Gonna make you watch the whole thing this time. There is a lot to digest, so take small bites if you have to.
I hope the next review is a little less convoluted.
Be careful, be safe, be nice. Love y'all and nothin' but peace to you!

I am amazed that something like this was not noticed by the engineers listening to the first set before they made 20,000 units. Mr. Diamond ears. #1💕

[@BassDad8]

@@cheryljones3596 I swear sometimes I feel like the finished product isn’t actually listened to, just graphed. I mean if I look at the graph and I know what drivers I’ve used and everything checks out… but in practice or IRL as they say, something could be amiss…

[@innovance3788]

Nooooo! That's kinda heartbreaking, I've been enamoured with them ever since i saw they graphed similarly to the delci, but with what looked like a less fatiguing treble. But after recently having an unvented iem cause my ear to pop and losing sound in the midrange of my left ear for 3 weeks, it became clear that poorly vented iems are not worth it nor worth the risk!! So thank you for being frank about it as these were very much on my wanted list. I think pressure build up is something that bothers some people and has risks for some people too, so it's definitely something to let people know might be a potential issue or that they should watch out for. And it's not like you gave it a bad review, you gave it a glowing review, it's just there was also a physical compatibility issue that presented an unignorable problem, resulting in what is a reasonable conclusion...

[@BadBunnyBad-y9h]

Your reviews are so accurately perfect. Thank you.

[@_-Z-]

That really sucks about the pressure issues. They sound like a really great set, otherwise. You don't ever apologize for being honest about your experience, though. Some people might take it as you crapping on their favorite new set but everyone is different and I think all feedback is important (good and bad) in aiding to a final purchase decision. Thank you for another great review! 👍

[@j.w.s.743]

I haven’t experienced pressure build up before personally but I completely understand. No one is going to wear a set of iems that are painful. I still will try to get them in the future based off of your description of the sound of them. Hopefully I won’t have my first experience with pressure build up.😮 Great honest review as usual!

[@FabioMiyake]

Next time try foam tips, they really help to relieve the pressure build. Love your reviews, thx for your hard work.

[@apollomoonlandings]

Reddit member sforzabull is a really cool dude who has a nice sense of humor. I have nicknamed him the King of Cables (as if he is the king of a country) since he always manages to find fantastic looking cables which he aesthetically pairs with IEMs in his huge IEM collection. He doesn't simply pair in terms of aesthetics. Instead, he also pairs in terms audio quality and cable quality. It is delightful to hear that he loaned these IEMs to you for your review. So to sforzabull and his wife, I want to say that you both totally rock. 4:41 My guess is that Myer-Audio also is the OEM for the Juzear 61T, especially since the 61T cables are the same, and since the shells look like shells which Myer-Audio would design and label. 16:31 Is the 61T technically a non-vented IEM? The 61T appears to have vents which are smaller yet similar to the vents on the DaVinci which are also located in a similar position below the 0.78mm connector jacks on the shells. You mentioned that you also tried Tangzu Tang Sancai Balanced eartips which have textured umbrellas which are designed to relieve pressure with non-vented IEMs. The Sancai eartips work well for me with non-vented IEMs. So wow! I am surprised that these eartips did not work for you with the 61T. Another wow factor, which I have experienced, is that even very slight yet unnoticed internal ear pressure can affect the overall perception for how well any IEM sounds. This might explain why some reviews for the 61T seem to be noticeably divergent in terms of soundstage and imaging since even slight yet unnoticed inner ear pressure can noticeably affect not just the overall sound signature, but also other things such as the perception of resolution and imaging. Anyway and for what it is worth, I really enjoyed watching and listening to your review. I also really like the fact that you simply "call it as you hear it" in your reviews.

