Toto jsou moje oblíbená konzumní sluchátka pro internetové telefonování v práci i pro děcka ve škole. 24.2.2021 jsem koupil už asi čtvrtý nebo pátý kus - a ouha: zatímco předchozí kusy byly bezchybné, tenhle pátý budí rozpaky: měl mušle zapojené navzájem v protifázi (to jsem si opravil, prohodil jsem polaritu pravého měniče) a co je horší, mikrofon dost hnusně brumí. Snad o 20 dB víc než u předchozích kusů - kdyžtak mám vzorek nahraný (srovnání starého a nového kusu). Porovnáním starého a nového kusu sluchátek jsem dospěl k závěru, že za to může přímo použitá mikrofonní vložka. U problematického kusu reaguje intenzita brumu na přiblížení ruky k mikrofonní vložce = chytá elektrostatickou složku rušivého pole 50 Hz (v záznamu je nejsilnější třetí harmonická = 150 Hz). Pinoutem to není, při opačné polaritě mikrofon nefunguje. A kabelem to taky není, protože ani nový ani starý kabel nemá pro mikrofon koaxiální vedení. Mikrofonní vložka má uzemněný kalíšek = OK.

Impedance
This indicates how demanding the headphones are on the power source. Headphones with a lower impedance (e.g. 32 Ω) are ideal for mobiles and laptops. Higher impedance (e.g. 80 Ω and above) is more suitable for Hi-Fi players and amplifiers.
Frequency Response
Indicates the sounds the headphones can reproduce. The standard range is 20Hz–20kHz, which corresponds to what the human ear can hear. Lower Hz = deeper bass, higher kHz = more detailed treble.Specifications
