I tend to tangle and snag cables when putting bikes closely together.
Also my helmet doesn't fit properly on the stem. It's always colliding with cables. Small nuisance when parking my bike somewhere. Pretty annoying in rare cases where I don't want to ride with a helmet.
@Willeke ah it's like "pro: supple tyre, con: supple tyre". I think there's a good reason I usually don't read bike reviews. I don't know any other product where press fails so badly.
Gimmicks that look good on social media often sell... in this case, particularly if the target audience knows nothing about "real" bicycles and how good they can be
modern wireless earbuds are incredibly good... even though "real" headphones technically have better audio quality, the closeness/directness plus noise-cancelling really give a certain immersion. squeezing a battery, antenna, RF modem, signal processor (DSP), several sensors and microphones into such a tiny space is impressive
Only point is there's no black magic in audio. Pretty good isn't all that expensive or innovative if you don't try to bend physics: low frequency need large size and fine temporal resolution needs wide bandwidth.
