for the ultimate no compromises compact gaming PC look no further than the

obsidian series 250d from Corsair click now to learn more welcome to my second

3
00:00:17,400 --> 00:00:24,519
premium imem video the edotic er4 PT

4
00:00:21,439 --> 00:00:26,880
contrasts sharply with the i8s that I

5
00:00:24,519 --> 00:00:31,519
looked at last time where the i8s are targeted at consumers with their basey

6
00:00:29,400 --> 00:00:36,879
sound signature great comfort and stylish look the er4s are targeted at

7
00:00:34,800 --> 00:00:41,239
professionals with emphasis on high accuracy sound and exceptional noise

8
00:00:38,960 --> 00:00:44,879
isolation that's not to say however that general consumers can't enjoy an

9
00:00:43,280 --> 00:00:48,680
accurate in your monitor as much as a professional for many purists out there

10
00:00:47,160 --> 00:00:52,120
hearing the music the way the artist intended for it to be heard is more

11
00:00:50,800 --> 00:00:57,160
important than pumping up bass or playing around with EQ dials to make it

12
00:00:54,520 --> 00:01:02,719
sound better so with that in mind here we go inside the plastic hard box that

13
00:01:00,760 --> 00:01:06,320
has everything inside of it we find an accessory package that really looks more

14
00:01:04,400 --> 00:01:10,840
like equipment you'd find in an audiologist office than something you'd

15
00:01:08,439 --> 00:01:15,119
expect to find in a consumer product box uh everything appears to be designed

16
00:01:12,680 --> 00:01:19,720
with practicality in mind but you do get a lot of stuff with the er4 pts

17
00:01:17,200 --> 00:01:24,920
including a shirt clip an airline adapter an 8 in to4 in adapter two sets

18
00:01:22,880 --> 00:01:29,920
of large and one set of small three flange ear tips two sets of glider ear

19
00:01:27,360 --> 00:01:35,159
tips two sets of medium foam ear tips tips a filter removal tool and four

20
00:01:32,720 --> 00:01:40,880
filters to help smooth frequency response and prevent wax buildup an er4

21
00:01:37,680 --> 00:01:43,360
PT to er4s adapter cable that improves

22
00:01:40,880 --> 00:01:48,000
sound accuracy but also increases impedance so it might not be optimal to

23
00:01:45,159 --> 00:01:55,040
use with your phone or other MP3 player a user's manual a warning and finally oh

24
00:01:52,479 --> 00:01:58,719
yeah a carrying case and finally the earphones themselves there is one more

25
00:01:57,320 --> 00:02:04,439
thing and it's actually a little bit unique this is a signed Channel matching

26
00:02:01,960 --> 00:02:08,080
compliance graph showing that one of adom modic technicians personally

27
00:02:06,079 --> 00:02:12,879
checked to ensure that both of the balanced armature acq drivers behaved

28
00:02:10,720 --> 00:02:17,800
the same way than signed off on it before packaging your product and

29
00:02:14,599 --> 00:02:20,160
shipping it to you a very nice touch now

30
00:02:17,800 --> 00:02:23,879
it's time to focus on the earphones themselves they look like a piece of

31
00:02:21,959 --> 00:02:29,080
equipment and feel like a piece of equipment the rnl indicators are simply

32
00:02:27,239 --> 00:02:32,599
a red dot for the one that goes in your right ear which is is fine if you're in

33
00:02:30,879 --> 00:02:38,360
a recording studio but a pain in the butt if you're on a dimly lit bus each

34
00:02:35,120 --> 00:02:41,560
earphone has a unique uh thin Twisted

35
00:02:38,360 --> 00:02:43,959
wire lead that goes back to a bulky

36
00:02:41,560 --> 00:02:48,159
heavy join and then a much thicker heavier 4ot wire well the overall length

37
00:02:46,400 --> 00:02:53,360
is 4 feet but the the gauge of the wire is much thicker here um it's unfortunate

38
00:02:50,599 --> 00:02:58,040
that it's so long and heavy because particularly with the three flange tips

39
00:02:55,840 --> 00:03:02,440
which sounded best for me the weight pulled on my ears in a way that was

40
00:02:59,840 --> 00:03:07,840
pretty uncomfortable the included clip is an inelegant solution at best and

41
00:03:05,200 --> 00:03:11,959
instead I opted to wear them upside down and run the wires over my ear like this

42
00:03:10,280 --> 00:03:15,519
they aren't designed to be worn that way but it worked reasonably well and saved

43
00:03:13,680 --> 00:03:18,959
me at least once from having the flanges uncomfortably jerked from my ears

44
00:03:17,640 --> 00:03:24,720
although there was a time when it didn't save me and that was when I decided to wear it that way comfort-wise I'm not

45
00:03:22,640 --> 00:03:29,400
going to beat around the bush these are the most uncomfortable earphones I've

46
00:03:27,280 --> 00:03:32,959
ever used your mileage may vary of course

47
00:03:30,280 --> 00:03:38,080
but when the user's manual simply says moistening eases insertion for the

48
00:03:35,560 --> 00:03:42,519
flanges that's a pretty strong indicator that edotic is aware of the situation

49
00:03:40,760 --> 00:03:47,680
Lube up because you ain't going to like it much otherwise uh the foam ear tips

50
00:03:45,080 --> 00:03:50,879
don't hurt but like all foamier tips they wear out relatively quickly so

51
00:03:49,480 --> 00:03:55,959
that's not really an option for me I don't want to be ordering new ones all the time and the gliders weren't an

