Sennheiser BT T100 Bluetooth® Audio Transmitter (Renewed)

I used this to be able and hear audio through a wireless headset and till be able to use goXLR and an XLR microphone. Without this adapter, your pretty much stuck with wired headphones.

This was exactly what I needed. Had an older projector with a 3.5mm audio out...but have new school speakers with Bluetooth. Was running wires before creating a tripping hazard. Got the transmitter connected to the speakers in a matter of minutes and don't have to deal with batteries because this can be powered from the projector USB. Will update review if anything becomes annoying but I've already power cycled the system and it remembered and just auto connects now.(Update after multiple uses still top notch only thing is the overall volume seems to have a drop compared to running a headphone wire, but my way too big speakers were on 1-2% before so no issue on my end to turn it up a bit...still only have them at maybe 10%...(these %ages were not scientifically tested lol volume drop could just be in my head due to different game/stream service🤣))

I bought this because I heard that the main weakness of the Sennheiser Momentum 4 was the awful pairing process. I figured that getting a Sennheiser transmitter would make pairing a breeze, but boy was I wrong.If this box is ever manually powered off, it has extreme difficulty pairing with the Sennheiser Momentum 4, even if the two were previously paired before shutdown.As a sanity check, I tried pairing my headphones with my phone, and it successfully connected within seconds. I powered off my phone, then tried connecting the headphones to this box again, and it took another ten minutes or so before it finally connected.I've heard "Connected.... No Connection!" over thirty times in a row while using this thing.Other than that, it's been fine. I like how it accepts both aux cable and optical. That's a pretty rare input selection for wireless transmitters.Sound quality is as what you would expect from Sennheiser - phenomenal. It rivals the sound quality from my wired headphones from AKG, though your mileage will vary based on your particular setup.

I have been unable to use this product because it changes the pitch and fidelity of the music source considerably. I am using an iMac with Monterey OS. Headphone jack out. The Sennheiser receiver is going into a normal Integra receiver via HDMI cable. The distance is about 9 feet with no obstructions. As a music professional, this is surprising as Sennheiser has a good reputation in the industry.

I bought this to allow me to continue watching TV in bed once my wife decides to goto sleep. The audio is very clear and unlike some Bluetooth items, it easily will connect to my Sennheiser headphones by simply placing them on my head. I love the simplicity of the connection and the audio quality is amazing. It’s just so natural and effortless.

Perhaps this would work for one headset, but with two we found that the headsets would alternate losing connection while the movie was playing, and worse they kept getting unpaired. I’d no sooner fix one headset connection, then the other would drop. It seems the device isn’t powerful enough to stream to two headsets, despite how it’s advertised. Worked great with one headset though.

I needed a low latency wireless headphone system to listen to the sound from videos (movies, etc.) while simultaneously having the speakers on. To make that work, you need extremely low latency in the bluetooth wireless system. Apparently the only viable solutions use the Aptx-LL (low latency) audio codec over bluetooth.After reading a bunch of reviews, I decide the Sennheiser HD 350BT headphones were the obvious choice for sound quality, product build and comfort. https://smile.amazon.com/gp/product/B083WS3WPK/. They are very good.Initially I bought a bluetooth transmitter from another manufacturer (not Sennheiser), which supports Aptx-LL. You'd think that all bluetooth transmitters with Aptx-LL support would work with all headphones with the same standards, but that is only partially true. With that first transmitter, sometimes it would work rather well, sometimes the sound quality was bad (crackling noises), sometimes it was hard to connect to the phones, and sometimes the latency was EXTREMELY high, implying something was malfunctioning.The Sennheiser transmitter works great. Excellent sound quality, reliable connections, and extremely low latency. Worth the extra money.

Functionally, this item works. Eventually. Pairing was extremely frustrating. I got it to work but the volume is so reduced that I have to increase the volume on my receiver to almost double what the normal volume setting would be. Overall, I am not very happy with this product.
