There are a number of us that wandered into this thread during the pandemic and haven't been able to leave. Welcome to this world of wonder! I'm drinking a cup of coffee and still can't believe the value you can get for a number of buds that are cheaper than this coffee. At this very moment, I'm listening to the Tmusic buds I picked up for just under $10. After compensation, these sound so incredibly headphone-like it's just mind-blowing. My last iem purchase was the LZ A7 (awesome iems) and this earbud has better staging than the A7.
TMusic 32ohm Bery?
I tried many good drivers with simple PU diaphragm (low and high impedance) but also drivers with different coating.
If these layers are done the right way and if the driver is given more attention when tuning, the performance of these drivers is really impressive and this is most noticeable with drivers with a higher impedance. All DIYers already knows that.
Some sellers on Ali which sale DIY parts, from time to time they assemble a few models, such as the TMusic Bery for example, and sell it at a very reasonable price.
This provides an opportunity for all those who do not want to assemble their model, try the "exotic taste" of different types of drivers.
Let me show you a case where the difference between an assembled model vs. separate parts is not so negligible.
Me and
@FranQL discussed this yesterday. This
DIY model for example use 400ohm graphene driver (one of the best top3 DIY driver) and beautiful shell.
The price is around $60 which is the price range of several excellent branded models. This driver can reach a bit higher price range for sure.
Now let's take a look at how much each part costs separately if, say, we want to assemble the same model ourselves.
Note: Shell has your own matching housing for mmcx, so we need cable without connectors. Also, we have 3 color versions and 2 different size (for 14.8 and 15.4mm drivers)
We need 3 pats:
Driver (~$20) +
Shell (~$15) +
Cable (~$5) = $40. So we have $20 price difference for the assembly service.
What I noticed, when it comes to drivers with lower impedance, the price of the service is lower, the higher the impedance the price of the service is higher which makes no sense because the job is the same
What should be noted is that there is no QC here.
In general these drivers are not to be underestimated at all, and can be quite surprising with their sound, as @Sam_L noted
This is also one of the great advantages of earbuds because you will rarely see a case where one of the DIY sellers puts together some DIY IEM
