How sound quality is impertinent in selection of a smartphone
Loudspeaker – Let’s start with the loudspeaker. It’s a pretty simply test, we max out the volume of the speaker to get an idea of how easy the phone is to hear while playing back movies and music, etc. This is particularly useful to know if you want to hear a hands-free call in a noisy environment or want to watch a movie while your family chatter away in the living room.
Speakers and the quality of audio coming out of it can be an important parameter for those who rely on heavy video streaming or video conferences. If you like entertainment-on-the-go, buy a handset that has front-facing speakers. This gives clear sound even while holding the smartphone in landscape mode.
If you don’t indulge in video streaming or video conferencing much, then a regular handset with bottom-firing speakers should be just fine. Those with speakers placed at the back are also fine.
Headset – On to the internal DAC and amp, which is the component connected up to your 3.5 mm headphone jack or USB Type-C side-pin ports if your phone doesn’t have a 3.5 mm jack. Again the quality of headset is important in this case.
Bluetooth codec support
Finally, with wireless speakers becoming increasingly popular and cableless headphones closing in on the quality of wired models, support for matching Bluetooth codecs is increasingly important. Furthermore, those passionate about music quality might want to take advantage of higher resolution Bluetooth codecs like Qualcomm’s aptX HD and Sony’s LDAC.
