Question about Bose in-ear headphones - Black with black/white cord

2 Answers

My left earbud no longer produces sound! I was jogging with the earbuds and it started getting static and cutting out. I took them out thinking maybe some sweat got in them or something. I let them sit overnight and today, the right one still works perfectly, the left one is DEAD. Any suggestions?

    I noticed last night, I've owned these headphones for two years now, that the sound output between the 'in-ear' and the 'out-of-ear' speaker were switched on my left headphone.

Whatever the problem is give a call to Bose customer support(800-999-2673) and u can talk with them to get a replacement. If u r in one year warranty they will replace it(even if havnt bought it at bose store)...otherwise they will charge $50 i believe

Left earbud has no sound


I had this problem with 2 of my HBS 700s. The speaker in the earbud goes bad and needs to be replaced. If it is still under waranty you can send it in to be replaced (trying a home repair will probably void your waranty so try this at your own risk). If it is out of waranty and you have experience with a soldering iron, the earbuds can be replaced with a plain set that look similar to the originals from your local store (Wallgreens has a good selection for like $10). I am a novice at these things but the solution was pretty easy and has worked for both of my earbuds. I actually improved the quality of sound by installing better earbuds.

3d9a9467-2679-44c4-ba93-679ba93f6b9d.jpgYou will need:
- 1 small soldering iron
- one set of new wired earbuds (no volume control or mic... just plain earbuds)
- jewlers phillips head screwdriver
- one small flat screwdriver or thin flat edge to pry the cover off.
- one needle or thumbtack
Directions are the same for both sides. I suggest doing one side at a time and repeating the steps for the other side.
Directions:
- TURN OFF HBS 700
- locate the rubber plug on the bottom of the case (one on each side above the L and R symbols) and remove the plug with a needle.
- remove the screw located under the plug
d49d0cf9-a723-46a8-9565-47c904450fdf.jpg
- use a jewelers flathead screwdriver or thin flat edge to pry the case appart. The best method is to gently pry the bottom of the case outward then push in and up on the top part of the case starting at the back of the plastic case (where the earbud wire comes out) and working your way forward.

- remove the earbud cup and set aside. (if working on left side, also remove the charger door.)
- the circut board is held in place by plastic arms on the sides. Gently pry the circut board away from the case and lift up where the arms are holding it in place.
4865fbac-05ba-4dcd-bd70-b4bb366d79c7.jpg
- once case is removed from circut board, you will see where the earbud soldered to the board.

NOW FOR THE FUN STUFF...
-cut your replacement earbuds to length and expose about 1/4" of the two wires inside (usually one gold and one colored or one solid color and one multi colored).
-The two wires are coated to prevent them from shorting out while touching. Add solder to your soldering iron so there is a good drop hanging from the tip. Insert one wire at a time into the drop of solder (about 1/32" will do) and hold it there for a few seconds. This will melt the coating and allow the solder to stick to the wire.
BE CAREFUL NOT TO SOLDER TOO MUCH OF THE WIRE OR IT WILL TOUCH THE OTHER AND SHORT OUT! ONLY A LITTLE ON THE TIP OF THE WIRE WILL DO.
-carefully use the soldering iron to remove the old earbuds from the circut board. A small soldering iron with a sharp tip works much better than the standard size at this. The soldering points for +/- are VERY close together so becareful not to melt them together.
-solder the new earbuds in place of the old ones. + to + and - to -.
-tie a knot in the earbud wire close to the circut board so it does not pull free from the case when closed.

-at this point in my repair, I turned the HBS 700 on to listen for the startup tone to make sure the earbud was connected properly. I DO NOT RECOMMEND TURNING IT ON OR TOUCHING COMPONENTS WHILE IT IS ON. IF YOU WISH TO CHECK IT AT THIS POINT LIKE I DID, DO SO AT YOUR OWN RISK. ALSO, MAKE SURE NOT TO HOLD THE CIRCUT BOARD OR TOUCH IT WHILE IT IS ON AND TURN IT OFF BEFORE CONTINUING.

NOW IT'S TIME TO PUT IT ALL BACK TOGETHER.
-reinsert the circut board to the top cover in reverse of how you took it out. Do not force it and make sure all the plastic arms clip over the circut board securely. Make sure to press the buttons to see if the are seated right.
-replace the earbud cup, battery door and power switch if it fell off.
-attach the bottom cover making sure to leave the knot on the inside of the cover. The cover should snap on easily.
-Re-insert the screw and plug.
DONE!

If you wish your new earbuds to attach magnettically to the cup, you will need to break open the old earbuds and remove the magnets from inside. Then glue them to the outside of the new earbuds or drill a hole for them to sit in and glue them in. Be careful tho because drilling holes too deep in the new earbuds could damage the wires inside (I found that out the hard way)

Why did my left earbud become silent?


Hi,
you can make both of the earbuds work. You can open the earbud where the speaker is that you use to hear the musik. Use a soldering iron and a lead. check if the wire inside has removed, fix it back and you will hear sound on both earbuds.

Take care.

I have lost sound in the left earpiece. Are they history?


i think i might have fixed the same problem i had with mine. I took off the gel cover thing and put a tack or saefty pin in the hole of the gray speaker cover. pull the cover out and clean all the ear wax off the speaker part. it works great now after i cleared the ear wax from the sound hole.

Left earbud problems


Well, I had the same problem with the right earbud. Luckily I was under warranty with Target, so they told me to contact Bose. I did and they had me send in the headphones (to make sure I waas telling the truth) and about 2 weeks later I got my earbuds back. Their customer service is excellent, so that's what I would reccomend

Sony MDR-NC11 Left Earbud has no sound


They should come apart right where the metal meets the plastic, just below the buds themselves - be careful, one set like that I took apart were actually surface-mounted to the housing, there weren't any leads to repair...

Sweat got into earbud- sound very faint


That happens because the water and saline solution in the sweat are causing the wires inside the earbud shorting to each other, or shorting to the earbud casing that is grounded.

Let the earbud dry out in few hours or more, if the problem does not go away, then get replacement heaphones, it means that oxide formation on the contacts is causing a short.

Do not use shorted hearphones they can cause damage to the connected device.

Regards.

Sound in left earbud shorts in and out


If its not hard to open the case, just solder the connection again (only if you found out that the problem is inside).
Also check the wire if it have 100% connection. You may also check skin of the wire. If found out no good, so possibly this could fix the problem.

My left earbuds on my JVC gummy earphones went out.


I have this problem all the time with my JVC earbuds. This may sound a little gross but it will work. I put the ear phone in my mouth and **** on the end of it pretty hard. What I have found is that sweat or even wax will plug the little hole and prevent the sound from coming out.
