TINHIFI T4

First of all I want to address something up front. My Tin T4 came in a white box, not a black box. Everything else was identical except for the cable. It's not the same cable that's pictured or that you've seen in reviews. In my opinion, it's an even better cable. It's a 4-core or 6-core braided cable with a 90-degree 3.5mm plug, but it feels very nice and is very flexible. The terminal is not as beefy as it is on the pictured cable, but this is a small gripe because this cable is seriously very, very nice. Additionally I found the mmcx connectors on this cable to be buttery-smooth and had no difficulty getting them connected properly. Sound quality is superb. Beyond superb. These IEMs have the widest soundstage I have ever heard on am IEM and they really let everything breathe and sound fantastic, particularly on very fast or very complex tracks. The detail is amazing, especially at this price point. These produce some serious details. Additionally, instrument separation is extremely impressive for a sub-100 dollar IEM. I mean really, there's nothing these little IEMs can't handle. Let's talk about the low-end for a little bit. You read a lot of reviews stating that these don't have enough low-end for a basshead, and that may be true. But for the average listener I would say this low-end is more than enough to be satisfying. Kick drums are percussive just as they should be. There's decent rumble when it's called for -- but it's all so incredibly well-controlled and detailed that it works perfectly. Very, very tight bass with fast attack and excellent decay. There is no bleeding whatsoever into the mids. Mids are slightly forward without being biting. They sound nicely detailed. Vocals sound lively and superb, a lot of weight to vocals here. The treble is bright and crystal clear, and very airy. These are definitely a bright-neutral IEM and the detail and clarity they reproduce -- especially for under 100 dollars -- is simply stunning. There is no harshness at any frequency and no sibilance to speak of, it's a perfect balance of detail and clarity without anything grating happening. Regardless of what I've listened to, I've experienced no fatigue whatsoever and honestly, the day I got these I wore then for 12 straight hours. No exaggeration. The comfort is stellar, as you might have guessed by my wearing them for 12 hours at a time. I do it often. I am always listening to music. And everything -- absolutely everything -- sounds good on these. Maybe some electronic stuff won't have the bass you're looking for, but that's only a maybe, because again I feel that for the average person, these have plenty of (well-controlled, detailed) bass, even with electronic music. These are an absolute steal at 99.00 dollars. Buy them.

This is the second set of the TIN HiFi T4 Inner Ear Monitors that I have owned. Both sets have had issues with the right channel playing weak / low volume sound, when compared to the left channel. I am disappointed and frustrated. Out $200 + because this company refuses to warranty, refuses to help with the issue. I like the sound and I like the comfort and feel in the ear. I am extremely disappointed in the quality of less than 1 year worth of use, these are essentially useless to me, as the right channel just does not function properly. I have tried with different audio sources, different cables, etc. and there is clearly an issue with this model and the right channel. Customer service cannot help. I am extremely disappointed and will likely never purchase another Linsoul product.

I use these earbuds on my desktop computer for both music and voice. The quality is quite good, with an appropriate balance of bass and treble. The connecting thin cable is sometimes inconvenient, but this product is more convenient than having to charge battery-operated earbuds (which eventually fail to charge).

Why did you pick this product vs others?: These are very good. I’ve had mine for two years. Use them every weekend. Only reason I’m giving 4 stars instead of 5 is because of what every one else is saying. The cable is crap. Uncomfortable and falls out of ears. So I got a replacement cable. For 17 dollars. And it is now my favorite IEM. I also have a high end mackie. But I prefer these.

UPDATE: As of today (2/27/20) a full refund has been processed. So while this still hasn't been a great experience and the product was defective, I'll bump the rating up a star for that. So I purchased this item on December 11, 2019. It showed up in early January, due to having to be shipped internationally. It seemed to be very good quality, and I was pretty happy with it... for about 20 minutes. Sound quality was good, definitely a step up from what I currently have, but the sound started cutting out on one side. Looking around now I see a lot of people complaining about problems with the cable connection, so this isn't an uncommon issue. But I couldn't manage to fix the problem, so I looked for warranty options. I spoke to Linsoul about it and we discussed a return, as in order to claim warranty I'd have to send it back to China anyways. On January 9th, they sent a $20 refund (to cover return shipping). I sent the package off a few days later, I believe on the 12th? (shipping was about $23) And have not heard a single thing since. No confirmation, no full refund, nothing. I know it's international shipping, but it's been definitely over a month at this point, and I don't know if there's any chance of getting back what I paid for a faulty item. Will definitely update this review if things go through, but right now it's not looking great. Would not recommend risking your money on this purchase. TL;DR: Sound was good, but the cable is bad and seems to be faulty for a lot of people. Warranty and returns both require international shipping, and it doesn't look like I'll be getting a refund for the purchase. So all-in-all, I'm out $100. Lesson learned.

I'm not sure why Crin et al, are so so about these headphones; they rock!. Seriously, their bass is extremely tight, exhibiting no bloat, and communicative; they have excellent detail and what I would consider a perfect balance of mids and highs (neither fatiguing, boring or shouty). They don't come between you and the music; these are the first IEMs I've heard, which I could listen to, as easily as my favourite over-ear headphones.

One earpiece on my last pair fell apart after a few years of very heavy use. I tried to glue it together but clumsily ripped the wires out in the process. Within 15 minutes I ordered another pair. I couldn't live without them. They sound that good. They compare very well to full size high quality headphones I have. One minor complaint is the plastic cover near the ear that forces you to wrap them around your ears. They stay seated in my ears way better without them and are far more comfortable. An easy bit of surgery with great benefits. Order them. You'll probably love them.

Thought the sound was good at first. But there seemed to be a noticeable improvement in sound quality after about 30 hrs or so of listening and once I had the right sized tip fitted. Sound is amazing now considering the price.

Son de muy buena calidad , los recomiendo mucho y más si te dedicas a la producción musical 🙂
