I'm no expert, but for a TOTL IEM that is say > $1500 USD, in the big scheme of things, how much can u save using a Bellsing driver instead of a Knowles driver?
a lot, if a pair of bellsing drivers is 5$ in bulk and the same knowles is 15$ and you sell thousands of those flagship earphones the savings are huge
we don't know exactingly what kind of drivers they are using, there is very cheap bellsing drivers, also very expensive knowles, i saw bellsing drivers for 5$ a pair, at bulk the price will be lower than that, Knowles have drivers for 60$ a pair, we are talking big savings here

I've been saying that Bellsing drivers are in some cases even better than Knowles ones. Everytime I said it people would dismiss it faster than it took them to read it.
The only issue and reason why Bellsing has a bad name is because they are mostly misused without much thought in cheap IEMs. And because they are cheapper - that must mean that they suck, cuz that has always been the case in audio community...

The copying part I didn't know about - I legit though that Bellsing was manufacturing BAs for Knowles because that made a lot of sense. At least now we know and finally have a reason not to use Bellsings due to ethical reasons.

bellsing drivers are not bad at all, if tuned right they can be good, for example the woofers on CCA C16 are great, very clean fast bass, also i have one earphone with 6 knowles and 4 bellsing per side, the bellsing drivers are for the treble, not at all bad treble, they use knowles dampers in the tube and the treble is smooth

You guys have any preferences for Chi-Fi Bluetooth receivers that are clip type (with a 3.5mm jack) rather than the ones that attach directly to the IEMs?

Has anyone ever tried one of these? I'm leaning towards the Fiio, but if one of the cheap ones does the job I'm not opposed to saving 20€ and buying a backup pair of C10s instead :wink:

If you want a simple bluetooth adapter and your phone support Aptx, go for the Ugreen Bluetooth 5.0 Aptx adapter. Cheaper than Fiio. But if you want Bluetooth adapter with DAC/Amp, https://www.head-fi.org/threads/the...n-es100-btr3-w5-up2-and-tempotec-blue.906655/

Cool, I'd seen the ugreen adapter as well - I can get that from Amazon locally for about 20€, so 3€ more than waiting a week or two for shipping from China. I'll read a few reviews and then maybe give that one a try - looks good so far.

I don't think I need an amp - so far all the Chi-Fi IEMs have been super easy to drive with my OP3T and my old Sony MW600 (which is the BT adapter I've been using so far - but the clip broke off and the call audio quality is very bad compared to more modern bluetooth systems).

I often fight with so many tips on certain earphones
Until recently, I had never bothered with premium tips and didn't have a clue of their benefits. Then I purchased a few Spinfit, Spiral Dots, and Ostry...and, thereafter, owing to circumstances, was solicited by Spinfit and Azla to review their stuff. Received a selection from Spinfit this week.

When rolling all these little rascals with different iems, there is a lot to be learnt. They work wonders in some cases and do nothing in others. These brands are no real competitors imo as they all do different things. I'll analyse each brand and their usability and, as a grand finale, they will all be thrown into a cage to fight it out between them. Expect a gory and entertaining massacre.

One first result: they don't come cheap.

I have a few of the Xiaomi Bluetooth receivers, and I really like them. Good sound, good build quality (including aluminum clip), no dropouts, and they’re a small as a AAA battery!

BL-03 impressions right out of the box: energetic and bassy, with very inoffensive tonality. Stock tips are kind of hilariously bad and I settled on Final Audio large tips (I usually use medium tips on other IEMs). Not kings of detail or isolation, but I am enjoying them quite a bit.

Deep. Very deep. Just run an frequency response vid on youtube and the bass was there from 20hz. It isn't quite as pronounced as on the Semkarch but that isn't an entirely bad thing.

Note that these are just some ramblings from my first couple hours of listening with my FiiO A3 and some flac albums, pre burn-in as well.
Bass extends about as deep as the MH755 with enough juice (!), very full-bodied and kind of creeps into the lower mids on some tracks. But in others, like "Hide" by Juice Wrld, the bass is in its own little realm and doesn't take away focus from the rest of the spectrum.

Oh my, you're right. I'm sure that YouTube does weird compression with audio but at least on this video I can hear bass frequencies right away from 20-21 Hz. :dizzy_face: MH755 bass becomes noticable, for comparison on the same setup, at around 28 Hz for me.

To aid in getting go fit on short stem iems like the blons, insert the stem of a smaller tip inside the stem of a larger tip, which allows it to stay up higher on the stem improving fit. Also trim off stems to fit as sleeves at the 2 pin cable/iem junction to stabilize connection.
Boy do these puppies sound great
