TROND Bluetooth Transmitter Receiver V5.0, Bluetooth Audio Transmitter, 2-in-1 Bluetooth Adapter for TV/Car/PC/ MP3/ Headphones/Home Stereo/Speaker, AptX Low Latency, Pairs 2 Devices Simultaneously

3rd update Mar 20, 2019:Updating my previous, original 2-star rating to 5 stars thanks to their support given and a fully functional replacement device in ~2 weeks.--- TL;DR ---My initial experience from Sep 2018 with my DUO was mixed. I didn't contacted support, and wrote my first “quick review” on Dec 2018 or Jan 2019. On Feb 2019 I got contacted by a person from support because my review.Since then, the support person 'greatly explained' the causes of the issue and guided through the process for getting a warranty device.I'm very placed with the detailed support given by him, and new replacement device works great!--- Device ---My issue from Sep 2018 while RX mode was indeed a defect on some units on the Amazon warehouse from that period, which occurred in any codec (SBC, aptX and aptX LL).The TX “issue” of audio fading/cutting on low volume (e.g. while playing on Nintendo Switch on low noise scenes), is normal. One must turn all the volume up on the audio source so the device can capture it, as the chip isn’t an amplifier but just a transmitter.Due the RX issue, I was offered replacement device. Decided to try and upgrade to the Trond DUO S. Now I can confirm the intended correct functionality of RX/TX on both devices (DUO and DUO S), and confirmed the RX firmware defect.Additionally, I could test pairing a DUO with a DUO S. They work amazing on aptX LL (Low Latency) which is selected automatically as it’s the best codec available on both. You can easily see and hear the difference between the standard SBC and aptX LL, the latter feeling instantaneous on audio visual feedbacks.After 5 months of use and having a fully functional unit...Re-viewed PROS:- Compact goodness.- Good battery duration, easy charging, and can be left connected.- Easy pairing, even multiple pairing (after you get the “trick” for pairing).- Lot of adapters included.- Long satisfaction warranty (18 months) and great support service.Re-viewed CONS:- No configurable low-battery audio signal. It can confuse you from phone alerts, etc.- No configurable LED.--- Support and warranty ---They are serious on their support area, as they followed me up some time latter from my original 2 stars Amazon review on all my emails until I got the issue solved (on my case a warranty applied, until I had it on my hands, even though it would need a global shipment).They DO respect their “18-MONTH TROND warranty” additionally from the Amazon return period, so you can buy with confidence that any defect will be followed quickly and in great detail. This was getting replied the next day and getting detailed explanations of the cause(s) of my issue along with the possible actions to take.Big thumbs up for Trond. They managed to stand up with the pesky support processes of many other bigger companies out there.--- MISC ---My only complaint could be their webpage. Before making my original purchase, I looked up their website and it feels empty and outdated, like if they didn’t exist nor could give any kind of quality support in case you got into issues. They deserve a newer and better site that shows and highlights their great client support.-------------------------------2nd update Feb 22, 2019:Their customer service contacted me regarding the issues I mentioned here, trying to help me with them by proposing a replacement thanks the 18-month warranty.I will try keep updating this review accordingly.------------------------1st Original review:Has been some time that I got this (Sep. 2018) and have been postponing a quick review, some thoughts on this device.I have used a few times on various scenarios (playing on Nintendo Switch, video watching, etc., with different headphones as receivers, and different controlled sources as high end phones and laptops).Personal cons:- 1 issue as a receiver.The device is identified as apt-X on my phones, but the output audio is awful, sounds muffled, as phone call quality on all devices that I tried.This reaches the point that the Windows 10 "bells sound" sound test gets very pitchy and gets highly distorted and the very end of the last bells. I would like to provide an example of this by recording the output from the Trond when used as receiver.- 1 issue when transmitting.When transmitting, the quality is pretty good, BUT, when having low volume sounds coming from the audio source, the Trond seems to "fade" or cut-out the audio.Playing games on the Nintendo Switch is not enjoyable with some games that have some low-volume scenes, since those are intermittently faded or cutted-out. There is no noticeable delay at least from what I can tell (but at this point I just stopped using the Trond both as receiver and transmitter).(As I said, the quality is great when transmitting, but not sure if it's real aptX quality grade, my headphones don't have any indicators of what protocol is being used when receiving audio from the Trond when it's transmitting, neither Windows helps with this).Pros:- Super compact, portable.- Portable power of ~6 hrs or more.- Quicker setup as receiver.- Can be used always connectedNote that I probably got a defective device but.... Anyways, I stopped using it since then (Sep. 2018). It has just a couple of days of usage. Recently I got the time use it again but as a background music receiver, as the previously mentioned issues are just annoying.The receiver sound quality is the dealbreaker for me.Maybe is normal for the price, just the aptX is there for the short delay feature of the protocol.

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.

This is easy to use and works well. My only frustration is that there's no low charge warning/indicator. It just suddenly stops working. Would be nice to get a heads up!

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.