[@BassDad8]

@@apollomoonlandings There does seem to be a vent, or an attempt at a vent exactly where you noticed it. I’m just not sure it makes it through to the acoustic cavity. And interestingly, I could “adjust” the amount of pressure with a particular ear tip once inserted, but I kept having to adjust it every time I moved my head, or my jaw, and it just got tiresome. I keep thinking about what I would do if I actually owned them. I’m thinking I would keep trying up until the return window was about to close. For sonic performance at that level and for that price, I definitely would still be working on it if they were mine…

[@BassDad8]

@@apollomoonlandings oh and that Xinhs cable he (the King) included did something… I dare not say what… but I noticed (ssshhh).

[@apollomoonlandings]

@@BassDad8 Thank you for your reply. One thing which I noticed about the vent position on the DaVinci (and apparently the same as on the 61T), is that this results in poorer outside noise isolation, and in particular for noises behind me such as my apartment air conditioner. Do you experience the same? Anyway, tour observations are enough to tell me that the 61T apparently is not a truly vented IEM. This is good to know. Perhaps the 61T does slowly vent over time, yet this is not good enough even if true. I suspect that this IEM would be pretty horrible to use while walking or jogging. Perhaps you could do some quick tests to confirm?

[@BassDad8]

@@apollomoonlandings I had issues just puttering around my desk with a balanced extension cable attached. Every time I thought I had them set just right, I’d move and lose the “good” seal that it took my 15 minutes to get. So no, I’m not recommending for walking or jogging. However, if someone does not have the venting issues I did, and has a set if ear tips that will provide a good and stable seal, they might be fine with the 61t on the go. I have my doubts though…

[@jamesberryman9893]

Oh man, I have had this set on my wishlist for about a month, and now I'm glad I didn't pull the trigger. I appreciate your honesty and saving me 200.00. They are still a beautiful set, but that pressure, though...

[@BassDad8]

@@jamesberryman9893 I am in the same boat. I’m still considering buying them for myself…. If I had only found a viable solution…

[@alvarg]

one solution for the pressure if you have some cheapy tips that seal well is to use a pin and poke a small hole in the side of the inner tube. it can help excess pressure without ruining the sound.

[@Jan_de_Mor]

great and honest review!!!! 🙌would appreciatte a detailed comparison between those probably related iems, the butterflies, the CKVLX and the Sliivos...

[@jb678901]

Thanks for the excellent review, as usual. I wonder if there was a quality defect within these particular IEM's, whereby glue inside the shell has obstructed the vent. However, if the issue is consistent for both Left and Right IEM's, it lends me to think it is a design flaw...or a manufacturing defect. In any event, I will keep my powder dry vis a vis the 61T. PS: One should not have to valsalva half way through each sound track!

[@k.w5804]

Aligns with my impressions from 2 days of use. The first iem that I've ever had problem with ear pressure, and that discomfort doesn't go away after I take them off, it stay for good hours. It isn't as bad as it was to you. On this set, great seal = awesome bass and immersion, but you notice the pressure build up in 30-60 mins. Or trade isolation for pressure relief. I used Baroque, but bass sounds a little bit muddier, and the stage sounds unrealistically wider. It's definitely worth the price for the sound, cable, and build, but only for certain people.

[@someoneusa]

Damn you're on a hell of a roll. Keep up the honesty and real person approach, looks like it's appreciated by the growth on your channel. 1000 here we go!!! Fudu needs to be exceptional if I'm going to keep it and you know how I feel about Delci. I don't want to spend a penny more if a set isn't adding anything to my collection. I'm already thinking what cheaper set can I mod to sound like 61t,lol. Stage is one of those things that is hard to mod. And it sure is pretty! How does it compare to og Adonis? You got me very interested in that set. It's gorgeous and has a very unique tuning. Edit - Fudu just got here! Holy hell that was fast...

[@JAG3RmanJENSON]

I will say this set has given me the hardest time with tips and I’m constantly swapping tips every time I use them. But they sound amazing when you can get them set up right.

