Syllable Announces D900 Headphones With Great Bluetooth Range

Syllable is a headphone maker based in Shenzhen, China. It makes various Bluetooth headphones, but these are the first it was seen with no wires at all. Syllable says the batteries last for six hours, but the clever part is that they come with their own recharging station that doubles as a case.


The headphones come with larger black silicone tips and smaller white tips. It was found that, the black tips were the best accommodate and the hooks help to keep the buds in place without falling out, after you have given the buds a small twist towards the front.

Syllable recommends the D900 for use in the gym and says they are sweat proof. The pairing process is as easy as any Bluetooth headphones, even though it is confusing as each earbud shows up individually in the list of pairable devices. You must pair only one, then pair the earphones to each other.

It is very easy for the buds to be misaligned so you need to check that the faint red charging light is on for both buds once the lid’s on. A single press of either button pauses and plays music, while a double press redials the last number you called. If you get a call while listening to music, you can answer it with a single press, or reject with two presses.

Build quality is average, sound quality is a notch below that. As long as you can get a good fit and therefore good seal with one of the ear tips you will get great bass. Overwhelming bass in some cases. There was no problem to be found with echoing, so the noise cancellation appeared to be doing a decent job.
