works for what i need it for

d0ug - 9 months ago

Yes, I'd recommend this product.

i was skeptical about buying this because of the previous reviews. i took a chance and bought it anyway for my note 10+. I haven't used it a lot but it does work properly unlike the previous reviews stated not sure whats different. Only thing i found is i use a fast charger and when plugged into this, it charges at normal instead of a fast charge.

Not compatible with Apple earbuds due to mic

3.5mm headphone jack only works for 3 band headphones jack Audio only (ground,left,right) Apple iPhone earbuds have 3.5mm jack with 4 bands (ground,left,right,mic) will not work with this.

Excellent sound, huge problem with design

YoussefEB - 1 month ago

The sound is excellent, but the design is SUPER flawed. The cable is very stiff, which would be ok for other applications, but it's inevitably gonna be bent for an audio cable, which it cannot withstand on the long term. The cable regularly breaks down. Aside from that, the design is generally just super unergonomic, with the stiff cable it protrudes a further 5-10cm from the phone, making the whole unwieldy, and the hard edges of the adapter part get stock while taking it in/out of the pocket -- and this should be an audio cable !!

It works, but I can't talk using it.

Zoe Money - 1 month ago

It works like it's suppressed to just fine. My biggest issue is I have to put my phone on speaker to talk to anyone in the car. Why did I have to constantly use speakerphone instead of leaving the device plugged in? I'm still looking for a great decide that does all 3.

Works but seriously limits volume

Mikejaja - 9 months ago

Compared to my last similar adapter, this one seriously limits audio output. Even at full volume on my phone and stereo, noise level was still underwhelming. Will be returning this soon.

Audio OR charge

Joshua Kraemer - 1 month ago

The unit that I have refuses to both charge and play audio on my Oneplus 6T phone. Connecting a charging plug causes the adapter to no longer work for sound, and it will continue to not work unless I restart my phone. Waste of forty dollars.

Hi Joshua, The Belkin RockStar F7U080 has not been tested to be compatible with your mentioned device. As a workaround, try using the Belkin RockStar adapter with another compatible device and see if it charges and plays audio at the same time. If the issue persists, shoot us an email, with your contact details and the link to this review at, so that our Product Experts can assist you. Regards, Kyla Belkin Support
