same time, but the low latency feature is disabled that way. It is the same on every low latency transmitter I have put my hands on. So if you are planning to do that, you can opt for cheaper, slower headsets.Aside from latency, these devices are well constructed, simple to use and most important of all, light and small. Single button operation; nice red and blue LED leaves nothing to guess. It behaves like any other standard BT device, nice and simple. It almost needs no instructions to set up. The fact that they are transmitter and receiver in the same package only adds to the versatility of this design.All in all, great little device. I do recommend it for your audio/video needs when paired with a compatible LL headset or other TROND 2-in-1.

It comes with alternate connections and the second one worked!!! I am so happy!! It was easy and now my father can hear the tv without blasting the neighbors away!! Thank you! I am ordering another one for my husband!😆😬👍🏻

These things are neat. They are very compact and light, with a generous battery life and a pretty good range. They also come with a USB cable for charging and a double-ended audio cable for physically connecting them in transmit-mode. Initial pairing with devices involves a bit of jiggery-pokery (pro-tip: make sure all your receivers are active and sniffing for Bluetooth before you power up the transmitter), but once that's done, they work pretty darn well. I own two of them (one to transmit, one to receive) and have no regrets.However, I do have two complaints:1) They add their own noises to the signal to tell you stuff like "I am active", "I am connected", "battery is low". These noises are, to put it mildly, obnoxiously loud. My mom complained about it when we were using them to stream audio to her headphones, and now that I have them hooked into my sound system, I see why - I just about had a heart attack the first time the receiver blared out the "I am connected" beep, and whenever it runs low on battery, it gently notifies me by emitting the loudest g**d**n sound that can physically exist in our universe, and it keeps doing that every five seconds until you either turn it off or your speakers blow out. Don't try plugging it in to silence it - it will keep on complaining the whole time it is recharging, despite the fact that it will happily run off a DC adapter at all other times. This is an audio relay, guys, not a smoke alarm or a nuclear reactor safety sensor - the deafening, repetitive tones are bit excessive.2) I cannot get them to pair with my phone. I bought two, hoping one could connect to the phone in Rx mode. If that'd worked, I'd have used the double-ended cable to hook it to the other unit, that one set in Tx mode. Then I'd have been able to send my phone's audio signal wirelessly to two Bluetooth headphone sets, which is what I wanted. That way, me and my mom could listen to the phone without disturbing others. No joy - set the phone and device in seek-mode several times but could not get them to acknowledge each other. This probably won't affect you, unless you a) have an older phone like mine where the physical audio port is all jacked up from years of being janked when the wire caught on something, or b) got suckered into buying some sort of weird, hypothetical phone that, say, has no headphone jack because its makers hate their customers...hypothetically ;)

FUNCIONA PERECTAMENTE

Es muy bueno , funciona de maravilla y si trabaja bien entregando sonido estereofonico , funciona mejor que el anterior que compre

Meine Frau brachte mich auf den Gedanken, dass über Kopfhörer die Tonqualität erheblich besser ist. Sie benutzte schon seit längerem einen Kopfhörer aus gesundheitlichen Gründen. So startete ich einen Versuch mit dem Transmitter, der auch sehr schnell geliefert wurde. Unsere Kopfhörer sind im Preissegment von 38,- Euro bis 48,- Euro angesiedelt und neueren Datums. Nachdem ich den Transmitter so angeschlossen habe wie in der Beschreibung angegeben und den kleinen Schalter von RX auf TX umgeschaltet hatte, versuchten wir die Kopplung so wie in der Beschreibung. Es klappte sofort. Ich war begeistert. Beim 2. und 3. Mal klappte es dann nicht mehr. Mir war klar, da gibt es einen Trick. Der Transmitter speichert wahrscheinlich die Bluetooth-Verbindung und erkennt die Kopfhörer automatisch. Nun braucht man ihn nur noch einzuschalten (Schalter ca. 4-5 Sekunden gedrückt halten) und dann den ersten Kopfhörer einschalten in in einen Abstand von ca. 10 cm zum Transmitter bringen. Dieser beginnt nun selbständig hektisch rot-blau zu blinken und kurz danach kommt die Ansage ich verbinde auf englisch. Nun legt man den Kopfhörer aus den Kopplungsbereich ca. 3-5 Meter entfernt hin und nimmt den 2. Kopfhörer und wiederholt den Prozess. Auch hier erfolgt die automatische Erkennung nach wenigen Sekunden. Sollte es mal nicht klappen den Kopfhörer abschalten 3 Sekunden warten und den Vorgang wiederholen im Bereich von 10 cm. In 4 Wochen gab es kein einziges Mal wo mehr als 2 Versuche nötig waren. Die Tonqualität ist super und es gibt auch keine Sprachverzögerung. Ich habe deshalb gleich einen 2. Transmitter gekauft, da der Markt sich schnell verändert. Was heute gut ist, kann es morgen schon nicht mehr geben. Also volle 5 Punkte.

Falta un manual que detalli totes les possibilitats.

Gekocht om met koptelefoon op in slaapkamer (16m2) tv te kijken, maar afstand (+/- 4,5m) is te groot. Geluid hapert en stopt.
