Issue with Sennheiser aptX Low Latency Headphones
We have found that Sennheiser's HD-350BT, HD450BT, and CX350BT seem to have connectivity issues with our Trasmitter Adapters.
Common complaints include:
- Hard to reconnect
- Connects but takes a while for sound to come through
- Transmitter shows it's connected via LL but there's still significant audio lag
- Cracking noise
Our testing results have shown that the connectivity issues and the audio lag issue often disappear after a few reconnections.
Nonetheless, other customers have contacted Sennheiser about this, and Sennheiser have admitted that they have some firmware issues (further confirmed on the three headphones' Amazon reviews).
If you encounter issues mentioned above, please also contact Sennheiser's customer support and let them know.
