Syllable D900S Wireless Headphones Review

D900S Headhones with ear inserts

The Syllable D900S earphones are a great idea but I struggled with the fit

I’m a big fan of cord-cutting so the Syllable D900S wireless headphones seemed right up my street. Who wouldn’t want to eliminate wires from their audio listening experience?

With all this innovation, I was excited to get my hands on a pair of Bluetooth wire-free headphones from Syllable and find out whether the hype can live up to real life.

My overall experience with the D900S wasn’t great and doesn’t reflect the majority of the positive reviews on Amazon. I really wanted to like these headphones but, for me, they are massively lacking in the comfort and connectivity.

It’s not all bad though, the packaging and charging container that the D900S come with is fantastic and the sound reproduction isn’t too bad either… but… a big ‘BUT’ here… the actual earphone plastic looks and feels cheap (for £60) and they just won’t stay in my ears.

Design & Comfort

It’s going to be a rather short section when it comes to the design & comfort of the Syllable D900S wireless headphones. I’m not a fan of the shiny black plastic as it easily picks up grease marks and looks, in my opinion, a bit cheap for a £60+ pair of headphones. In fairness, the white model does look a little more premium from the pictures I’ve seen.

It’s the little niggles that make these earbuds feel cheap like the uneven LED light distribution and slight rough edges where the two sides of the plastic mould meet.

The design & ergonomic flaw that left me feeling really disappointed was the soft ear inserts. They’re way too flimsy and oddly shaped. Whichever way I try to insert them into my ears they always end up coming loose or falling out. I’ve tried both of the sizes provided with no luck. The ear arch support just doesn’t have enough tension to hold them in your ear.

Conventional soft in-ear earphone moulds have been around for a while now so I’m not sure why Syllable has tried to re-invent the wheel here. It clearly hasn’t worked and leaves the headphones, for me, pretty unusable.


Sound Quality

To test the sounds quality I had to hold the earphones in to create an air seal before I could reproduce any kind of pleasing sound. In fairness, if you have the right ear match for the S900S, then you’ll find they have okay sound quality but not fantastic.

Connectivity & Hands-free

Connecting the headphones to your phone is simple and easy through your phones Bluetooth settings. The second earphone connects to the main earphone automatically producing true stereo sound.

Final thoughts on the D900s headphones

On paper the D900S headphones from syllable seem to offer a great solution to cable cutters everywhere. If you can manage to lodge them in your ears they produce a decent range of bass, mids & highs but, for me, that’s a big if.

Do I recommend the D900s? Unfortunately not, the headphones aren’t ergonomic enough to allow a comfortable fit and kept coming loose or falling out.

Want them anyway?
