Look, those fuzzy things are just windscreens to stop wind noise from ruining your audio. Since you are using the ZV-E10 II, I highly recommend sticking with a Sony mic because they use the digital hot shoe. I have tried many different setups over the years and cables are always the first thing to fail or get unplugged by accident when you are traveling. In my experience, the Sony ECM-G1 Vlogging Microphone is the safest bet for your budget. It is tiny, fits right on top, and you dont need any cables or batteries since it pulls power from the camera. If you want something a bit more professional for blocking out Tokyo city noise, look at the Sony ECM-B10 Compact Shotgun Microphone. It might be slightly over your budget but it is much more directional. Tbh, for a first timer, just get the G1. It is dead simple and very reliable.

I spent a month in Osaka filming street food and learned the hard way that wind kills audio. For a beginner, simplicity is key.

• Rode Wireless ME Compact Wireless Microphone System clips right to your shirt. It keeps your voice clear even in noisy crowds.
• Rode Lavalier GO Wearable Microphone is a wired option if you dont want to worry about charging more batteries. Both are solid for your budget.

Just catching up on this thread! Building on the earlier suggestion, I've spent a decade filming in chaotic cities and Tokyo is an absolute blast. The soundscape is incredible but super challenging tho. To help narrow this down:

• Are you mostly talking directly to the camera while walking, or filming interviews?
• Does that budget need to include extras like wind protection? Its amazing how much a smart investment saves you in editing later!
