Philips Fidelio S1 and S2 are affordable in-ear headphones
Philips has released the first two pairs of earphones in its Fidelio range: the S1 (£80) and S2 (£130).
The Fidelio S1 headphones have an aluminium enclosure and a single-layer diaphragm, while the S2s are fitted with a lightweight copper alloy housing and a multi-layer diaphragm designed to damp resonance at high frequencies.
Both models feature 13.5mm neodymium drivers and sport a semi-open back design.
The S1 and S2 both have in-line microphones and single-button remotes for use with smartphones and tablets.
Accessories include various eartips – four sets for the S1 and seven for the S2 – a hard-shell carrying case and a tangle-free cable.
