I bought this at the airport in CO, and was bummed to find out it wouldn't stay in our samsung tablet port at all, so the sound kept cutting in and out and was basically useless.  I was long gone from CO before I realized it, so couldn't return it since I threw away the packaging.  bummer.  do not buy this.

I purchased this in April for a show, which ultimately got cancelled.  For the first time, I am now trying to use it for a show and it is DEFECTIVE.  Audio cuts out constantly.  I tried using diff cables to test out issue and that did not resolve.  so it is either the headphones or the unit itself.  Amazon will not let me replace/switch out item.  WTF?  I hope you guys can help me resolve this.

I bought this headset based on the Multi-IEM review on Head-Fi and user reviews on Amazon. I must say that I really enjoyed the sound character and tonal quality of this headset.

Unfortunately, sound stopped working in the left ear 45 days after I bought it with light use. I do travel often but doesn't use this headset on a daily basis. The mic, which is on the left side, still works. If I tug the wire, sound would come out, but for all intent and purposes, the headset is useless now. I've always been careful, rolling the cord and putting it in a pouch for storage.

I've had many cheaper and not as nice sounding headsets that've lasted much longer than this. I must say I'm severely disappointed with this product and would be reluctant to recommend it to any frequent travelers.

I'm not sure if the manufacture's warranty would cover this type of issue. But due to my frequent traveling schedule, it's not really convenient for me to send it in for repairs. I hope Beyerdynamic reads these reviews and take steps to improve the build quality of their products.

I was amazed when I took this unit out of the box and saw that it was made in Japan, not in China.  I was expecting a smooth ride with a quality piece of hardware.  I installed the drivers, then plugged in the unit.  Everything came right up, except for sound.  I checked all my connections, played with volume, and then noticed that my laptop's sound was completely non-functional, not just the sound from the Plextor. Rebooting didn't solve the problem.  I had to roll back to a restore point to get my sound back.  I tried once again, this time using the drivers downloaded from Plextor's web site, which were newer than those on the included CD.  Everything came up perfectly, including sound.  I played for about 15 minutes, and then my notebook's sound was gone again.

I emailed tech support; their response (after four days) was to reinstall the drivers.  Gee, thanks.  I was very disappointed to have to pack it up and return it to Amazon.

Bought this late September, tested it out a seemed to work fine. But it conked out the first time I took it out to use it full force for an event. I can't return it anymore because it's been a couple months but it worked when I tested it, just not when I actually took in the streets. The audio continues to cut in and out so I can't use this at all.

It pains me to give a bad review because I truly had high hopes for this boombox.  I finally decided to become a subscriber and purchased the SKYFi2 receiver so I could take it from my truck to my office.  I purchased the boombox for the office part of the equation.

I disregarded the reviews that complained about a constant high-pitch sound, hoping that it was related to the SkyFi and that the SkyFi2 (second generation) would have corrected the problem - no luck.

The moment I popped the receiver into the unit I knew I was in trouble - the high-pitched noise was there and because I listen to music at a fairly low volume I could always hear it.  Even at higher volumes it was still distracting.  Moving/extending the antenna made no difference at all.

15 minutes after it came out of the box, it was back in and waiting on a table to be returned.  Very disappointing.  I don't understand why Delphi would distribute such a bad product.  I need to find some kind of solution to be able to listen to XM in my office, but unfortunately this boombox is not going to be it.

I tried it once and everything worked great for about 5 minutes so I turned it off. I went back later that evening and the L+R sound refused to work. I would definitely pass on this purchase.

I couldn't have been more excited about the convenience of these bluetooth headphones, along with the sound quality. That was, until, I realized they barely ever worked correctly. Yes, the sound was amazing...but this did not last. I live in New York City and anytime I am in Manhattan, the sound constantly cuts in and out (mostly out) to the point where I can't even bare to listen to them anymore. Unfortunately the window for returning this item has passed and I am stuck with non-functioning headphones.

Gave it up after a while, the mute button doesn't work and will actually play your speakers sound to whomever your talking with on the mic. The mic also has a habit of cutting out.

