Wireless earbuds have a lot of potential. This looks like a starting point, but I wish things would move faster. ANC is the obvious next feature to add, but there are features that could be implemented at a mediocre cost and massive benefit.
EQs that could flatten the magnitude response. Allpass filters (or FIR if delay is acceptable) could minimize group delay. Microphones could be used to adaptively update the filter values.
These techniques have been used in telecommunications for decades, but audio has been “good enough” for longer, so these features have remained barred behind absurd costs and the implementations have decayed into trash. I see wireless earbuds as a platform that could lead to proper audiophile quality for all. The parts are cheap and the engineering is easy. The only showstopper is not having a market...
This is one of those areas where it's hard for me to understand why we'd change.These devices make so many tradeoffs for mild improvement in utility.
I know I'm not the target audience, but I don't get how someone would pay so much for these audio products and not pay close enough attention to audio quality/fidelity to notice the downsides. To me, they seem like a stylish, stereo Jabra.
The target demo for expensive earbuds are either people with too much money, or people who are financially irresponsible. The battery will last two years before planned obsolescence kicks in.
Guess what, consumers are willing to pay for convenience. I don't think that's a very foreign concept. Anyway the audio quality of wireless earbuds have been good enough for the average consumer already. Not everyone is an audiophile who listens to FLACs, you know
I got a free set of Nokia buds and while the sound quality was adequate the battery life was terrible. I might use them again in summer as they are cooler than over ear phones but was definitely underwhelmed. I haven't tried them running as I always leave my phone behind.
we've changed since companies kinda forced us to. it started with Apple creating a problem (removing the headphone jack) and then solving it for us with a solution that conveniently making them more money. other solution were far less preferable by most people like having dongles that have their own downsides. most people adapted to buy the given solution and just turned their face to the other way when facing the clear disadvantages. other companies just followed suit seeing the economical benefits of creating those "solutions" .
I can't use these true wireless earbuds, I'm the only person I know who can notice, but the sound between the two channels isn't always synchronised and it is really offputting.
I highly recommend you try our any of the Apple Airpods. The H1 Chip inside them takes care of synchronization. Most, if not all, True Wireless Earbuds have a relay system, the device (like your smartphone) transmits audio to one earbud, which then relays the signal to the other.
In Apple's Airpods, both the earpieces receive the signal directly from the device.
Apple has a patent of how to sync the audio between two buds that are no physically connected. First gen of Android chips had to get around the patent and they weren't good. The second gen that came out near the end of 2019 supposedly are as good as Apple's as far as syncing.