52
00:03:54,159 --> 00:04:00,480
option for me either because they don't seal as well so their noise isolation

53
00:03:58,200 --> 00:04:06,640
isn't as good as the others and the base response is not as strong as the

54
00:04:03,040 --> 00:04:07,920
others okay so thanks Linus they feel

55
00:04:06,640 --> 00:04:11,760
like a tool rather than a toy and they're uncomfortable so why do they

56
00:04:10,000 --> 00:04:16,759
have the right to exist do they have any redeeming qualities the answer is yes

57
00:04:15,280 --> 00:04:21,880
let's start with their passive noise isolation I don't have the equipment to

58
00:04:18,959 --> 00:04:26,720
validate their 35 to 42 dbel claim so all I can do is describe the experience

59
00:04:24,280 --> 00:04:31,919
for you once you get them inserted they're so deep that even yawning

60
00:04:29,320 --> 00:04:36,680
doesn't affect the sound the feeling of your surroundings shifts it's like

61
00:04:34,600 --> 00:04:41,080
walking from a crowded Ski Lodge out into an empty Forest after a fresh

62
00:04:38,720 --> 00:04:45,199
snowfall the entire world just has a muffled and subdued feel to it and the

63
00:04:43,160 --> 00:04:48,759
only thing left is the sound of your own thoughts except instead of it being your

64
00:04:47,199 --> 00:04:52,560
own thoughts that you hear it's your music without needing to turn up the

65
00:04:50,759 --> 00:04:57,759
volume to compensate for environmental noise everything sounds as crystal clear

66
00:04:55,440 --> 00:05:01,520
as if the sounds were being beamed by Magic into your head every instrument is

67
00:05:00,039 --> 00:05:06,160
easily discernible from the others to agree that I've never experienced before

68
00:05:03,919 --> 00:05:10,800
the difference in Clarity is noticeable when I compare the er4 pts to the entire

69
00:05:08,960 --> 00:05:16,000
rest of my stable of headphones which includes several other products in this

70
00:05:12,800 --> 00:05:17,720
price range and more interestingly the

71
00:05:16,000 --> 00:05:21,800
difference is noticeable with sources that ranged from listening to music on

72
00:05:19,440 --> 00:05:27,960
YouTube all the way to uncompressed files of songs that I know very very

73
00:05:24,240 --> 00:05:30,800
well there are some caveats though with

74
00:05:27,960 --> 00:05:35,720
accurate sound comes to some people boring sound there is no emphasis on

75
00:05:33,680 --> 00:05:40,319
bass to speak of and emotic has optimized for isolation rather than

76
00:05:38,440 --> 00:05:45,080
sound stage one of the things that stood out to me about the ie80s was how

77
00:05:42,600 --> 00:05:50,400
relatively open they sounded for an IM whoops there goes my phone the er4s

78
00:05:48,199 --> 00:05:55,120
take me right back to that traditional between your ears sound that is

79
00:05:52,639 --> 00:06:00,080
characteristic of IEM something else I noticed was that switching between the

80
00:05:57,240 --> 00:06:07,160
i8s and the er4s felt like Chang in the lights in a room from from a warm glow

81
00:06:03,160 --> 00:06:09,039
to a a Cool Glow either is fine once I'm

82
00:06:07,160 --> 00:06:12,800
used to it and after 15 minutes I'm completely adjusted but side by-side

83
00:06:11,199 --> 00:06:16,039
listening tests were actually a little bit unpleasant because the sound

84
00:06:14,479 --> 00:06:22,319
signatures of these two products contrast so starkly going from I80 to

85
00:06:19,639 --> 00:06:27,319
er4 makes the er4 sound Bland and uninteresting while going from the er4

86
00:06:24,599 --> 00:06:32,240
to the i8s make them sound basey and muddled by comparison

87
00:06:30,000 --> 00:06:36,759
so what's the takeaway from all of this bottom line they're just not comfortable

88
00:06:35,039 --> 00:06:41,840
enough for me to use them as my daily drivers during the day the heavy cable

89
00:06:39,120 --> 00:06:45,720
was a bigger inconvenience for me than I actually expected and when they snag on

90
00:06:44,039 --> 00:06:49,840
something accidentally they're very painful even with them wrapped around my

91
00:06:47,199 --> 00:06:54,280
ears and at night uh not being able to tell left from right without turning on

92
00:06:52,400 --> 00:06:58,800
a flashlight is a pain and then the fact that I normally sleep in my IM IMS which

93
00:06:56,599 --> 00:07:04,440
is not happening with these is a showstopper as well but they weren't

94
00:07:01,960 --> 00:07:08,400
designed to be daily drivers for general consumers just look at the website I

95
00:07:06,479 --> 00:07:12,840
mean it's functional sure you can get replacement parts order custom ear molds

96
00:07:10,639 --> 00:07:16,879
for 100 bucks which is actually really cool custom ear molds will fit you

97
00:07:14,400 --> 00:07:20,599
perfectly so Comfort problem goes away and you can learn about the product but

98
00:07:18,560 --> 00:07:24,720
it looks like a hearing aid store or something they're catering to a

99
00:07:22,080 --> 00:07:30,560
different crowd and comfort it aside for me they sound amazing I could listen to

100
00:07:27,759 --> 00:07:35,160
them with zero fatigue for hours and I have so if the objective is not to be

101
00:07:33,199 --> 00:07:39,199
fashionable but rather to get precise sound delivered to your eardrums with as

102
00:07:37,280 --> 00:07:43,879
little outside interference as possible then the er4s get a big thumbs up from
