ikko Zerda ITM01 Portable Headphone Amplifier, 3.5mm Audio DAC Detachable Magnetic Cable Adapter, Use ESS9298 High Performance Custom DAC Chip,Full System Compatibility（3.5mm Lightning）

Sound is good and it has enough power to drive big headphones, unfortunately the proprietary cable and the fact that you have to stay still while using this device or it’ll cut out the sound if the cable moves ,makes it a no go,,

I purchased two new sealed units from Ikko thru Amazon. The first unit powered on but didn’t play any music thru my headphones. The second unit wouldn’t power on at all. I unplugged the Zerda and fiddled with the magnetic cable and plugged it back into my iPhone and my iPhone immediately restarted. Loud pops were now coming thru my headphones so I immediately unplugged them. iPhone recognized the Zerda but no lights on the Zerda and no sound. Unplugged, replugged, and the iPhone immediately went dead. After a hard reset I decided not to try this product anymore and return it. I was lucky that no lasting damage happened to my phone and headphones.

Sound quality is very good, but cable disconnects easily, so not suitable for your pocket, had an issue with the cable, contacted customer service from ikko and they provided a replacement very quickly, so overall very good..

Pros-light weightGood choice of cables for mobile and computer.3 different sound profiles that actually workCheap, only $60Cons- didn’t work at first in my iPhone using the lightning cable. Randomly works on my iPhone. Sometimes it does, sometimes it doesn’t.Constant crackle and pops.Worked on my Mac just fine but still get pops and crackles.Proprietary cables, bad move. I don’t see what benefit you get with prorietary cables, especially when they are not readily available.Summary. No. Big no. Sound doesn’t justify the cons, way better options that work flawlessly. Spend more money and get a dragonfly black for $99 (better build, works all the time, sounds great) or get monoprice’s usb dac (same build quality, usb a, works all the time, same price and sounds great).Again. No. A big no. There are tons of better options for the same price or a little more. Stay away from this.

Sometimes works, sometimes don't, sound it's ok, tested in iPhone xs and iPhone 12, propietary cables it's a big no no, only lasted for 2 months, now it's completely dead, doesn't turn on, spend more and buy a better product. I don't recommend this product.

Stop producing any audio, in one channel, after two days of use. With headphones would only provide audio to one ear. Take a hard pass on this one.

Out of the box it sounds pretty good.

Excelente producto fue un regalo y quedaron maravillado.

Unit doesn't work out of the box. And now i have to pay shipping to return it to get my refund.

Pro: Sound quality is good, it has enough power to drive large 32 ohm headphones (I guess even 80 ohms would be ok)Con: The cable is not suitable for mobile use. It disconnects randomly when handled. Movement either on the magnetic side or the Lightning connector will disturb the connection, which will result in pops and crackles.I returned this item.

Pues este es un muy accesible DAC/AMP. tiene buenas prestaciones para el precio y es muy cómodo cuando usas dispositivos iOS. Aunque la caja diga “sin interferencias” si suele tener interferencias, se escucha “ruido” en la música si se mueve. No sé si sea por el iman en la conexión o el tipo de cable.

Sur papier le promesses sont là mais à la réception cela ne marche pas, le produit n'est pas solide. A fuir
