1. Is there a microphone you know that would suit me these requirements?
2. The Olympus ME-52W is the best I have found, it has high sensitivity, noise reduction and it has direct 3.5mm connector so I can replace its cable with a shielded one very easily. But the question here is: can i use this microphone with my setup, since it is ment to be used with the voice recorder? Seems that it needs phantom power to work? How do I know if i can supply this? UPDATE: Seems that without phantom power this microphone is useless. Thus, i need an option that doesn't require phantom power.
3. How do i protect the microphone from collecting 50Hz noise from the surroundings with its cable? Should i use a shielded cable? Most mics come with their own unshielded cable, and replacing should not be an option for me..
4. Do XLR cables help with this? Can i use a 3.5mm to XLR cable and get an XLR microphone that is small in size?
5. UPDATE: After reading this discussion, I am wondering if my understanding about phantom power is correct for the Olympus ME-52W and ME-12 microphones? Do they indeed need the phantom power, or if this is something else. As quoted on that link:

"Just plug the TP-8 jack into the "MIC" jack of your recorder"

I am in a need of a microphone for a specific setup and with some requirements, but I don't seem to have much luck in finding the best option. There is a possibility I am looking at this all wrong, so I am asking for advice here.

My setup is as follows:

• The recording device is an Delock USB audio sound card

• The USB sound card is connected to an Raspberry PI electronic board

My requirements are:

• It does not have to be professional quality, I am hoping for something in the price range of 30€. Update: I understand that this budget is quite low, so it can go up reasonably if other requirements are met.

• Small microphone (i think the terms my be: bug, lavalier, lapel, although I am not certain about the differences, but you get the idea).

• Optimal sensitivity (I have used Genius MIC-01C with the sensitivity of -58dB at 1KHz and it was ok, but I think I would rather go above -45dB).

• The most important thing is the noise requirement. I have had bad experiences with the Genius microphone, because its cable would collect too much 50Hz noise from the environment. If it was near the fluorescent lamp or a power source of any kind, the noise it collected was too high for any usage. Even when it is not near the EM source, it still gets much 50Hz noise from the environment. This is the main reason I am looking for an alternative microphone. I guess this requirement could be summed up as a need for a shielded cable?

• The directionality should be unidirectional the narrower the better, because it is used to listen to one person only and try to eliminate anything else whenever possible.

What i have found in my search so far:

(I can't post more than two links yet, so here are only names)

• Sony ECM-CS3
• Bronstein LM15
• Olympus ME52W

My questions are:

1. Is there a microphone you know that would suit me these requirements?
2. The Olympus ME-52W is the best I have found, it has high sensitivity, noise reduction and it has direct 3.5mm connector so I can replace its cable with a shielded one very easily.

4. Do XLR cables help with this? Can i use a 3.5mm to XLR cable and get an XLR microphone that is small in size?

Finally:

Thank you for your patience and I am sorry if my questions are wrongly directed or nonsensical. I am grateful for any help or hints as to how to direct my search.

UPDATE: The ME52W has proven to be a bad choice due to phantom power, which i can't supply.