[@BassDad8]

[@vaynesh2827]

Great review, and really the first one I saw that brings up the venting issue. Thank you for your honesty. I've got this set because it graphs with a slightly reduced upper mids which is my preference. Once I've put them on I've immediately noticed the venting issue, oddly I haven't seen this mentioned anywhere else. Tankfully I don't feel any pressure, instead the sound is bass anemic when I insert them, but this goes away in about 5-10 mins, so there must be some kind of pressure venting in place. I wonder if the venting holes are so small that they can get clogged up by dust (they certainly look pretty small and have that rubber inster in them). It's still not perfect though, I definitely feel my ears getting tired a lot faster listening to these than my other IEMs. But the sound is just so good, the bass has a really nice impact but doesn't take over the sound signature, while the vocals still shine for me, without being shouty.

[@BassDad8]

@@vaynesh2827 for all of the reasons you mentioned, I am still considering it a contender for my iem of the year. I’m considering buying a set to see if it has the same issue. Maybe I just have a low tolerance for it. But when I was able to keep them in for more than a few minutes, I loved what I heard. Thank you for your feedback! ☮️

I have a set of these on the way. The pressure issue is concerning. If it becomes an issue for me, I'll just have to mod the set by drilling a microscopic hole/port. I had issues with pressure in the past with the Fatfreq IEMs and any set that is all Balanced Armatures (Studio 4). The pressure build-up causes that crazy nausea, and I wouldn't wish it on my worst enemy

You had me going for awhile, I thought you were going to crap all over them lol. I can’t wait for mine, they are here any day now. Try divinus velvet wide bore or tangzu tang sencai tips. Foam as last resort. Edit maybe not tang sencai lol, divinus wide don’t take bass away though. Foams probably mud it up? You could cut the foams short so there is no foam to absorb the treble. Also you can size down your tips to elevate pressure, or pull up on your ears.

[@BassDad8]

@@Hijynx87 all good advice and if I owned them, I’d still be working on a solution. I’m just tired after 2 days of “almost”. They’re just so good. But they’re headed home tomorrow.

[@Hijynx87]

I bet that’s why practipile didn’t find the set technical, pressure issues. He gave them a 1.5/3 for technicality. Needless to say he didn’t like them. Timmy was somewhat the same, but he likes more pinna and treble (probably a low volume listener as well). He said the detail was about the same as the aria 2 though. I’ll find out for myself though probably tomorrow hopefully. I’ll have to compare it to my favorites like hype 4, doscinco, fh9, performer 8, quintet, Falcon ultra, origin etc.

[@BassDad8]

@@Hijynx87 it is SO far above the Aria 2 in technical performance. That’s just silly. Sorry Timmy. And a 1.5/3 is also a joke. I wonder if the pressure was the issue for both of them. I’m pretty sensitive to that so I knew as soon as I put them in I was in for a battle.

[@larrydunn4626]

is it possible your set had a defect... a blocked vent? How is it even possible for a vented IEM build up pressure, unless the vent is blocked? Can you ask your friend to take a small sewing needle, push it through the vent (carefully) and see if the vent is actually open on the inside of the faceplate?

Personally, the budget silver bullet, in my humble opinion, remains the ARTTI T10. I've coupled mine to the KZ AZ20 BT5.3 earhook (or the cheaper AZ09 Pro / CCA BTX that lacks AptX HD and Snapdragon Sound Tech but still offers BT5.2, AptX/SBC/AAC). The T10 is easy to drive, very comfortable, and competes with the higher end planars (imho). On AliEx sale, it's hovering below $50. The AZ20 is below $65...and AZ09 Pro/ BTX is below $30....when on AliEx sale. PS: Easy to mod these earhooks to standard B-Pin from factory C-pin/QDC.

On a seperate note, don't quote me, BUT, pretty sure Myer has said they are Juzear OEM or use same OEM, something of that nature. What does the pressure feel like? Is that driver flex?

Pretty sure that's normal and the brain saying, can you please gimme some quiet time?! I don't do quiet and earphones unless I'm sleeping.

[@BassDad8]

No. The pressure I am experiencing is just like putting in a pair of earplugs. The non-permeable kind, not the foams. It is an airtight feel that got more uncomfortable as I listened. Those drivers are moving air and there seemed to be nowhere for that air to go. I am not claustrophobic, but they sure made me feel like I could be...
