Review: QAK Thump Blu Headphones


The OAK Thump Blu behind the neck headphones are light, wireless, comfortable, long playing, have good fidelity, and if the volume is kept to a reasonable level, you can hear environmental sounds with good acuity. The earphones are operated by six buttons, powered by an internal battery, and they wirelessly converse via Bluetooth to your phone or any Bluetooth-enabled device, allowing you to listen to music or have a hands-free headset. The Thump Blu comes with a USB cable, and is available in white, blue, green, pink, red and black colors and retails for $79.99.

Most of the headphones and earbuds on the market block out most of the exterior noise from the world, which is fine when you are in a safe environment and just want to immerse yourself in your music. In the world of sports, whether it’s running, hiking, walking, or biking, you need to pick up the ambient sounds and spatial cues in the world around you. For safety reasons, you want to be fully cognizant of your surroundings, so you can hear cars, traffic, dogs, wild animals, and other trail and road users. The design of the Thump Blu is sort of a cusp between open ear headphones and earbuds that just barely sit in your ear. The bend of the unit and the slight adhesion of the rubber tips of the ear pieces keep them in place, but it’s not enough to block out exterior sounds nor too hard for ear discomfort. Although you can crank the tunes up and really enjoy the music on a ride, if you want to be able to have a conversation and hear more subtle spacial environmental cues for safety reasons, then you need to keep the volume at a respectable level.

The Thump Blu is comprised of the neck band with its attached ear pieces, a USB port, three LED indicators on the rear bottom, and six rubberized control buttons on the outside of the ear pieces. Once the unit was paired with the phone for Bluetooth communication, subsequent paring wasn’t required, and you only had to turn the unit on and start the music from the phone to begin operation. The buttons by each ear piece are hard to locate sometimes, especially with gloved fingers, but the difficulty was lessened with some practice. Once you have the button locations memorized, you can play, pause, choose the next or previous song, adjust the volume, and answer calls. The Play/Pause and Answer buttons were the easiest to locate since they sit in the middle and have a raised bump, so you can use their positions to find the other buttons.

I liked that it used the typical mini B USB connector on the device itself for charging, since you always have those laying around the house. It quickly charged in around an hour’s time, and the battery life was 6-8 hours, which gave me at least a couple of rides before it started to die.

The ear piece’s adjustable rubber tips were comfortable and worked well, even when I got sweaty, or they got rained on, and although the bend kept them firmly in place, it was never enough to feel pinched or wedged into the ears. The inside edge of the band is rubberized for comfort, and helps alleviate any irritation from head movement. They fit nicely over or under the straps of all the helmets I wore, and depending on what type of eyewear you were using; the headband might be slightly altered in position, and the bend force decreased. I have found it was easier to leave it sitting around your neck when not listening to music, instead of jamming it into a pack, and it was never bothersome wearing it in that manner.

I thought they had pretty good fidelity and acoustics for a small Bluetooth device, and I enjoyed listening to a variety of music, from bombastic Black Sabbath to mellow Patty Griffith. They had decent bass, good midrange and had a slight roll off at the higher frequencies. The hands-free feature was useful, but I found it sounded hollow and lacking clarity in both directions, so I only used it for short periods of time. They had good wind noise reduction due to the light seal of the ear pieces, unless you were going Mach 1, or it was extremely windy out. The earphones stayed in place and retained the same fidelity on really rough terrain, and even though they might bounce around occasionally, it was never bothersome.

Bottom Line

I have really enjoyed my time with the Thump Blu behind the neck headphones. The lack of wires due to the Bluetooth connection is very beneficial for biking, especially when wearing a pack and dealing with rough terrain, or heavily wooded areas, since there is nothing to get snagged on. The Thump Blu has good fidelity, was light and comfortable, and stayed in place on any sort of terrain. Although the buttons were sometimes hard to locate, they provided the ability to play, pause, choose the next or previous song, adjust the volume, and answer calls. The hands-free feature was nice to have, but I found its quality somewhat lackluster. Its earphone design allows you to hear outside environmental cues, although you are most cognizant of things if the volume is kept to a respectable level. Of course, these suckers can crank if you want them to!

The QAK Thump Blu provides wireless Bluetooth connection to any capable device, has a quick charging battery with a long life, and it offers good fidelity and excellent comfort.

    The look like the motorala S9 headphone and I have a set. I do not like them for riding. If you wear glasses or sunglasses when you ride there is not enough room on your ear for both. Also audio quality is not great. Also using blue tooth drains the phone batter way faster then corded methods. I would just stick to a good set of earbuds.

