Jaybird X4 wireless headphones
but not truly wireless) headphones
it not been for the several bugs or weak battery
pair of earphones offers an entirely flat-sounding experience
poor battery life and lots of bugs
are surprisingly uncomfortable over long periods of time
the proprietary charging dongle is restrictive
The battery life might also be too short for a whole shift
the fit is probably not comfortable enough for a full day of work
No cherry-picked units sent by brands
have any auto turn-off setting
There is no auto-off function on the headphones
only have one set of ears
There is also no proper sound stage
It struggles to isolate your voice from background noises
They are not made for swimming
Ultra-Tail runner Bosio has terrible taste in EQ
sound juvenile or bloated
not the best for hearing the nuances in your favorite tracks
comfy long-term for some ear shapes
device-wide lag in the Bluetooth connection
feature a sweat and waterproof design
none of the tips work in their ears
they have trouble getting the earphones to connect to their device
wireless connection often doesn t want to work or experiences dropouts
earphones put out a premium sound
the price and the fact that they use a special charging cable
it s not IPX rated and can get damaged by water
the buds only support SBC and AAC Bluetooth codecs
poor build quality
the over-the-ear fit is not optimal
Geolocation doesn t show where they are right now
the built-in mic works a little too well
X4s are not the cheapest pair of sports headphones on the market
reliable audio quality
earphones are not programmed with automatic shut off during periods of inactivity
these headphones are a bit on the more substantial bass range of sounds
the wireless capacity sometimes has issues when in crowded areas
Some delays is expected given the current climate
the battery monitoring is not accurate and the battery life itself
these earbuds are not comfortable to wear for extended periods of time
noise of it bumping up against skin
melodic traffic jam-starts to sound a little muddy
waterproofing is the designers had to remove the charging port
Bassy
powerful and a bit muddled Honesty
Bluetooth earphone market was pretty barren
The Bluetooth market is crowded to the brim with competition
but it doesnt charge and impossible to turn them on ever again
heavy-handed use of bass seems to swallow up a lot of the detail
AAC won t cut as much out of the file
undercut by the harsh fit and seal of these headphones
