Wireless earbuds for daily listening

The SOURCEPRO i07 are true wireless earbuds with Bluetooth 5.1 connectivity and a charging case. They deliver stereo sound with dynamic drivers and support AAC audio decoding. Touch controls handle playback and calls. The IPX7 rating protects against sweat and rain during workouts.

Bluetooth 5.1 range and codec limits

Bluetooth 5.1 provides a stable link within typical indoor distances. The earbuds only support the AAC codec, so high-resolution aptX or LDAC streams will fall back to AAC. Latency is low but not eliminated, so competitive gaming may still notice a slight delay. The case charges in 1.7 hours via USB-C.

Check your device and fit before ordering

Verify your phone, tablet or laptop supports Bluetooth 5.1 and AAC for best quality. The in-ear design requires a secure seal; if the supplied tips do not fit, isolation and bass will suffer. Buyers who need on-ear comfort or multi-point pairing should consider other form factors.

Questions about this item

Which version gives me 27 hours of total listening time?

The i07 earbuds with the 400mAh charging case deliver 27 hours combined playtime; the buds alone run over 9 hours per charge.

What does the 20kHz treble figure mean when I am actually listening?

It marks the upper frequency limit the drivers can reproduce, so high notes such as cymbals or vocals stay clear without rolling off early.

How does Bluetooth 5.1 affect connection stability and latency?

The 5.1 chipset provides faster pairing, a more stable signal and low latency, reducing drop-outs during calls or video playback.
