Frequently asked questions about this product
How many hours of listening do the StreetMusic Coral offer?
4 h per charge in the earbuds, plus 16 h in the case, for 20 h in total. The earbuds charge fully in 1 h and the case in 1 h 30 min over USB-C. Four hours in a row is half a day: get into the habit of putting them back in their case.
How long is the supplied charging cable?
30 cm, USB Type-C. It is a spare cable, designed to fit in a pouch rather than to connect the case to a wall socket behind a piece of furniture. Any other USB-C cable will do the job if needed.
What are these earbuds made of?
100% recycled plastic, GRS-certified — the Global Recycled Standard, which verifies the traceability of the material — and the cardboard packaging is FSC-certified. Two audited labels, rather than a mere green claim printed on the box.
Can they be connected to a computer or a TV?
Yes: they are stated to be compatible with Macs, Windows PCs, smartphones, tablets and TVs as long as the device has Bluetooth. The stated range reaches 20 m over Bluetooth 5.4, with the AAC and SBC codecs.
How good are the 13 mm drivers?
13 mm is a generous diameter for an earbud of this size: a larger diaphragm moves more air, hence the deep bass that is advertised. Expect 16 ohms of impedance with a response of 20 Hz to 20 kHz.
Do calls come through in both ears?
Yes: the built-in microphone provides stereo calls through both earbuds, more comfortable than a mono headset as soon as a conversation goes on. Playback control, volume and Google Assistant or Siri are also operated from the earbuds.
Do these earbuds have active noise cancellation?
No. No electronics cancel out the outside noise: what you hear from the street depends solely on how the earbud sits. For extended use on public transport, a model with active noise cancellation remains more comfortable.
Is the set bulky to carry around?
31 g for a 50 × 45 × 25 mm case: it slips into a jacket pocket or the front pocket of a bag without you feeling it. The stated latency also stays below 200 ms, which is fine for watching a video.
Are these Energy Sistem earbuds new and under warranty?
Yes, new and genuine, with the invoice serving as the warranty document for 1 year. The reference for this Coral colour is 8432426459223, which is also the EAN code: it is what identifies the product for any warranty claim.
