About this deal
The feedforward mic and feedback mic collects the internal and external ambient noise to generate a reverse sound wave to reduce the noise. So the Edifier 330NB only offers a max of 5 hours does question why you would purchase these when other alternatives provide a stronger battery life. Moving to the mids they are also nice and rich and they aid the vocals and instruments to be clear without being overwhelmed by the bass. The TWS330NB controls by touching the middle part of the stems, which can be hard to locate blindly.
It’s also something to consider if you listen for long periods like when you go on a bike ride who wants a battery to die mid-ride. What you will notice is that you don’t have controls for skipping back a track or any volume commands.I was using them quite happily, but last night i left the Earbuds box (which holds the buds) on charge and forgot to disconnect it when i went to sleep. When you finally get the buds out of that charging case and listen to your favourite music or podcasts you will notice the battery life provides 5 hours without ANC and when you switch on ANC this drops slightly to 4 hours off a single charge according to Edifier. Lower mid-tones, which normally provide music with warmth and flow, are barely boosted, resulting in this TWS sounding clear rather than warm. In this review, we have been testing the TWS 330NB which is the latest in the Edifier lineup we have been sent.
I found the fit actually also helped prevent them from falling out of your ears when walking to work or even when I used them for a Spin class recently.
In articulated, easy-going songs like Angels from The XX, the sub-bass isn't afraid to show a stab you can feel, but those instances are rare.
Watching videos is flawless on the TWS330 NB, with spot-on synchronization between audio and video on both Android and iPhone.The 330NB also comes with Ambient mode which is designed to let in more of the outside noise in and the performance of the feature is not great unfortunately when you switch between ANC and ambient mode it’s hard to tell the difference. They come in an adorable matching case and you’ll get about 20 hours of playtime with a full charge.
