To start, they sound great. Just great! Very balanced and a real pleasure to listen to music through them.
Unfortunately, that's about where the good things end. About 2 weeks into using these, very lightly (I commute to work on a train, and walk as well, and take very good care of my things.), a small tear appeared in the braided cord sheathing on the bottom half of the headphones. No problem, I thought, really isn't that bad. I continued to always return the headphones to their little zippered pouch, and chalked it up to some wear and tear. Over the next few days, the tear got bigger and bigger, until the wire inside was popping out. It was impossible to get back in.
I suffered through it for another couple weeks before the sound in my left earbud went totally dead. If I jiggled the earbud, it would sometimes comes back, but at this point I was a bit sour about my $79 headphone purchase and decided to contact HiFiMan. Big mistake.
They told me to ship them the headphones back and they would send me a replacement paid. That sounds like a fine exchange, except they only respond to emails at 11PM and in very broken English. I agreed and shipped them the broken headphones at a cost of $10. A week later I received my replacement pair; a pair of headhones in a small plastic ziplock bag with no accessories or manual or anything. Fine, I thought, I guess that's how they do it here.
I plugged in my new headphones, excited to finally have them back after a week of reading Reddit on my phone on my commute. Except this time, the right ear was immediately broken. No sound at all. Not even jiggling it worked. Frustrating. Now I'll have to deal with Customer Service again. Ugh.
I said this time I wouldn't pay to ship them back, that they'd have to provide a label. I also said I wanted a BRAND NEW pair, since it was apparent they sent me some refurbished pair that wasn't actually refurbished, since you know, they didn't work. After 4 days of emails back and forth, they sent me the label and I shipped off the headphones. The customer service guy, Hong, agreed to send a BRAND NEW pair. Another week goes by, another week of browsing Reddit. There are only so many interesting AskReddit threads to read before you get bored, trust me.
A week goes by and I'm excited to get my new pair and finally end this nightmare. I track my package every day, and today is the day they arrive! I rush home from work and open my package. Sitting in front of me is another small ziplock bag with another refurbished pair of headphones. I shudder inside, for I know this nightmare will never end. I plug them in, hesitantly, and they actually work. Fine, I thought, I'll just hope these are functioning and continue on with my life.
It's been 1 week since I've received that pair, and there is already a big tear in my braided cord. I have no strength left to deal with their sub-par customer service. long waiting times and empty promises. I will have to simply move on, bite the bullet on these headphones and look elsewhere for a serviceable pair. It's a shame, as these really do sound great.
Don't make the same mistake I did. The headache involved here is not worth $79. It's not even worth $59. Look elsewhere.
1. I found that HifiMan actually updated the cable design (see picture) to correct the previous point of failure
2. HifiMan reached out to me, thanked me for being a loyal customer and assured me that they will stand behind their product with the warranty. Their customer service has been good to me in the past, and while I don't anticipate needing to use the warranty with the improved design, it was reassuring to know that I am covered if things go wrong
I have been a longtime customer and user of HifiMan IEMs, starting with the RE-0. I am a big fan of their sound, so it is no surprise that this pair also sound phenomenal out of the box. The RE-400 have the most neutral sound of all the HifiMan's IEMs that I've owned, and sound quality is comparable to IEMs that cost 3-4x times more. They are also the most comfortable for extended listening.
However, as the company grew I also expected them to improve their build quality. I am sad to report that every HifiMan product I've owned died due to build quality issues. Baby them and they may last a year or two. Take them out to the gym and you'll be looking for a new pair in weeks. When they work, they sound fantastic. But they don't work for long.
Dr. Fang Bian and team need to step up the quality to truly grow as a brand. Use better components, hire more QA folks, and charge a little more. I would gladly pay more for a pair that are built like Sennheiser but sound like HifiMan :)
The tips do a great job of isolating and definitely give you many options for getting just the right fit, but without an internal vent, they seal in a bit TOO well, which isn't comfortable.
Construction seems solid, but as I was walking with them, I got a bit of cord noise as they rubbed against my clothes, which detracted from the experience, but sitting quietly in one place posed no issues.