  • Paul Lehman says:

    Was there any issue with the sweat/moisture interfering with the control buttons after prolonged use. I would agree these look like rebranded Motorola S10s. They were (are) notorious for losing controls after several months of use. I personally went through two pair of the Motorola S10s with this issue. Would be great to have a new model that works better.

  • David West says:

    This reminds me of the Motorola S11-Flex HD. Based on your review the Motorola might be a better buy. See the review and the images here, and you be the judge as to who copied who.

    I am on pair number 3 and that pair has just died. It’s been less than a year and they have repeatedly died on me. I like the way the work when they do work, but they are unreliable. The Qak does not get back to you very quickly and when they do they rave about the customer service, which is terrible. I only hope that on return 3 I can actually get my money back instead of pair 4 which will die in a couple months. I do not recommend these headphones at all!

    Terrible company, terrible product, stay away! These people are crooks!

    I’ve had problems with their new Xtreme model. Their customer service is snarky and issues remain unresolved.

    • Steve Watanabe says:

      Here’s more details on my issue with the Xtreme model.

      I purchased a Thump Xtreme at a Rock n Roll marathon expo. I previously used the LG LBS-730 but found that the ear plugs on the LG block out all external sound which isn’t good when running on the street. I thus bought the Thump Xtreme as it provided a looser fit. I had never heard of Thump so bought them on the basis of trying them at the expo. I’ve found that when running they tend to “cut out” at times even though my iPhone is only two feet away (the iPhone is in a flipbelt).

      I notified the manufacturer (previously and they said…”We are very sorry you are experiencing this.” and “We have included Todd in this email for advice in regards to your clipping issue that is occurring from two feet away from the headphones.”

      After a month I hadn’t heard anything further so I sent:

      It’s been a month and I haven’t received any further emails. The Thump Extreme still suffers from “clipping”. I’ve found that it is usable if the iPhone is on my back (I use a flip belt to do so). Anyways, I believe I either have a defective unit or this is a systemic design flaw.

      to which I received this response:

      “The Thump Xtreme is a bluetooth headphone.
      Bluetooth is a wave between items.
      If there is not a clear line of sight between the headset and pairing item clipping can occur.
      Clipping will occur more often when you are in the open.
      The bluetooth wave needs to bounce off objects to then pair with your headset.
      The design flaw is with bluetooth.
      It probably works better when it is on your back or arm wrap.”

      So far I’m living with the “clipping” as I can position the iPhone on my back and not move my head too far forward which seems to break the signal.

      Also, the blue/red light is very dim and hard to see in lighted areas. You can hold the on/off button for five seconds and the unit will turn on/off even if you can’t see the light change.

      The sound quality is good while allowing external sound to be heard (e.g. cars).

    Well now I feel like I need to edit my review. First let me start by saying that QAK offered me a set of free wired headphones the first time I had problems if I would right a nice review about how well their customer service is. And so I did because they were really pretty good the first go around. However they did suggest I wear my headphones upside down to keep sweat from shorting them out. REALLY!!!!! I did try it but they are just not designed to wear upside down. (or for sweat) So, after about 2 months with the new thump blu’s they sent me, I began to have problems again. I even started wearing a head band to cut down on the amount of sweat that makes it to the ear pieces. (I think this is where they are shorting out) I guess they just weren’t designed for people who sweat. Maybe they are better suited for use while driving your car or something like that. Anyway, I filed another warranty claim on or about October 7th stating that I can answer a call but the caller can not hear me. (I can still listen to my music while I run though) They responded with a question asking if the volume was turned up. I replied letting them know that the volume was in fact turned up. Keep in mind that my warranty expires November 22nd 2014. After 2 weeks of not hearing from them I replied to the original e-mail asking if they’ve made any decisions about my headphones and the warranty. Again I received no reply. Around November 3rd I submitted another warranty claim on their web site explaining everything once again and how I have not heard from them in almost a month. I have now even noticed that the skip and volume buttons do not work. Three days later still no reply. Arghhhh……I will say this, I do like the headphones. I have ran many 13+ mile runs with them and not really even notice I’m wearing them. I just really feel that they are waiting me out until my warranty expires. So, QAK, you have won! I give up. But I will let everyone I can know about the experience I’ve had with your customer service, the lack of service you have provided and your failure to make good on your warranty. But on the bright side (because I try to be a positive person) I have a nice $80 case that I can keep future headphones in (when I find a new brand)and when people ask me about the “Thump” logo on it I can tell them it is a very good case and enlighten them on why they should not buy any QAK headphones!