I bought this and took it home and had no trouble programming it and I even like the menus and album scrolling. But then I plugged it in and listened. And listened. If you are in a sound proof room, preferably a vacuum, you might be able to enjoy music on this player. But if there is a car nearby, or a crying baby, or an airplane, or a teenybopper, you will not be able to hear anything. It is the quietest player I have ever had. And then I plugged it into the jack of my Toyota truck, turned the volume up on both the player and the truck sound, and could barely hear the music. I have been on the website trying to figure out why they would put out a player you can only listen to in a vacuum, and I figure it must have something to do with ear damage lawsuits or something. So I went back to my old Boomgear player with LOTS of volume, at least enough to drive the speakers in my truck sound system. I was really disappointed because the RCA had all the features I wanted, like AAA battery instead of recharging so I could keep it in my truck. Too bad.

I bought this for my recently deceased Acer Aspire (on which I ran Fedora 20 Linux), which had a broken headphone jack. I thought this would be a solution, but it was not. It would only make noise through the headphones if the computer's volume was turned almost all the way up, and even then it was very bad quality. I don't think this is a software issue because it did "work," I guess. It just was really crappy.

Cable did not stay connected and would lose signal. Sound would cut out.

I bought this speaker based off of a recommendation on Wire Cutter, and I won't be trusting their reviews again. If only Wren had put as much work into the sound and the bluetooth functionality as they did the design. I probably could have lived with the sub-par sound if the bluetooth would've functioned.

First off, I connected 3 different bluetooth devices (a Macbook Pro and two different Android phones) to the speaker, and every connection was a surprise. I followed the instructions to connect a device, repeated it several times, turned the device off and back on, unplugged it and plugged it back it, and I couldn't figure out a rhyme or reason to how connecting to this speaker actually works.

After I finally got my devices connected, the sound quality over bluetooth was horrible:
- On my Macbook, it was staticy at times and also interfered with my Apple Magic Mouse bluetooth connection. The static always coincided with my magic mouse disconnecting and reconnecting.
- With my Android phones, it was another mixed bag. On one I couldn't get anything to actually play on it. On the other it would cut sound every dozen seconds or so, but the phone showed the music was still playing, then suddenly the sound would come back is if it just silenced the sound for those few seconds.

I honestly have not had such a hard time pairing a bluetooth speaker to a phone or computer before, nor have I had so many bluetooth connectivity issues. A speaker is only worth how it sounds and connects to an audio source. This "speaker" is pretty much just an expensive, pretty paperweight. Skip this speaker and go with a more well-known brand.

The initial first month and half were great, sound quality was beyond what I expected and the user interface in the program included allowed a ton of features... but the first problems started with the headset dying, 10 hours of battery life was a lie to me, I had to constantly have it plugged into the WALL OUTLET (not my computer) for it to even work, then all of a sudden, the Bluetooth receiver that I needed to use for it to work constantly disconnected the headphones every 5 minutes, so I returned it for a replacement. Waited a couple weeks and the new headphones came in, hooked everything up and everything seemed to be working fine, so lets test how my music sounds. The left speaker is completely dead. I'm pretty savvy with computers and sound design is something I've been doing for about 5 years so I tried everything I could to possibly fix this problem, nothing worked. I'm tired of this frustration of dealing with their headphones and will tell everyone I know to not buy any audio products from them to save them the hassle of dealing with this.

The sound quality is no better or worse than the $25 portable speaker I was replacing. The hardware and functionality are what made this a poor choice. As almost every other review has mentioned the connectivity is terrible and the speaker drops out/shuts down at random times. For me the worst part is the pops and crackling you hear if there is no active sound playing. In between songs or if you've paused your player, you'll hear constant noise coming from the speaker like an old LP record left to spin on it's last groove.

Bought this after I already purchased the VIZIO M55-C2 55-Inch TV and was not happy with the sound from the TV, especially during live sports. When I first mounted this Sound Bar I used the included optical cable, and for several weeks noticed the sound dropping from the rear speakers- it kept cutting in/out. I was about to contact Vizio about this thinking I had a bad speaker or bad speaker cable but I ended up replacing the optical cable with a heavier duty one- issue resolved, sound no longer cuts out

I used them for less than a month and out of nothing one of the earplugs stopped working. I only used it to listen to music on my android device or laptop, I never used them to go running or walking. I tried  using the product once to go running but the sound was horrible, for some reason it sounded as if  the sound was being cut.  It is a bit disappointing because when it worked it actually had a really awesome sound.
