64 Audio U8 & U10 IEMs

Sep 1, 2016

I'm swaying on U2 and U4-SE. Judging from RM44 comment on the U2, they may just be the viable option for me, but Chris's comment on the U4-SE sounds extremely intriguing and it's a damn shame nobody really has ever reviewed them. Though it is said that the bass is toned down and the mids and highs are more elevated in the U4-SE tuning, they are still based off the bass-heavy U4, so possibly the B1 module would be the best pairing for these pair....? Don't quote me on this. This is just all speculation.

Sep 1, 2016

DicloneusI can understand the issue with choosing between U2 and u4se. But keep in mind u4se will not be available again. The way I look at it, for $200 more you get a lot more than U2, uniquely tuned with Audiophile signature in mind. I've ordered a u4se with B1. More fun for me and my wallet is crying

RM44You brought up a good point there. I read somewhere that the new apex lineup doesn't necessarily differ in the driver tuning, and the only difference is the modules. I don't know how valid this information is since I haven't tried any of 64 audio products before, but that being said, if that rumour is true, I'm leaning more towards the U4-SE now.
How's the sound signature of the BA drivers from your perspective? Is the bass a rounded and smoother "punchy" kind of air movement, or more of a sharper "strike"? I can probably then get a rough estimate of the sound signature if I can get an idea of how 64 audio's drivers sound like. I personally own TF10 pro (my golly the new TriFi was astonishingly great btw), so if it is at all possible, if you can feed us with a little wee bit more info on the drivers relative to the TF10, that would be highly appreciated.
Kudos to you for helping the drop community out with all the info!

DicloneusYou're welcome. I've been in the same boat a few months back trying to know the various models in 64audio lineup and this unique ADEL technology. So I'm sharing whatever info I've gathered and my experience with their products.
Even the APEX technology would be similar and this older U series would support both ADEL and APEX.
Bass to me is rounded and smoother "punchy". It is not sharp. I've a dynamic driver (DD) IEM and a Dynamic driver/BA hybrid IEM and to my ears, the bass isn't much different from a pure dynamic driver or hybrid iems. The 64audio iems that have 4 drivers for low end has sufficient rumble in the sub-bass region, good texture and good quality and not just quantity. Also it doesn't overpower the mids. The tuning is done very well. Kudos to 64audio.
The quality of the product and a very pleasant/supportive customer service is also a plus. Very professional, knowledgeable and very prompt.
The highs and lows could extend a bit more on the U12. That's more of a recommendation for future improvement and not a negative. U12 with S1 sounds congested and sometimes veiled. In some songs it might be more aggressive too. But with MAM, B1 etc, it is incredible.
Right now 64audio has the equivalent of S1 module in APEX. Waiting to see the other modules showing up in the coming months. Especially the equivalent of MAM. MAM can be tuned to replicate the other modules (more or less) and the real plus is the ability to tune each ear differently to get the similar sound. Each of our ears are different and MAMs help a lot.
Even with MAMs the sound doesn't leak out. So no need to worry about disturbing others.

RM44Impressive work on your research. I guess 64audio made the U4-SE to better suit the Asian communities judging from brighter-sounding songs being favoured more compared to the bass-oriented North Americans. It's quite interesting that the bass is more of a smoother quality resembling a sound signature produced from dynamic drivers. I guess ADEL is at work here. I remember reading a review about how the ADEL series is reminiscent of over-ear open-back headphones simulating wider soundstage. I guess the modules allow room for music to "breathe" if you will.
A person like you, who has done extensive research equipped with a well-round understanding of 64audio products, and decided to go with the U4-SE with B1 module, this gives me a good boost of confidence level in clicking that Join Drop button now with the same item selected.
Thanks a lot for the descriptive info RM44!

DicloneusAll the best @Dicloneus with your U4-SE. You got it right with ADEL being similar to open back over ear headphones. It really removes the pressure and allows the ear canal to "breathe". Plus no more ringing of ears after using ADEL. My aging ears definitely thank me.
Also note that I've the S1 module and MAM to use with U4-SE as needed. But I feel that B1 should be a good pair up with U4-SE. Eagerly waiting for it to be shipped out. Adding modules over time isn't a problem, if needed.

RM44Now I worried that these won't be good for airplanes.

RM44From what I've seen so far, the port holes are different between ADEL and APEX, so they can't be used between different tech.

travelinjackThey aren't as good as a completely sealed IEM. That being said, a fully closed manual module does work pretty well, as there is no attenuation.

travelinjack @travelinjack: I don't think you should be. ADEL is quite a unique technology 64 audio has adopted in their products in that it does not act as an ambient port to let users be aware of their surroundings and their immediate environment often seen in high-end IEMs. Since the ADEL port is plugged with the module of your choice, there will be no leak in sound to the outer environment, nor does it let ambient noise in to the shell itself. You can see ambient ports in conventional CIEMs as an intake of ambient noise, whereas the ADEL ports act as vents to neutralize pneumatic pressure, thus relieving damaging effects to your eardrums.

verlorenIn fact, it does read here: https://www.64audio.com/product/apex-m20-modules that they are backwards compatible with all previously sold A & U Series earphones.

Sep 2, 2016

travelinjackThe effect of hearing the sound is similar to a open back headphones without the drawbacks of the open back headphone. The music being played doesn't leak out and won't disturb others even in MAMs in fully open mode. The isolation (what ambient noise is let in) varies among different modules. S1 has the max isolation and MAM fully closed mimics that to a great extent. The other modules B1, G1 have lesser isolation than S1 (DB levels listed on the description page of this drop)

RM44Thanks. Sticking with the U10 with S1 then.

Should I exchange the PC38X for better headphones?

I bought the PC38X headphones FOR GAMING and they are great, but I have NO use for a Microphone since I don't do competitive gaming and I was wondering if there were better headphone options at a similar price without a headphone, where (presumably) more of the cost was put into making it sound better. I also find that my PC38X don't get quite as loud as I would like and I was wondering if a cheap amp like the iFi Go link would draw a little more volume out of my phones. https://www.amazon.com/dp/B0BN6MM822?psc=1&ref=ppx_yo2ov_dt_b_product_details I went with the PC38X since it was considered the best bang for buck headphones. I care most about using spatial apps like DOlby Atmos and DTS Headphone:X. Suggestions are welcome.

Looking for a gaming/content audio setup

Hello! I'm looking for recommendations on audio setups. I'd be planning on using it mostly for gaming. Preferably I'd like a pair of large closed back headphones since I have a big head and jaw. I'd also like to hear myself through my mic with mic monitoring. As far as budget goes, I don't really have one. But under 600$ would be nice. I can go higher if needed. The audio setup would be connected to a high performance PC. Thank you in advance for any recommendations!

$10 Drop Coupon Email not sent?

Trying to buy some gear off Drop for the first time. I was told I would receive an email with a welcome to drop $10 off promo. I never received that email. Drop was able to send me emails for my login token and email for Password update. But for some reason the $10 off coupon was never sent to me.

Hello, I just joined, primarily for the audiophile products. Looking at purchasing the NHT C3 speakers for our new living room. Space is about 15 feet wide by 33 long and they will fire long ways. Space is just for general listening, music room with all equipment is downstairs, so hoping they will fill it with sound nicely. Cheers.
