00:00:00.080 --> 00:00:07.520
you know what really burns my popcorn bluetooth i mean sure it's convenient

00:00:05.839 --> 00:00:13.440
and those little wireless speakers are super handy but i've got a lot of

00:00:09.599 --> 00:00:15.440
problems with bluetooth and now

00:00:13.440 --> 00:00:20.640
you're gonna hear about them first off guess which frequency band bluetooth

00:00:17.440 --> 00:00:23.119
uses surely it couldn't be 2.4 gigahertz

00:00:20.640 --> 00:00:27.519
right you know the same one that every wi-fi router blasts out a signal on

00:00:25.519 --> 00:00:31.920
making the band more clogged than a toilet at chipotle oh wait yeah that's

00:00:29.920 --> 00:00:36.399
exactly what frequency it uses so from the get-go your little bluetooth devices

00:00:34.160 --> 00:00:40.719
are already competing with tons of other wireless traffic which can reduce your

00:00:38.160 --> 00:00:46.399
effective range but hey i'm just getting started why exactly is bluetooth so

00:00:44.079 --> 00:00:50.320
range limited in the first place look i know that whenever you're using

00:00:48.640 --> 00:00:55.039
something wireless there's a trade-off between range and battery life since

00:00:52.800 --> 00:01:00.399
blasting a signal farther away sucks down more power but what good is long

00:00:58.239 --> 00:01:04.320
battery life if i'm constantly having to worry if i'm too far away from my

00:01:01.840 --> 00:01:09.200
bluetooth speaker i mean sure sometimes it's not a big deal but i

00:01:07.200 --> 00:01:13.200
don't want the signal to be so anemic that it just drops out if i take my

00:01:11.119 --> 00:01:17.439
phone into the other room because a few sheets of drywall are in the way come on

00:01:16.159 --> 00:01:21.280
oh and while we're talking about drop-offs let's move on to another

00:01:19.200 --> 00:01:25.360
common source of frustration pairing issues you'd think they could have made

00:01:22.799 --> 00:01:29.200
this simple like wi-fi your gadget sees another gadget like your phone and your

00:01:27.360 --> 00:01:35.040
router do and they just they just connect they just do it but no

00:01:32.400 --> 00:01:39.360
instead you have to take the extra step of putting your devices in discovery

00:01:37.439 --> 00:01:42.560
mode before they can see each other turns out that unlike wi-fi where you

00:01:41.119 --> 00:01:46.479
can usually just see a network automatically you can't do this with

00:01:44.560 --> 00:01:50.399
bluetooth unless you have some optional additional technology strapped on like a

00:01:48.399 --> 00:01:54.479
pair of nfc transmitters and once you deal with that you get another headache

00:01:52.560 --> 00:01:59.280
because the powers that be created bluetooth profiles one for streaming

00:01:57.360 --> 00:02:03.439
music one for phone calls one for connecting your computer mouse and so on

00:02:02.000 --> 00:02:06.479
and while i get the reason they did this was to save battery life here's the

00:02:05.439 --> 00:02:12.800
problem none of these things have been tested to play nicely with each other which is why

00:02:10.640 --> 00:02:16.560
sometimes your car's infotainment system will work better with your phone than it

00:02:14.959 --> 00:02:20.879
does with your friends and to make matters worse newer devices use what's

00:02:18.879 --> 00:02:25.280
called smart bluetooth where they don't even have to support every feature in a

00:02:22.640 --> 00:02:28.560
certain profile while this is again supposed to extend battery life by

00:02:27.040 --> 00:02:32.640
allowing a gadget to turn off features it's not using it makes it even more

00:02:30.640 --> 00:02:36.560
likely that a pairing problem will arise because of all these random profile

00:02:34.400 --> 00:02:39.840
combos you also have the fact that some bluetooth devices are supposed to be

00:02:38.160 --> 00:02:44.640
able to connect to multiple other gadgets at once but are so low power

00:02:42.640 --> 00:02:49.360
that their little embedded processors can't handle the extra traffic resulting

00:02:47.040 --> 00:02:53.920
in even more dropouts but now i'd like to talk about an issue

