I'm here to ask suggestions on which wireless earbud to pick.
I previously owned Jaybird X3s, but I sold them because I wasn't satisfied about the microphone quality. It was almost impossible to have a conversation on the phone.
My budget is under 100€ and I was looking at these models:
Beyerdynamic Biron BT
Optoma NuForce Be 6i
Optoma NuForce Be Sport 4
Sennheiser CX 6.00 BT
Sennheiser CX Sport
I've already checked their specifications and it seems to be like the Sennheiser CX Sport is the best one, due to a wider frequency range and and high impedance. Unfortunately their too expensive for my budget.
Of the group, the "second best one" should be the Optoma NuForce Be Sport 4 (32 Ohms, 10 hours of battery life, quick charge, range 20-20 kHz and IPX5 certified).
I also read online that the Beyerdynamic are very good (despite lower impedance) thanks to a wider frequency range, but they're not IPX5 certified, have a lower battery life and don't have the cable clip (which is important to me).
What should I pick?
I'm a little bit confused. What is better: high impedance or wider frequency range?
My previous JayBird X3s had 20-20 kHz frequency range, 16 ohms and a 6 mm dynamic driver unit.
