Within a month of getting these headphones, the left ear is now constantly cutting out and barely plays at all.
Bought an entirely new cable thinking that would fix the issue but within a week i was having the same issue. Terrible quality control on these headphones. The left ear now doesn’t work at all making these unusable.
userlessIf you replaced the cable and it fixed it for a week and then cut out, that means it’s likely the MMCX connector on the earphone. (MMCX is not the greatest of connectors as they are fragile, much like a tiny BNC connector design minus the twist lock. But I don’t know why most DACs today have abandoned a BNC input in favor of RCA when BNC is a true 75 ohm connector, and also used in word clocks.)
I have an older DAC that I wouldn’t trade for the world! Its max input is 24/96 at 8x OS or 24/768 at NOS, but on a Sign-Magnitude DAC, anything higher would be pointless. People wish they could find DACs with these chips in them today but they can only occasionally find some with lower quality versions of the chip and less of them, as there were three grades to the chip. • The lowest of the grades with the poorest THD values was the PCM1704/PCM1704U; the middle version was the PCM1704U-J; the best one, the PCM1704U-K, which was about $40 when it came out in 2000 and $65 by 2010, and the last time I ever saw it being sold years after it was discontinued it was on eBay for $550. I have the best version on my DAC and I have 8 of them. As they are stereo chips, they are stacked as 8 mono channels per L & R sides to increase the THD and SNR performance. They require lots of power, matching digital filters, and also can have an FPGA working with the signal and change the variables for NOS, 1x, 2x, 4x, or 8x OS. It’s basically an R-2R in an IC package. Unfortunately most good DACs have op-amp outputs. Not this one. It’s a discrete powerhouse and weighs 41 lbs. It’s gotta be worth 5-10x its original price, but it’s an Audio-gd Reference 7.1 DSPv5.
euzaurusYou said “earpieces” in the review, hence I thought you were referring to the actual IE600 earpieces, not the earTIPS which is what the silicone things are actually called. Sorry if I offended you. I was trying to make light humor out of your musical taste.
Poor customer service, they claim that they sell without an option to return because they buy in bulk from the manufacturer to offer the lowest prices - NOT TRUE. I did not get the best price available at the time, it was cheaper on Amazon ($500 vs Drop $550), the cable did not work well and Drop did not reply to my return request. I guess I will not recommend nor buy at Drop ever again. I had to get third party tips because the ones from Sennheiser would always leave an air gap. The build quality of the IEM itself it is top notch but the cables are not good quality and proprietary you can't replace them.
I own the IE600, and it’s important to note that the connectors used are not standard MMCX connectors. While you can use standard MMCX cables, they may have a loose fit and potentially cause connection issues. The connectors on the original Sennheiser cable are approximately 1mm deeper, ensuring a secure and stable connection.
Kaxi85This is definitely true. If you look for inexpensive replacement cables on Alibaba, for example, you will see cables advertised as MMCX and you will see cables advertised as IE300/IE900. IE900 cables will not only have a smaller overall profile, the connectors are 0.89mm deeper.
ChatGPT’s explanation: “The MMCX connector is a widely used standard in in-ear monitors (IEMs), allowing for a secure yet swiveling connection between the earphones and the cable. The Sennheiser IE 900 connector employs a recessed MMCX connector to enhance durability and prevent strain. This recessed design ensures a more secure fit and reduces the risk of damage from frequent cable changes.“
This is the most I've ever spent on IEMs and they do sound great. My previous most expensive IEMs are the Sennheiser IE300 and these IE600 are certainly better, but honestly, not that that much better for the price difference. I guess the IE300 much punch above their price.
I don't know what words I can use to describe what I am hearing.
This is my very first IEMs and I was absolutely shocked by the sound quality.
Crystal clear, accurate you name it.
100% RECOMMEND IT!
I own the 300, 600, and TW and have to recommend all of them. They certainly have a similar signature, but they don’t sound the same. The 300s are my mowing IEMs, and the 600s are for at work. Technically punches much higher than the 300, with greater clarity and tighter bass. The 300s have a “thicker” sound, something that doesn’t bother me over the sound of the mower.