00:02:51.680 --> 00:02:57.760
that absolutely drives me nuts when i'm trying to watch video

00:02:55.519 --> 00:03:01.360
latency whenever i'm watching a great episode of tech wiki with bluetooth

00:02:59.599 --> 00:03:06.000
speakers or headphones it's like watching a badly dubbed kung fu movie

00:03:03.519 --> 00:03:10.720
because the audio track is so out of sync and the basic reason this happens

00:03:08.400 --> 00:03:15.760
is because bluetooth has relatively low data rates yet again to preserve battery

00:03:13.440 --> 00:03:19.040
life and hopefully improve range meaning the audio data takes a little longer to

00:03:17.760 --> 00:03:24.800
reach your wireless speakers or headphones than it would with a wired solution your devices also have to do

00:03:22.720 --> 00:03:28.560
extra processing which is often inefficient because many operating

00:03:26.879 --> 00:03:33.040
systems Android haven't been well optimized for

00:03:31.440 --> 00:03:38.239
quickly dealing with bluetooth audio i mean imagine that a wireless device

00:03:35.920 --> 00:03:42.879
hasn't been optimized for a wireless audio standard are you kidding me and

00:03:40.560 --> 00:03:48.400
yet they took away our headphone jacks who's in charge here and yes i know

00:03:45.440 --> 00:03:52.640
there are codecs like optics adaptive that are supposed to cut down on latency

00:03:50.400 --> 00:03:56.640
but it's often still noticeable due to core issues with the bluetooth spec

00:03:54.640 --> 00:04:01.200
whatever operating system your device is using and the inherent limitations of

00:03:58.799 --> 00:04:05.599
wireless audio if the powers that be haven't optimized audio by now it

00:04:03.599 --> 00:04:10.720
probably isn't surprising that bluetooth is also notorious for not being the most

00:04:08.000 --> 00:04:14.239
secure wireless protocol either as the myriad ways it has been implemented has

00:04:12.720 --> 00:04:18.239
made it tough for the industry to come together and figure out how to lock it

00:04:16.079 --> 00:04:21.680
down not to mention it's had tons of vulnerabilities surfaced since it was

00:04:20.000 --> 00:04:27.360
first released so is there any way to make your bluetooth

00:04:23.840 --> 00:04:29.120
experience a little better well

00:04:27.360 --> 00:04:33.040
the best things you can do are to keep all of your bluetooth devices up to date

00:04:31.280 --> 00:04:37.840
and disable any features you won't be using in your device settings doing both

00:04:34.720 --> 00:04:39.520
of these things can cut down potentially

00:04:37.840 --> 00:04:43.520
on frustrating pairing problems otherwise

00:04:41.199 --> 00:04:47.280
maybe just use wired devices unless you really need bluetooth i mean having your

00:04:45.680 --> 00:04:52.960
headphones connected to your phone with a wire and a dongle is that it's not

00:04:49.440 --> 00:04:55.199
that big of a deal guys come on

00:04:52.960 --> 00:04:58.880
get over yourself speaking of things that could be a big deal are you

00:04:57.120 --> 00:05:02.240
concerned about a data breach causing your credit card info to fall into the

00:05:00.479 --> 00:05:07.440
wrong hands then check out today's sponsor privacy.com techwiki for a free

00:05:05.759 --> 00:05:11.120
easy to use service that hides your credit card number you see it works by

00:05:09.280 --> 00:05:14.800
creating a virtual card number that's locked to whichever merchant you're

00:05:12.560 --> 00:05:18.960
shopping at so even if the merchant gets hacked the bad guys won't be able to

00:05:16.479 --> 00:05:22.240
just use your card anywhere they please and if they try you'll get a push

00:05:20.639 --> 00:05:25.919
notification so that you're always in the loop and can cancel the card

00:05:23.759 --> 00:05:29.039
immediately cards are super easy to set up you just need to create an account

00:05:27.440 --> 00:05:33.919
link your virtual cards to your checking account or debit card add a limit and

00:05:31.840 --> 00:05:36.720
