Yamaha EP-E50A Bluetooth Earphone Disconnection Repair

Hello, it's the incompetent one here.

I got a Yamaha EP-E50A at E-earphone for ¥200 as junk, with the issue 'no sound from one side'.

I thought I'd cut and resolder from one end if I couldn't find the broken wire, but the left side wasn't producing sound, and when I moved the base of the battery part nearby, sound would occasionally come through.

It seems the wire is about to break from the gold-shining press-fit component for fixation in the photo above.

It was quite thin and difficult, but I removed the metal fitting and used the wire located before it.

The soldering is messy, but please forgive me (´・ω・｀).

I even want to praise myself for soldering with the parts so close together and unable to be fixed in place; I really did my best (´；ω；｀).

The rest was glued and fixed with synthetic rubber adhesive, and that's it.

I naturally replaced the ear tips and wiped down the housing with ethanol, and I was done.

Regarding the Sound

The comparison target is BOSE SoundSport.
It's a bit harsh to compare products from different price ranges, so I'll keep it moderate.

My first impression was that the treble was piercing... but it was a matter of getting used to it.
Since BOSE SoundSport emphasizes bass to mid-range strongly, perhaps my ears were just surprised.

Besides punk and folk, I like Free Jazz, so it's an excellent match for listening to organists and saxophonists.
Especially for Don Cherry's "Om Shanti Om," which is a personal favorite album of mine, Don Cherry's vocals come forward, and the treble's clarity is pleasing.

If you can buy it in this price range, wouldn't it fall into a good category?

It might be recommendable for those who want to listen to older music with decent sound.
For recent music, there's a tendency to demand more bass, so there's a possibility that the bass might feel insufficient.

I felt it had excellent compatibility with music genres mainly up to around 1975, before punk and hardcore became prominent.
While some other reviews were negative, it doesn't seem like such a bad product to me.

Moreover, since it's not a truly wireless type, there's no worry about losing it.
I've lost fully wireless earphones about 3 to 5 times in a month in the past, so I don't want to buy them anymore.

Well then.

Until next time.
