Fantastic sound and build quality.

Definitely not overhyped. Battery life is insanely long. Sound quality is up there. This could be my only DAC and I would be okay with it. Build is sturdy and is aesthetically pleasing.

For the cons. App needs some work. Starting from a first song of an album via bluetooth, it fades in 1 second. That means then first song of an album or playlist will sound cutoff at the beginning. Button command take getting used to. For example, lowering the volume, you will need a song tp be playing. The 0.3 second gap needed per volume adjustment doesn't feel responsive.

Despite the cons, this device quickly rose the ranks in my audio collection. You've got fast charging time on top of the long battery life. Microphone with noise cancelling. And it sounds like a more musical onix alpha xl1.

Rien à critiquer... que du bonheur
J'ai acheté le BTE-9 suite aux conseils de Andy de audiovault et quelle agréable surprise, il connaît... et il à lexpérience.
Le BTE-9 correspond à 100% à mes besoins à tous les niveaux
La tenue de la batterie
Le bluetooth me permet de me balader dans toute la maison
La qualité du son... super
Comme me l'avais dit Andy, la synergie avec mes IEM Kefine quatio est magnifique..
J'ai un ampli ifi Black label avec un casque audeze Closed Back
Et mon ensemble BTE-9 ET KEFINE QUATIO me donne beaucoup plus d'immersion et de plaisirs musicales
Ce petit dongle est magique je recommande à 200%

Smaller in size than expected. But quite powerful. Surprised that it even drives Hifiman Ananda through 3.5mm. Any plugs are easy. Bluetooth sound is good, but through cable it's somehow quieter. Gain doesn't change the volume much. I would like more buttons and a clip at the back. Overall, a decent device.

A sensational device that should receive more attention. Excellent cost-benefit ratio. And it doesn't owe anything to some well-known, popular, and highly hyped brands. I recommend it to everyone who knows the brand.
