I want to ask for your experience, how are your smartphones dealing with Bluetooth latency?

While any decent dedicated video app have possibility to adjust time delay to negate latency of BT connection, we are so far getting kind of random results when it comes to other apps such as Youtube or games.

Follow Apple/Sony's way of making both right & left earbuds connect to the device independently and you'll eliminate the latency issue :p

All of my BT5.0 TWE's (list in signature) have been fine with most apps - YouTube, Netflix, videos through Chrome. With some delay is nearly 0 seconds, with a few It's been as high as 0.1-0.15 seconds. I think only one (BT20 was above 0.2 seconds)

Bluetooth itself has latency around 150-200 ms, so there should always be some latency.

Oh definitely, I meant audible not measurable lol

0.2 is still hearable, at least when you know what to listen for. Especially when you get to games.

My question was more regarding apps, if you know some other apps that are automatically detecting connected BT headphones and setting audio/video delay due to them.

All my apps have imperceptible latency with my S10 phone and Bluetooth earbuds, except for web based videos through Opera mobile. I guess this is due to the apps sending the delay offset, while Opera browser isn't aware it's playing a video and thus does not set a delay. For this, the shortest delay I have encountered is with the Sony wf-1000mx3, there is a very tiny delay but not annoying like other buds.

PSA: for those with access to amazon.de , the much talked Mpow T5 now come with a 10€ off voucher. Great. Like 10 days after I shelled out the full 60€. Well, still happy with them.

Just got my Earfun Free Oluv edition - first impressions is that the sound relatively neutral with a slight warmth, with a tiny bit of sparkle in the treble and some mid-bass emphasis. Bass is a bit rumbly but not muddy like some of the reviews of the standard edition. A bit deeper sounding than the Astrotec S60, but not as much detail retrieval. Much louder with more stable connection off my phone, but I have noticed a certain rumbling stutter artifact that happens occasionally.

Off my BT 5.0 laptop with SBC, it sounds similar but a tad bit more muddy with the midbass sounding more bloated, and the treble with a more metallic shimmer. Piano sounds become more confusing in piano-hiphop/chillhop/lo-fi tracks. Even so, it is still a respectable sound I would not be dissatisfied with.

EDIT: It also has a bit of pressure with the seal for me. I can hear the sound fade a bit when I'm eating or something and when I take out the bud on my right ear, the flange flips back.

'Would not be dissatisfied with'. What does that mean? :)

Like L.A. Beast finally trying out the re-release of Crystal Pepsi :p It's a good implementation of SBC, and if I didn't know how it sounded with AAC I would think it's fine. It's not as distorted as Astrotec S60.

Wireless charging compatibility of Earfun Free:
ADATA CW0100 (10W) - Works fine, although this is not desirable due to the wireless charger using microUSB. Odd since overall I've had some compatibility issues with it depending on the power brick and cable I use.
Samsung Wireless Charging Stand (2019) - Does not work at all. I know this is a vertical stand, but I also I tried tilting it and repositioning the case.
MYCELL wireless charging power bank - Doesn't work. This was the only charger I have that works with Astrotec S60 (albeit generating a lot of heat).

Good news: Earfun Free also supports Type C to Type C PD charging, so it's not merely a USB 2.0 IC with a Type C connector (the typical cost-cutting measure used by some of the Chi-Fi TWS). I personally don't use PD charging often, but it's nice to see this as a true Type C device.

No one uses TWS in mono mode, especially nothing over $20.

I'm sure that people on this forum (and similar forums) would be happy to weigh in on decisions like this.

And we very much appreciate you providing information on here! This communication goes a long way in purchasing IEM's of a specific brand.
I've actually been keeping my eye out for a pair of TWS that could be used in mono. Specificly, a pair where either could be the master or slave bud. This is because i'm totally blind and need
to be able to hear an employee if they come over to ask me a question...or if my boss walks over to talk.
Even if the Sennheiser MTW didn't have charging issues, the battery life is subpar compared to nearly every cheaper product on the market, and you can get a better-sounding true wireless model for less than half the price of the MTW.
i just posted the other day about how my MTWs weren't quite 10 times the SQ of the anbes 359 despite being 10 times the cost. But i wanna hear that TWS pair or multiple if mor than 1 that sound better than the MTW. Which model are you refering to?

I often use just one of my Earin M2 when listening to audio books as they can be used in mono and either bud can be master or slave and either left or right
