On the Samsung Galaxy Tab S9+, it works perfectly.. while other cheaper ones I tried did nothing.. So for me, it's worth it... and it has very good sound..

I got it for the Doogee Smini and it works to listen to music, e.g., from YouTube, but you can't hear or be heard on a phone call. Also, the phone has an FM radio app, which also does not recognize it as an 'antenna'.

Update 2024-12-06: For the Doogee Smini, I eventually got the product "Edifier GM180 Plus In Ear Gaming Headset with USB-C connection" from Skroutz, which is fully compatible for music and phone calls. It also couldn't activate the FM radio.

Very good sound quality on Samsung S10 and Note 20 mobile phones. It is recognized immediately without any adjustments. Very good construction and durability. Highly recommend.

5 out of 5 for their price. They are compatible with all the phones I have tried (s24 ultra, redmi note 11, mi max, realmi 55c, oneplus nord, etc). Unknown what chip it incorporates, but it has strong and clear output. It appears durable and of good quality.

Very good product, it connects and recognizes all my devices and the sound quality remains good. The cable is protected inside a special braid and does not easily break.
