Merely days before the upcoming launch of the 10 flagship, HTC continues to tease fans with the specs and features of the flagship lineup. The tech manufacturer now hints that the HTC 10 will have "the best BoomSound yet."

According to a teaser video that HTC posted, one of the main features of the upcoming HTC 10 is its audio. Building from its previous "we're obsessed" theme, the new teaser expands from focusing on the design of the HTC 10 to the flagship being able to deliver "the highest-quality sound possible." In addition, the company promises that the flagship's audio will not be just the regular surround and mixer-based one, but a "flawless, high fidelity on your phone."

Since HTC has already posted the teaser, it may already an indirect confirmation that the new flagship has been overhauled and definitely improved on. Because of this, fans will be looking forward to the HTC 10's launch on April 12.

In connection to the launch, speculations suggest that HTC will be adding another surprise for fans. Reportedly, aside from the HTC 10 being a flagship lineup with at least two versions, HTC will be simultaneously launching a new addition to the mid-range Desire lineup.

According to Phone Arena, the new addition will be a modest version of the HTC 10 and will have the mid-range Snapdragon 652 processor under the hood. However, since the new lineup is a flagship, this version will be regarded as a Desire iteration. Codenamed A56, the new addition will reportedly come out in single-SIM and dual-SIM versions.

This will be in addition to another HTC flagship iteration, the HTC 10 Mini. However, the Mini version is still in the works, and rumors place its release date to be sometime toward the end of the year, possibly by September.
